nootropicguy directs readers to a full thread on the ingredients in a testosterone-boosting product. He says it explains why the claimed boost is not surprising, and offers a discount code.
The author claims most fiber supplements are a scam and that Sunfiber (PHGG) works, citing 120+ human trials and benefits for butyrate, gut barrier, constipation, bloating, IBS and SIBO. They say they personally use it daily.
nootropicguy claims Sunfiber's gut benefits extend to brain benefits. He cites a recent human trial (26% more refreshed on waking, 34% less fatigue, 24% more motivation, better memory) and preclinical findings (raised brain dopamine, lower neuroinflammation, reversal of depression models, improved TBI recovery).
Author claims DSIP is an underrated peptide for addiction recovery, citing 97% success in opioid withdrawal and 87% in alcohol withdrawal, with minimal tolerance and side effects. Author says two other small open-label human trials showed similar results.
nootropicguy claims DSIP restores systems damaged by addiction. He says it triggers Met-enkephalin release, potentiates GABA, blocks NMDA receptors, and normalizes sleep homeostasis, the HPA axis, circadian rhythm, and autonomic function.
Author argues BDNF is not the answer for addiction because raising it in the wrong brain regions may worsen cravings and relapse risk, and that GDNF is the real anti-addiction target. The post is shared with a quoted user's question about sourcing a nasal product.
nootropicguy claims GDNF underlies ibogaine's strong anti-addictive effect. He says ibogaine should be a last resort, used only with proper medical oversight because of potentially fatal cardiotoxicity.
nootropicguy lists things he would consider for boosting GDNF to repair the dopaminergic system and counter addiction: sodium butyrate, co-micronized PEA plus luteolin, low dose naltrexone, rehmannia, sunlight, ALCAR, and DHA. He adds that bromantane may also help.
nootropicguy corrects his previous post, saying bromantane is a drug and not a supplement.
The author lists ten supplements and lifestyle measures as an alternative to Adderall for ADHD, with claimed comparisons to Ritalin, and asserts it is almost impossible not to notice benefit.
nootropicguy lists 'honorable mentions' for ADHD beyond Adderall: zinc (30mg claimed to cut stimulant dose by 37%), a 36-in-1 micronutrient (benefit in 3 human trials), magnesium (claims up to 95% of ADHD kids are deficient), vitamin D (modest add-on benefit in 4 trials) and phosphatidylserine (small benefit at 200mg/day).
nootropicguy says Notable Focus contains Sabroxy, Thai Ginger (enXtra) and Ginkgo, and that Notable also sells the 'strongest saffron on the market'. He recommends science bio or swisschems for bromantane (for research purposes), and Swanson for catuaba and Muira Puama, saying he was 'insanely impressed' by catuaba. A link is included.
Author argues Ray Peat is wrong to compare resveratrol to DES. The author claims resveratrol binds estrogen receptors far more weakly than DES or estradiol, suppresses inflammatory genes rather than activating proliferative ones, and showed no carcinogenic signal in human megadose studies. The post quotes KruseYouri's "Ray Peat on resveratrol" post.
nootropicguy adds that resveratrol is not a proliferative agonist like estradiol or DES. He claims it is pathway-selective for anti-inflammatory signaling rather than cell growth, so its very weak estrogen-receptor binding is not relevant. This continues his own post disputing Ray Peat on resveratrol.
The author announces a Loxstar Cyber Monday sale of 35% off for the next 10 hours, with the next restock in 2026, and links to it. It quotes VanceE's post 'Supplements don't work'.
The author announces a hair growth serum he says took eight months to formulate. It contains RCP peptides, melatonin, rosemary and caffeine, which he claims match minoxidil in effect, plus ten other ingredients. The discount code CYBER35 is offered.
The author announces AURABIŌM, a product developed with a tagged account, described with claims of diamond peptides with 90x bioavailability, micro copper peptides with 3x penetration, and 10+ peptides plus stem cells. It introduces a thread, and the retrieved text gives no explanatory health content.
nootropicguy opens the product thread by giving a link to the product before explaining its formula.
nootropicguy claims 99% of peptide serums fail because they dissociate, degrade, oxidize or can't penetrate, calling them marketing, and contrasts this with his product made by scientists.
nootropicguy claims most copper peptide serums cause oxidative damage and that his microencapsulated GHK-Cu has 3x penetration, keeps copper bound, causes no oxidative stress, and gave 55.8% wrinkle reduction, described as peer-reviewed.
nootropicguy says his product's pentapeptide is conjugated to diamonds, claiming 90x bioavailability, 70% ATP production and 67% collagen synthesis, while asserting competitors' peptides degrade in the bottle.
nootropicguy claims standard hyaluronic acid molecules are too large to penetrate skin and only hydrate dead cells, calling it a scam and "theater."
nootropicguy says his 4D hyaluronic acid uses four molecular weights to reach four skin layers, claiming 155% immediate hydration boost, 110% increase versus regular at 1 hour, 26% less wrinkle depth at 60 days and 22% elasticity boost at 4 weeks.
nootropicguy claims Pycnogenol is 20x more potent than vitamin C and recycles oxidized vitamin C, with UVA/UVB protection, blocking collagen breakdown and anti-acne effects (75% improved in a study); he says a $50 vitamin C serum is likely already oxidized.
nootropicguy claims 80% of visible aging comes from oxidative damage, that most antioxidant serums can't prove neutralization, and that his spin-trap antioxidant shows 82% hydroxyl radical scavenging (EPR-validated) and regenerates.
nootropicguy recaps his product's ingredients: micro GHK-Cu, diamond pentapeptide, 4D hyaluronic acid, Pycnogenol and spin trap, plus more actives on the site, framing it as beating "Big Skincare."
nootropicguy says AURABIŌM took 18 months to formulate, that every ingredient was chosen 'for delivery, not marketing', and that the product is available now. The post itself names no ingredients; the parent post lists peptides and antioxidants.
The Biohacking Immortal · @1immortals1

Specific clinical benefits include cortisol reduction, improved VO2 max, testosterone increase, anxiety reduction, sleep quality improvement, and cognitive enhancement. Recommends 600mg KSM-66 extract daily taken in evening, paired with magnesium threonate.
Omega-3 supplementation efficacy depends on chemical form and dose. Ethyl ester form (common, cheap) has ~20–30% bioavailability vs. triglyceride form (~70%+). Clinical benefits require 2,000–4,000 mg EPA+DHA daily; most capsules contain only 300 mg, yielding subtherapeutic dosing. Proper storage (refrigeration) prevents oxidation. Recommends triglyceride form at 3,000 mg EPA+DHA daily.
Vitamin D deficiency (42% of American adults, >70% in northern latitudes in winter) is a hormone precursor regulating >1000 genes. Deficiency correlates with depression, 2x all-cause mortality risk, reduced testosterone, impaired immune function, poor calcium absorption, and reduced insulin sensitivity. Standard dosing inadequate; 5,000-10,000 IU daily for 8-12 weeks recommended for deficiency, then 4,000-5,000 IU maintenance. Take with fat and pair with K2.
1immortals1 posts only 'More at:' with a link. No substantive claim is in this post.

Provides clinically effective doses for active compounds and cost comparison for individual purchasing.
1immortals1 posts a generic call to follow the account for more biohacking knowledge.
Turmeric's active compound curcumin has near-zero bioavailability when taken alone; piperine (black pepper) increases absorption up to 2000%; liposomal or phytosome formulations improve delivery; standard supplements often ineffective.
Caffeine blocks adenosine receptors rather than providing energy; optimal timing is 90-120 minutes after waking to avoid interfering with cortisol rhythm and building tolerance; 5-6 hour half-life means afternoon caffeine reduces deep sleep quality.
Collagen supplements are broken down into amino acids like all proteins; hydrolyzed collagen peptides may signal increased collagen production rather than providing building material; effective doses are 10-15g daily for 8-12 weeks; typical 2g doses are subtherapeutic.
Author explains zinc's role in testosterone production and male health, discusses prevalence of deficiency due to modern diet and lifestyle factors, distinguishes bioavailable zinc forms, recommends dosing and duration, and warns against copper depletion from excessive intake.

Brown adipose tissue activation converts stored fat to heat. Compared favorably to expensive cryotherapy; no crash or tolerance development.
Seed oils (canola, soybean, sunflower, safflower, corn, cottonseed) dominate modern food supply despite health concerns. High linoleic acid (omega-6) content creates inflammatory cascade through arachidonic acid conversion. Western diet omega-6:omega-3 ratio 15-25:1 versus historical 1-4:1. Linoleic acid incorporated into cell membranes increases oxidative damage susceptibility. Seed oils extracted with hexane and processed at high temperature producing trans fats and oxidized byproducts. Recommendation to replace with butter, ghee, coconut oil, tallow or extra virgin olive oil.
Author promotes tongkat ali supplement as testosterone booster with specific clinical evidence. Claims it increases free testosterone 37% in 4 weeks via SHBG reduction without suppressing natural production.

Boron supplementation increases free testosterone by 28% within 7 days and decreases free estradiol by 39% through SHBG reduction. Mechanism: boron reduces sex hormone binding globulin, freeing already-produced testosterone. Additional benefits: reduces inflammatory biomarkers, improves vitamin D metabolism, enhances magnesium absorption, supports bone density. Average diet provides 1-3 mg; studies used 6-10 mg daily at cost of $0.03-0.04/day.
75% of population chronically dehydrated; plain water without electrolytes worsens hydration by diluting depleted minerals. Cells hydrate based on sodium-potassium gradient across cell membrane, not water volume alone. Sodium drives water into cells, potassium is intracellular electrolyte critical for heart/muscle/nerve function. Magnesium lost through sweat. Low electrolytes cause muscle cramps, palpitations, brain fog, afternoon energy crashes, and reduced cognitive performance.

A 20-year Finnish study of 2,315 men showed sauna use 4-7 times per week reduced cardiovascular mortality by 50% and all-cause mortality by 40% compared to once-weekly use, with dose-dependent relationship comparable to regular exercise. Mechanism involves heat shock protein activation triggering cellular repair and protection cascades.
Glycine is the only amino acid shown to improve sleep quality as effectively as pharmaceutical sleep aids without cognitive impairment, dependency, or morning grogginess. Mechanism involves NMDA receptor modulation and core body temperature reduction. 3g nightly costs $0.05 vs $3-8 per Ambien pill, improves sleep architecture without suppressing REM sleep.
Quercetin, a flavonoid from apples and onions, selectively destroys senescent cells ('zombie cells') that accumulate with age and drive aging through inflammatory SASP secretion. Multiple mechanisms described including senolytic activity, anti-inflammatory effects, antioxidant activity, and zinc ionophore activity; dosing recommendations for supplementation.
DHA (docosahexaenoic acid) is the primary structural fat in neuronal membranes; omega-3 supplementation supports cognitive function through membrane fluidity, reduces neuroinflammation, and lowers triglycerides. Plant-based ALA conversion insufficient; supplemental DHA or fatty fish necessary for optimal brain composition in most Western populations.
Author argues nasal breathing produces nitric oxide in sinuses, increasing blood oxygen absorption by 10–15% versus mouth breathing. Claims measurable oxygen saturation differences, antiviral/antibacterial effects, parasympathetic activation, and effects on facial structure. Recommends nasal-only breathing practice and mouth taping during sleep.

Contrasts research evidence with commercial cold plunge marketing and provides accessible implementation guidance.
Most omega-3 supplements fail to deliver benefits due to use of ethyl ester form (20% bioavailability) instead of triglyceride form (70%+ bioavailability) and insufficient dosing; clinical efficacy requires 2,000-4,000 mg EPA+DHA daily; proper storage critical to prevent oxidation.
Taurine supplementation extended lifespan 10-12% in mice and improved healthspan markers; taurine blood levels decline 80%+ with age, correlating with aging markers; restoring to youthful levels reversed multiple age-related declines. Research dose 3-6 g daily for humans.
Frequent sauna use (4–7 times per week) associated with 40% reduced all-cause mortality, 50% reduced cardiovascular death risk, and 65% reduced Alzheimer's risk in 20-year prospective study of 2,315 men. Mechanism involves cardiovascular stress response: heart rate elevation to 100–150 bpm, vasodilation, heat shock protein production, and protein refold capacity. Standard protocol: 80–100°C for 15–20 minutes, 3–7 times weekly with 3–5 minute cool-down between rounds.
42% of American adults and >70% of northern latitude residents in winter are vitamin D deficient. Vitamin D is hormone precursor regulating >1,000 genes affecting immunity, mood, testosterone, bone density. Deficiency associated with 2× all-cause mortality risk. Typical physician dose (1,000 IU) is maintenance only; deficiency below 30 ng/mL requires 5,000–10,000 IU daily for 8–12 weeks, then 4,000–5,000 IU maintenance.

Voluntary breathing techniques (Wim Hof method) trained over 4 days enabled subjects to control immune response when injected with bacterial endotoxin. The technique produces respiratory alkalosis triggering adrenaline surge that suppresses pro-inflammatory cytokines (TNF-α, IL-6, IL-8) and increases anti-inflammatory IL-10. The breathing protocol (30 deep breaths, exhale hold, inhale hold, repeat 3 rounds) takes 10–15 minutes and produces immune modulation, improved cold tolerance, and mental clarity. A Radboud University study demonstrated 50% reduction in inflammatory markers and dramatically reduced symptoms in trained practitioners versus controls.
Body Protection Compound 157 (BPC-157) is a 15-amino acid peptide naturally present in human gastric juice that accelerates healing in tendons, ligaments, muscles, gut lining, bones, teeth, corneas, and brain tissue by 3–10× depending on injury type. The mechanism is angiogenesis acceleration: BPC-157 stimulates new blood vessel formation at injury sites. Animal studies show tendon recovery in 4–8 weeks versus typical 6–12 months, gut lining repair for inflammatory bowel disease, neuroprotective effects in brain injury, and counteraction of NSAID-induced gut damage. Typical protocol: 250–500 mcg daily for 4–8 weeks, available orally or by injection.
Salt restriction causes more harm than benefit. Table salt is chemically processed and mineral-depleted; mineral-rich salts (sea salt, Redmond Real Salt, Himalayan) contain trace minerals essential for adrenal function, muscle contraction, neuron firing, stomach acid production, and hydration. The sodium-health relationship follows a J-curve; low intake is as dangerous as high intake.

Creatine supplementation is primarily marketed for muscle but has stronger evidence for brain effects. Meta-analyses show creatine improves memory and processing speed, especially in sleep-deprived, vegetarian, and older adults. Brain creatine stores deplete under stress, sleep loss, and cognitive load. Single high-dose creatine during sleep deprivation partially recovered cognitive performance and brain energy markers for ~9 hours. Vegetarians show largest cognitive gains because dietary creatine comes from meat. Protocol: 5g creatine monohydrate daily, $10/month.
Taurine declines >80% over lifetime; 60-year-olds have roughly one-third of childhood levels. 2023 research suggests this decline may drive aging, not merely reflect it. Animal studies: middle-aged mice supplemented with taurine lived 10-12% longer (~7-8 human years); middle-aged monkeys showed improved bone density, blood sugar, immune markers, and liver health. Mechanisms include reduction of cellular senescence, mitochondrial protection, calcium handling, and membrane support. Humans produce some taurine; dietary sources are meat, fish, shellfish. Production declines with age while demand stays constant, creating an 80% slide unmeasured on standard blood panels.

Author reports that female rats take more cocaine than males and that progesterone reduces cocaine use in females in some contexts. A quoted excerpt says progesterone alone reduced reinstatement only in females, while progesterone plus atomoxetine reduced it in both sexes.
Author makes a sarcastic or rhetorical statement about believing something found on the internet regardless of fact checkers, with an attached image. No health content is visible in the retrieved text.
Author states that hypothyroidism damages the thymus, which develops and regulates the immune system, builds defense against pathogens and prevents autoimmunity by removing self-reactive T cells.
Author quotes study text saying topically applied oil can be absorbed in neonates, is probably available for nutritional purposes, and can shift the fatty acid profiles of massaged babies. A shared zarathepirate post anecdotally reports coconut oil massages for a newborn with fantastic weight gain.
The parent post contains only a link, with no retrieved commentary from the author. The quoted account (DiscoOrpheus) asserts that vocal-cord frequencies affect matter, water, relationships, hormones, memory, brainwaves, the CNS and electromagnetic fields.
The author claims coffee protects muscle and strength. They cite mouse findings of larger hind limbs, better muscle regeneration, more proliferating satellite cells and greater grip strength in aged mice, and call grip strength a predictor of longevity in humans.
lowmegatron claims coffee reduces muscle breakdown by inhibiting 11β-HSD1, which he says increases cortisol locally and breaks down muscle.
lowmegatron reports a study finding that drinking 2 or more cups of coffee per day was associated with a 72% lower risk of low muscle mass. The figures are 38% lower for 1–3 cups/week, 47% for 4–6 cups/week, and 72% for 2 or more cups/day, compared with under one cup/week.
lowmegatron says a study linked coffee, caffeinated coffee and caffeine intake to higher ASMBMI (limb muscle mass adjusted for BMI). He explains the measure and quotes the authors suggesting that higher intake may be advocated for people at high risk of low skeletal muscle mass.
The author describes a low-carb pattern of weight loss, then weight gain, more restriction and hypothyroid symptoms. They claim high local cortisol can suppress thyroid hormone action while labs look normal. The quoted account (MojitoSlammer) reports going from 40% to 30% body fat without peptides or strict dieting, crediting Ray Peat.
The author asserts that depression is a brain energy problem, not a low serotonin problem. They quote press reporting on a review article that says serotonin appears to be released and used more, not less, during depressive episodes, and suggest antidepressants may obstruct recovery. The quoted account (Babygravy9) gives an anecdote about a friend on antidepressants for twenty years.
The post contains only a link and a quoted post from lowmegatron that itself consists only of a link; no health content is retrievable.
Author asserts that thyroid hormone regulates energy and that energy determines everything. The quoted post, from another account, is an anecdote that the user became less prone to sickness after starting thyroid supplementation.
Author claims stearic acid limits the cancer-promoting effects of seed oils. Support cited is rat and mouse abstracts in which stearic acid reduced or delayed tumours and lowered linoleic acid in tissues. The author also notes centenarians' fondness for chocolate. The quoted post from another account claims polyunsaturated fats are required for skin cancer and saturated fat protected mice.
Author posts excerpts from an older study on oral serotonin given in capsules or as bananas to human subjects. Platelet serotonin rose 2.5 to 6 times over 18 days of up to 160 mg/day, and plasma and urinary markers returned to normal within 48 hours of stopping. The authors predict high-banana-intake populations have raised platelet serotonin. The quoted HansAmato post says avoiding kiwi, tomato and banana because of serotonin is mistaken, as serotonin is broken down in the gut.
Author claims poor glymphatic drainage causes depression and dementia, and that low-dose alcohol improves glymphatic clearance while heavy drinking is worst. The pasted mouse study excerpt found 0.5 g/kg improved glymphatic function, while 1.5 g/kg and 4 g/kg reduced it. The quoted Outdoctrination post says glymphatic dysfunction drives depression.
lowmegatron promotes his Hypothyroid Masterclass course, which he says teaches practical testing, nutrition and dosing concepts and includes a support community.
The author claims coffee, including decaf, lowers blood endotoxin by strengthening the gut barrier. They say high endotoxin drives many chronic conditions and quote a rodent finding on decaf and endotoxin translocation. The embedded post from lowmegatron says caffeine reduces endotoxin-induced brain inflammation in rats.
The author claims vitamin E can ease asthma by blocking harmful byproducts formed when polyunsaturated fats interact with bacterial endotoxin. They say it acts on the same pathways as some asthma drugs.
The author says T3 thyroid hormone raised brain energy and reduced depression in some patients, describing a study of 19 patients with treatment-resistant depression. The quoted results link the antidepressant response to increased brain ATP and decreased PCr. The embedded lowmegatron post argues depression is a brain energy problem rather than low serotonin.
The post quotes Ray Peat saying that in the 1930s thyroid removal raised blood cholesterol and thyroid supplementation lowered it. He says thyroid promotes conversion of cholesterol to pregnenolone and progesterone. The embedded metabolicwave post is a Ray Peat clip on the cholesterol-lowering effect of thyroid.
The author reports that in women with Hashimoto's taking levothyroxine, one year of 2,000 IU/day vitamin D lowered TPO antibodies by about 30% and TgAb by about 25%. They were not vitamin D deficient at the start. The embedded post quotes Ray Peat on TSH, prolactin, calcium and vitamin D.
The post quotes Ray Peat saying that extreme serotonin overproduction tends to produce a hibernating state. He describes its purpose as keeping the machinery running while shutting down expensive biological processes.
The author makes a sarcastic analogy about shooting everyone, running an RCT and dismissing contrary evidence when bullets show no mortality effect. The embedded Outdoctrination post says you don't need a large RCT to know being shot kills. No specific health topic is discussed.
The post quotes Ray Peat saying alcohol served to him acted as an antidote to allergens that would otherwise make him sick, with antioxidant effect he compares to vitamin E. The embedded lowmegatron post claims low-dose alcohol increases glymphatic drainage in mice and that light drinkers have lower depression and dementia risk.
A bracketed question about Armour thyroid is followed by a quoted joking answer about once buying a barrel of the powder and finding it very good. It is followed by laughing emojis.
Author claims bacterial endotoxin drives cognitive impairment and that vitamin C deficiency worsens gut barrier integrity and endotoxin handling. Vitamin C is said to help protect against endotoxin effects, including in mice. The author also says vitamin C supports vitamin E recycling and lowers lipid peroxidation from polyunsaturated fats.
Quoted Ray Peat passage argues diabetes is driven by stress-induced free fatty acids that block glucose oxidation, not by sugar. He says this impairs thyroid hormone activation and that free fatty acids kill newly regenerated pancreatic beta cells.
lowmegatron claims low T3 decreases glucose oxidation and sugar use and raises cortisol and glucagon. He says this increases reliance on fatty acid oxidation and raises free fatty acids, and that high TSH also increases free fatty acids.
lowmegatron claims elevated free fatty acids compete with glucose oxidation (the Randle cycle) and impair insulin signaling. He says this creates a cycle of insulin resistance and more fatty acid reliance, and that elevated fatty acids can damage pancreatic beta cells. The quoted post attributes elevated free fatty acids to "fat loss" diets and links them to cancer, T2D, obesity and fatty liver.
Author advertises a thyroid masterclass with video lessons and a support community, covering hormones, tests, diet, supplements and lifestyle. It is pitched as focusing on proper testing, hidden hypothyroidism and causes of thyroid hormone suppression.
Author argues thyroid hormone T3 is a key determinant of heart rate and that overtraining and stress lower T3 while raising T4 and lowering TSH, making it easy to overlook. Stress-induced free fatty acids are said to block thyroid hormone metabolism and reduce the sensitivity of blood tests. The author says exercise should build you up rather than break you down.
Post text is only a t.co link, with an embedded post by pikeypilled saying 'Peaters getting access to research chemicals'. There is no substantive health content in retrieved text and no author comment.
Author says Japan has significantly lower seed oil consumption, primarily using canola rather than soybean oil, which is much higher in linoleic acid. This is posted in reply to a quoted Bryan Johnson question about Japan's higher centenarian rate.
lowmegatron posts only a link. The quoted post by jeffnobbs argues that Japan's longevity does not show seed oils are fine, because Japan consumes less seed oil, uses canola (lower in omega-6) rather than soybean oil, eats more omega-3, and does not allow TBHQ in cooking oils. It also says Japan's obesity has risen alongside seed oil use while calories stayed flat.
Author presents a causal chain in which hypothyroidism lowers glucose oxidation and raises cortisol and glucagon. Free fatty acids then block glucose oxidation (Randle cycle), producing 'insulin resistance', and they kill pancreatic beta cells, causing type 2 diabetes. The author says hypothyroidism doubles the risk of type 2 diabetes.
Author says sugar or protein can reduce leaky gut and endotoxin absorption during stress, but only sugar does so without GI problems. A quoted abstract on exertional-heat stress says glucose and hydrolysed whey protein reduce intestinal injury and permeability compared with water, while protein increases GI symptoms.
Author says winter's lower light and cold-stress free fatty acids suppress thyroid activity. Quoted Ray Peat passages say thyroid supplement needs can be four times higher in December than July, and recommend bright incandescent or full-spectrum light and limiting unsaturated fats and tryptophan.
Author claims that higher TSH within the normal range raises the risk of developing hypertension, more so in men than in women. The author attributes this to low thyroid hormone raising stress hormones, which raise blood pressure. The author also calls 'euthyroid' a poor marker of thyroid hormone status.
Author states that taste and smell disturbances affect about 80% of hypothyroid patients and usually reverse with proper treatment. A long quoted passage from an unnamed clinical paper says taste defects may help explain reduced food intake in hypothyroidism. It also says the disturbances generally improved after thyroid hormone replacement.
Author claims linoleic acid, abundant in seed oils, is elevated in the blood in migraine and is raised further by hypoglycemia. The author proposes that linoleic acid raises PGE2, causing vasodilation, greater pain sensitivity and migraine. The author also says it raises serotonin, another trigger.
Author claims bacterial endotoxin reduces empathy in women, citing an experiment where injected endotoxin lowered empathy for others' psychological pain versus placebo. The experimenters suggested this may be an energy-saving adaptation. The author adds that endotoxin disrupts energy production, thyroid hormone and glucose metabolism, and quotes Ray Peat on intestinal endotoxin. The author notes the experiment used women only.
Author advises that what is not fit to eat should not be applied to the skin, citing a quoted study finding that topically applied oil can be absorbed in neonates and is probably available for nutritional purposes. The embedded quoted post says fatty acids from oils rubbed into the skin appear in triglycerides, with safflower and coconut oil changing the fatty acid profiles of massaged babies.
Post shares a Ray Peat quote saying low thyroid is accompanied by extra antibody production, including antibodies to the thyroid itself, as part of a cleanup process. Per the quote, antibody production stops when inflammation stops, and circulating antibodies take several months to disappear. The embedded quoted post (lowmegatron) gives a longer Ray Peat excerpt on Hashimoto's, iodine, TSH and antibodies.
The author says thyroid hormones, specifically levothyroxine, help lower Hashimoto's antibodies and thyroid inflammation. Excerpts from three named papers are quoted in support. The author adds that levothyroxine plus TSH testing is usually not the best approach and that treatment focused on T3 activity will likely work even better.
The post shares a Ray Peat quote linking migraine to hypothyroidism, high serotonin, and intestinal irritation. In the quote, active thyroid hormone (T3) lowers serotonin and T3 is effective against migraines at the right dose. The embedded quoted post (lowmegatron) says linoleic acid from seed oils is elevated in migraine and raises PGE2 and serotonin.
The post says JFK was diagnosed hypothyroid in 1955 and used T3-only treatment. It quotes medical-history sources and describes basal metabolic rate (BMR) testing as avoiding pitfalls of thyroid/TSH blood tests. It also quotes Werner and Ingbar and Broda Barnes on BMR and basal temperature testing. The embedded post (lowmegatron) discusses an FDA intent to ban natural desiccated thyroid (NDT) and NDT composition.
The author says cocoa supports gut barrier integrity and lowers circulating endotoxin. The author lists conditions attributed to high endotoxin and quotes a finding of a 40% reduction in plasma endotoxin. The author advises choosing cocoa low in heavy metals. A PMCID is cited with a mouse emoji. The embedded post (lowmegatron) says metabolic endotoxemia causes obesity and diabetes in mice and humans.
The sharing account reposts an excerpt from a quoted user's account of starting Armour thyroid and then T3. The quoted user reports warmer body temperature, more energy, and relief from anxiety, ADHD, paranoia, depression and brain fog.

The author answers Ricky Gervais's question about staying fat and exhausted despite daily exercise. They attribute it to over-exercising reducing T3 conversion and raising free fatty acids, which they say lowers metabolic rate and makes weight loss harder.
An excerpt from Kathleen Stewart's Substack email exchange with Ray Peat. The writer describes true hypoglycemia and suspected glucuronidation problems, and Peat replies that these are all signs of hypothyroidism and that a thyroid product lacking thyroid tissue may not raise temperature and pulse.
The author cites a finding that hip fracture risk doubles in men with subclinical hypothyroidism, defined as high TSH with free T4 in range. The author criticizes the definition for ignoring T3 and calls the concept of subclinical hypothyroidism 'insane'.
The author states that high TSH, and higher 'normal' TSH, increases miscarriage risk. The post quotes Ray Peat on elevated estrogen in hypothyroidism and thyroid's role in fertility, and quotes a study (PMID 31525729) linking TSH of 2.5-4.8, and above 4.8, to miscarriage.
The author claims endotoxin causes depression and anhedonia. The post quotes an experimental inflammatory challenge study (PMID 20719303) and a study reporting an anhedonia-related effect in women but not men (PMID 31103547). The embedded post from lowmegatron claims endotoxin reduces empathy in women and quotes Ray Peat on endotoxin and energy production.
The author shares a Ray Peat quote about animals, ants and birds behaving intelligently and communicatively. The embedded post shows a bird and golf balls, with no health content.
The post quotes Ray Peat recalling childhood migraines, myopia and apparent hypothyroidism among nearsighted girls. The embedded lowmegatron post quotes Peat on serotonin, thyroid hormone, intestinal inflammation and migraine.
The author summarizes a small 2011 Brazilian pilot study (PMID 20662037) of near-infrared low-level light therapy on the thyroid in chronic autoimmune thyroiditis or Hashimoto's. The reported outcomes were reduced T4 needs, some patients stopping medication, lower TPOAb, and some normalized thyroid vascularization. The author also explains vascularization and the relationship between CAT and Hashimoto's.
Author reports that near-infrared light therapy in Hashimoto's patients was followed by lower T4 requirements, lower TPOAb and higher thyroid echogenicity. The post describes it as a follow-up to a pilot study and gives the light parameters and session schedule.
Author says light therapy improved thyroid parenchymal vascularization in Hashimoto's (chronic autoimmune thyroiditis), possibly through reduced autoimmunity. The post quotes the Brazilian researchers and gives vascularization figures for treatment vs placebo.
Author reports a 6-year follow-up of a human RCT in which levothyroxine/T4 requirements stayed reduced in the light-therapy group vs placebo. Author says no long-term risk was found, but that things worsened after treatment stopped.
Author says light therapy plus supplements beat supplements alone in a Turkish human study of Hashimoto's, with higher T3, higher T3/T4 ratio, lower TPOAb and lower L-thyroxin dose. The post gives the laser protocol and comments on the supplements used.
Author reports a Kosovo study in which three weeks of near-infrared light therapy added to selenium/vitamin D was followed by improved thyroid labs and reduced weight and waist measures in Hashimoto's. The post gives the light parameters and says weight fell further at 6 months.
Post shares Ray Peat quotes saying T2 works practically like T3, and that digesting desiccated thyroid product releases T4, T3 and some T2. The quoted post from texugodum3l says 'T3 is not the end my fellow peaters'.
Author reports a Kosovan study in which three weeks of near-infrared light therapy plus supplements was followed by lower thyroid volume and improved thyroid labs in Hashimoto's. The post says the share of patients with normal thyroid volume rose from 17% to 96% at 6 months.
Author says coffee rapidly lowers prolactin and quotes a study passage stating prolactin concentrations significantly decreased after consumption.
Author states that B1 and B2 are essential for estrogen detoxification and quotes passages saying deficiency of either aborts estradiol inactivation in the liver.
Post shares a Ray Peat quote saying penetrating red light is possibly the fundamental anti-stress factor and that chronic deficiency of it may best explain aging-related deterioration. The embedded older post from lowmegatron quotes Peat on red light and stress-related electron displacement.
Author cites a case-control study abstract reporting about 2x thyroid cancer risk associated with dental X-rays, and adds a sarcastic remark that X-rays were once called safe and are now safer because doses are lower. The quoted post relays Ray Peat's views on avoiding unnecessary X-rays and on nutrients, hormones, coffee and red light as protective around X-rays.
Author claims light is the most effective treatment for Hashimoto's, listing improvements including lower TSH, antibodies and inflammation, and says 47% no longer needed thyroid medication, if done correctly. Says research will follow in a thread.
lowmegatron reports a 2010 pilot study of light therapy in Hashimoto's-related hypothyroidism. He cites a 60% reduction in T4 needs, 47% discontinuing medication, a 40% drop in TPOAb, and normal thyroid vascularization in a quarter of participants, with two sessions per week for 5 weeks.
lowmegatron says a follow-up RCT confirmed and expanded the pilot results. He reports 47% stopping thyroid medication, a 58% average reduction in T4 needs, a 49% drop in TPOAb, 95% reducing T4, and 95% increased echogenicity, which he interprets as healthier thyroid tissue.
lowmegatron says levothyroxine/T4 needs stayed lower for years after light therapy compared with placebo, but that medication requirements crept back up over time, so it is "not a one-and-done."
lowmegatron claims light therapy outperformed selenium, vitamin D and iron in Hashimoto's. He reports T3 up 54%, T3/T4 ratio up 44%, TPOAb down 73%, and T4 needs down 50%.
lowmegatron says light therapy led to weight loss that continued for months without further treatment. He reports weight down 6.8%, waist down 6.9%, hip down 3.0%, and waist/hip ratio down 3.3%.
lowmegatron says light therapy reduced thyroid volume in Hashimoto's and reads this as a marker of healing and less inflammation. He reports that 4× more people reached normal thyroid volume after treatment.
lowmegatron describes Hashimoto's as lymphocytes invading the thyroid, which causes inflammation and increased vascularization. He says light therapy reverses this vascularization and treats that as another sign of healing.
lowmegatron recounts his own past attempts at thyroid light therapy. He ran two tests with two lights, dosed twice weekly for 3 months each, and antibodies stayed high. He suggests one light was red and one was too strong.
lowmegatron states that all studies in the thread used low-power near-infrared light (820, 830 and 850 nm, 50–200 mW), not red light.
lowmegatron plans a new self-experiment with an 830 nm near-infrared device placed a few inches from the thyroid, a few minutes a day, 3 times a week, to see whether his antibodies change. He claims most suppliers misstate device specifications and names Redlightman and Gembared as the only trustworthy ones. He asks readers to share their results and dosing details.
The post text is only a link, sharing the author's earlier post on light and Hashimoto's. No added commentary or endorsement is visible.
Author calls something the 'most unexpected sleep aid'; the item is not identified in the text and is presumably in the attached media or link.
lowmegatron promotes his Hypothyroid Masterclass, a video course with a support community. It covers hypothyroidism, blood tests, autoimmunity, T3 conversion, supplementing T4, NDT or T3, nutrition, iron, iodine and selenium, PUFA, stress and drugs affecting thyroid hormones.
Author says high coffee intake is associated with lower melanoma risk (20% lower at 4+ cups/day), and proposes that caffeine inhibits lipid peroxidation, which they link to PUFAs, seed oils and skin cancer initiation. The quoted post says coffee rapidly lowers prolactin.
Post quotes Ray Peat answering a question on urticaria angioedema: mast cell activation by low blood sugar and irritants, releasing histamine and serotonin and causing edema.
lowmegatron says the preceding content can be read as an article and links to it. The linked page and the attached media content are not visible.
Author claims seasonal thyroid sluggishness is driven by light, with NIRA infrared 5-10x higher in summer than winter at ~50°N, the same range said to help in Hashimoto's, and that most true hypothyroidism is Hashimoto's.
Post quotes Ray Peat on hives triggered by cold, exercise or low blood sugar, describing a chain of impaired oxidative metabolism, lactic acid, lipolysis and PUFA-derived prostaglandins, and recommends small frequent meals. The author adds mechanistic commentary on cytochrome c oxidase, mast cells, PUFAs, CO2 as mast-cell stabilizer, and T3.
Author reports that Kuinone, described as topical vitamin K2 MK-4, turned their sleep around. It is quoted alongside their earlier 'most unexpected sleep aid' post.
Author lists proposed antidepressant mechanisms of coffee. The embedded lowmegatron post says coffee intake is associated with lower melanoma risk and attributes skin cancer to lipid peroxidation of PUFAs from seed oils, pork and poultry fat rather than sun.
Author posts a checklist of factors for thyroid hormone T3: carbohydrates, calories, several vitamins and minerals, low stress, and moderate protein.
Author says aspirin may prevent colorectal cancer by improving gut microbiota, quoting a paper abstract. The embedded quoted post relays an anecdote about actor Matthew McConaughey's mother beating two cancers 'on aspirin'.
Author reports receiving a device and completing a first test of 2 minutes on each side of the thyroid at 1.5 inches. They plan to increase to 8 minutes per side every other day.
Author quotes a study suggesting part of coffee's anti-diabetic effect is inhibition of 11β-HSD1 glucocorticoid reactivation. The author explains that 11β-HSD1 converts cortisone to cortisol, promoting insulin resistance, glucose production and visceral fat.
Author argues coffee metabolites are linked to lower type 2 diabetes risk, and that coffee compounds may act via cortisol lowering and 11β-HSD1 inhibition. One quoted study found an association with filter coffee but not boiled coffee.
Author shares a Ray Peat passage claiming bright artificial light can replace sunlight against the stress reaction, with longer days healthier and brief intense light exposures possibly protective. The embedded quoted post is another Ray Peat quote on red light as an anti-stress factor.
Author writes 'We have to go back' with attached media, which is not transcribed. The quoted post by AbudBakri predicts someone will create an outdoor healing retreat with this type of experience.
lowmegatron reports an update on his self-experiment: he is now at 4 minutes each side of the thyroid and sees no reaction. The quoted post says the device arrived, he began at 2 minutes per side at 1.5 inches, and he plans to work up to 8 minutes every other day.
Author presents mouse-study excerpts on Coca-Cola and Pepsi, reporting larger testes, higher serum testosterone and increased androgen receptor mRNA expression. The embedded quoted post links omega-6 intake to smaller testicles in young Spanish men.
Author states treatment-resistant depression occurs when its cause is not treated, quoting a case report of a woman whose mood and cognition improved with T3 liothyronine. The embedded quoted post from EndoMedChem summarizes the same case.
The author lists substances and practices that he claims lower or block serotonin, including aspirin, L-theanine, thiamine, glycine, taurine, T3, ginger, cyproheptadine, vitamin E, magnesium, DHEA, progesterone, testosterone/DHT, lysine, and avoiding seed oils. The quoted context is a Ray Peat line about serotonin overproduction and hibernation.
The author states that depression risk falls 8% per cup of coffee, begins to decrease at 68 mg caffeine/day, and keeps falling up to 500 mg/day, citing PMID 26339067. The embedded quoted post lists proposed antidepressant mechanisms of coffee.
The author claims hypothyroidism activates the sympathetic nervous system, raising cortisol (+60%), adrenaline, noradrenaline and aldosterone (doubled), with downstream effects on blood pressure, blood sugar and mood. Thyroid hormone replacement reversed the activation and lowered diastolic blood pressure, citing PMID 11994331.
The post shares a Ray Peat excerpt claiming carrageenan is an allergen and inflammatory laboratory material. Peat reports avoiding carrageenan-containing foods because of allergic symptoms and asserts it may appear unlisted in foods. He says regulators ignore interaction with gut bacteria and absorption by 'persorption'.
The parent text only says '@CowsEatGrassBlg talks about this'. The embedded quoted post from lowmegatron cites a mouse study reporting that Coca-Cola and Pepsi increased testis mass, serum testosterone and androgen receptor mRNA expression.
The author posts 'Winter is coming.' with an image, quoting a post that asks whether more thyroid hormone is needed in winter and requests shares for numbers. No substantive health claim is made.
The author asks how Ray Peat would address insulin resistance and early type 2 diabetes, then shares a Peat excerpt. Peat claims chronic stress and estrogen raise free fatty acids, which interfere with glucose use, and that lowering stress and estrogen improves insulin sensitivity and glucose-to-CO2 conversion rather than lactic acid.
The author claims subclinical hypothyroidism is linked to a 2x increase in diabetes and that ignoring active T3 makes the diagnosis flawed. The post proposes that low T3 shifts to fatty-acid oxidation, raising free fatty acids and causing insulin resistance. It cites mouse experiments and PMID 31156553, with an NHANES reanalysis quoted. The embedded post is a Ray Peat quote on insulin resistance.
The author promotes the Hypothyroid Masterclass, a video course with a support community, aimed at people whose thyroid labs are 'normal' but who feel hypothyroid. The post lists the course modules. The quoted post is only a link.
The author argues that standard hypothyroidism treatment suppresses TSH without relieving symptoms and produces misleading blood tests. They support this with a quoted passage from a paper saying many patients need T4 doses that lower or suppress TSH to restore T3 levels and clinical euthyroidism. The embedded quoted post from lowmegatron says TSH/T4 tests can miss downstream thyroid hormone problems.
The author calls the embedded quoted post their most popular reply. The quoted post, by goodcharls, says 'Food Scientists should be crucified'. There is no health content in the visible text.
The post quotes Ray Peat saying the skin test for iodine deficiency is unscientific because reductants convert iodine to colorless iodide. The embedded quoted post from lowmegatron quotes text linking excess iodide to autoimmune thyroiditis and adds a bracketed comment about selenium, vitamins C and E, and polyunsaturated fats.
The author claims stress, defined as energy demand exceeding supply, slows metabolic rate through effects on thyroid hormones, causing 'hidden hypothyroidism' that blood tests often miss. The post appears to open a thread.
lowmegatron defines stress as not only psychological, citing Hans Selye's definition: "The nonspecific response of the body to any demand placed upon it."
lowmegatron lists his markers of stress: raised cortisol, glucagon, adrenaline, prolactin, serotonin, growth hormone, free fatty acids, reverse T3 and fat gain, with lower muscle.
lowmegatron argues that hypothyroidism is reduced thyroid gland output, but symptoms come from low T3, the active hormone. He says problems after the hormones leave the gland can still cause hypothyroid symptoms, which he calls hidden hypothyroidism.
lowmegatron says TSH is the most common hypothyroidism test and is assumed to be good when low and bad when high. He claims stress also lowers TSH, so it is unreliable as a marker of thyroid hormone activity.
lowmegatron says T4 is the storage form and the next most common test. Low T4 can indicate a thyroid problem, but normal T4 does not confirm good activity because T4 must convert to T3, and he says conversion declines under stress.
lowmegatron claims good T3 lab results do not guarantee optimal thyroid activity because labs only measure blood. T3 must enter tissues and cells and activate receptors, and he says stress disrupts every step.
lowmegatron claims stress hormones lower T4-to-T3 conversion and TSH and raise free fatty acids. He says PUFAs in those free fatty acids block T3/T4 uptake and receptor binding, and that PUFAs come mainly from seed oils, pork and poultry. He concludes cells become T3-starved even when blood tests look normal.
lowmegatron lists what he presents as indicators of low cellular thyroid activity: feeling cold, high reverse T3, high reverse T3:T3 ratio, hypothyroid symptoms, low resting metabolic rate, and low waking basal temperature.
lowmegatron lists what he calls common causes of stress: fasting, poor sleep, undereating, over-exercising, psychological stress, and low carbohydrate intake. He says it is often a combination, and that many people pair malnutrition with over-exercising.
The post quotes Ray Peat recalling Hungarian data on hundreds of thousands of women, in which lifespan rose with number of babies up to eight. He attributes this to residual higher progesterone offsetting the pro-aging effects of estrogen.
The post quotes Ray Peat describing people with extreme hypothyroidism who oscillated between depression and mania. In his account, temperature was low during depression, and pulse and temperature were at Broda Barnes' target in mania.
The post contains only a link. The embedded quoted post from ValtsuH says an old blog post has additional references, in reply to lowmegatron.
The author announces that their course on low thyroid is live, offering video lessons and a support community. It is described as covering hormones, tests, diet, supplements and lifestyle, with a focus on proper testing, hidden hypothyroidism and causes of thyroid hormone suppression.
The author reports a self-experiment applying a device to each side of the thyroid for up to 8 minutes at about 1.5 inches, planning 2-3 times per week and an antibody recheck in 4-6 weeks. The embedded earlier post from lowmegatron describes the device arriving and a first 2-minute session per side.
The author says aromatase inhibitors regenerate the thymus by reducing testosterone-to-estrogen conversion. They support this with a quoted passage on aging rats, which notes that testosterone alone probably does not explain age-related thymic atrophy. An embedded post by lowmegatron claims hypothyroidism shrinks the thymus and impairs immune function.
The author shares signs of stress that can indicate low thyroid hormone activity, but the signs themselves are not in the retrieved text. The embedded lowmegatron post claims stress causes hidden hypothyroidism, slows metabolic rate via thyroid hormones, and often goes undetected in blood tests.
The author quotes a 1967 J Clin Endocrinol paper reporting decreased stage 3 and 4 sleep in hypothyroidism, with an increase after desiccated thyroid treatment in four of seven patients re-studied. The embedded post by MichaelLexner is an n=1 anecdote about taking T3 before bed and not waking to urinate.
The author claims cocoa supplementation lowers inflammatory markers of aging and cardiovascular disease, largely via gut barrier effects and lower endotoxin. They quote a trial abstract on hsCRP and the COSMOS trial's 27% cardiovascular death reduction. The embedded post by lowmegatron links endotoxin to many conditions and advises choosing cocoa low in heavy metals.
The author promotes oysters for immunity on the claim that age-related relative zinc deficiency lowers immunity and that zinc acts as an aromatase inhibitor, which blocks estrogen-driven thymus loss. They quote two rodent-marked passages on zinc supplementation and estradiol-induced thymus shrinkage. The embedded post is lowmegatron's aromatase-inhibitor and thymus post.
The author criticizes hospital total parenteral nutrition for including seed-oil-derived linoleic acid, which they say was used for immunosuppression in transplants. They say it could supply 20-60% of calories and that fish oil replacement is not a good idea. The embedded post quotes Ray Peat on fish oil and immunity.
The post is a quotation from Broda Barnes stating that thyroid deficiency is among the causes of infertility, citing thyroidectomized animals that lack reproductive power and his own cretinized swine that never came into detectable estrus.
Author describes a study in which depressed participants were warmed with infrared lights to 101°F, then slowly cooled. Hamilton depression scores reportedly improved by about 6 points, and by about 10 points for some a few weeks later. The embedded post is a Ray Peat quote linking low temperature in hypothyroidism to depression and higher temperature to mania.
Ray Peat quote recounting second-hand anecdotes that children born to mothers given progesterone did precocious things, including a four-year-old's notebook story.
Author presents a graph of symptom-questionnaire scores for people switched from levothyroxine/T4 to natural desiccated thyroid (NDT), reporting 90% improved, 6% unchanged and 3% deteriorated. Author claims levo/T4 suppresses TSH but often leaves T3 inadequate, and that NDT's benefit is due to its T3. Quotes a paper noting NDT's potential benefit in selected symptomatic patients after careful consideration.
Author asserts that standard tests miss a lot in people with slow metabolism and 'normal' thyroid labs, that levothyroxine rarely restores active thyroid hormone, and that hormone conversion is often ignored. Promotes their hypothyroidism video course and community.
Author shares patient testimonials, attributed to PMID 38260143, describing improvements in mood, sleep, energy, focus and daily function after switching from levothyroxine to NDT, with several patients reporting severe symptoms on levothyroxine. One patient notes a sweet spot between too little and too much NDT.
Ray Peat quote claims hypothyroid people do not reach deep restorative sleep, and the post adds a 1967 EEG study abstract reporting reduced stage 3 and 4 sleep in 7 hypothyroid patients, with an increase after desiccated thyroid therapy in 4 of them.
Brief social remark addressed to 'progesterone ladies' introducing 'Kozyrev Mirror Guy'; meaning is not explained in the retrieved text.
Ray Peat quote says plain water is never drunk and that making drip-method coffee with city water is a practical way to filter it, because heavy metals bind to the coffee grounds.
The author shares a patient report of improvement after switching from levothyroxine to NDT, including clearer eczema, no more hair loss, and less fatigue, dry skin and constipation. He claims NDT's effects differ from levothyroxine because of its T3 content, and that people who don't recover on levothyroxine can't make enough T3 from it.
Author claims cortisol shrinks the thymus, lowering protective immunity and raising autoimmunity risk, with changes resembling aging, citing a quoted finding on lymphocyte loss after cortisol injection. The embedded post (lowmegatron) argues zinc, from sources like oysters, may protect the thymus and estrogen shrinks it.
The author lists supplements, foods and habits they say protect against polyunsaturated fat (PUFA) and seed oil effects. The lists cover reducing lipid peroxidation, lowering free fatty acids and supporting glucuronidation and sulfation. The author also advises eating mostly saturated fats and avoiding high-PUFA oils. The embedded lowmegatron post has an overlapping saturated fat/PUFA list plus a note on olive oil.
The author states that blocking the glucocorticoid receptor lowers glucose and insulin in obese, diabetic mice, and that receptor activation raises free fatty acids. They list interventions said to help lower cortisol. The embedded lowmegatron post quotes a suggestion that coffee's anti-diabetic effect involves inhibiting 11β-HSD1.
The author quotes Ray Peat claiming menopause symptoms are essentially identical to those of excess cortisol or Cushing's syndrome. The symptoms listed include facial hair, loss of head hair, weight gain, raised blood pressure, unstable blood sugar, fragile skin and digestive instability.
A Ray Peat quotation says inadequate deep sleep impairs tissue repair, and that thyroid hormone and vitamin D are key for maintaining deep sleep. The embedded lowmegatron post adds Peat's claim about hypothyroid sleep and a 1967 EEG study of 7 hypothyroid patients showing reduced stage 3 and 4 sleep, which increased after desiccated thyroid in 4 patients.
The author posts only the phrase 'Aromatase inhibition?' quoting another user's 'AI will cure cancer.' Its meaning is unclear without context.
The author argues red light effects depend on dose, that more is not better, and that the Sun generally cannot substitute. They cite a passage on biphasic dose response (Arndt-Schulz curve). The quoted user shares a general view that effects are dose dependent.
A Ray Peat quotation claims caffeine is strongly anti-carcinogenic in animal studies, that heavy coffee drinkers are healthier with lower rates of several diseases, and that burnt coffee is not ideal. The embedded lowmegatron post reports a meta-analysis associating four more cups of coffee daily with lower endometrial and postmenopausal cancer risk.
The author says zinc helps regenerate the aging thymus and that zinc supplements reduce infection in older people, who tend to be low in zinc, citing PMID 17344507. The author notes copper intake must be adjusted with more zinc. The embedded lowmegatron post adds oysters as a zinc source, zinc as an aromatase inhibitor, and estrogen shrinking the thymus, citing animal data.
The author claims T3 enters the brain about three times more efficiently than T4, quoting cerebrospinal fluid (CSF) percentages, and that low T4-to-T3 conversion may leave less T3 in the brain. The embedded lowmegatron post says higher T3:T4 ratios are sometimes needed for brain symptoms, quoting Ray Peat.
lowmegatron jokes that he uploaded the wrong image but it turned out to be the right one.
The author asks whether psychiatry wastes time using GABA agonist drugs for anxiety and disorders that are energetic in origin. A Ray Peat quotation replies they can be useful for a day or two for rest. The embedded lowmegatron post quotes Peat linking schizophrenia to stress, hypothyroidism, estrogen/serotonin, lipid peroxidation and low energy metabolism.
Author explains that the heart's energy comes mainly from oxidative metabolism, which they say depends on thyroid hormone T3. They state that cardiac work (Stroke Work Index) is lower in hypothyroidism and improves with thyroid hormone replacement, and quote a passage attributed to PMID 10843159. The embedded quoted post by lowmegatron links T3 to heart rate and says overtraining and stress lower T3 or its conversion.
Author announces their thyroid course, with video lessons and a support community, covering hormones, tests, diet, supplements and lifestyle. They say it focuses on proper testing, hidden hypothyroidism and causes of thyroid hormone suppression. No substantive health explanation is given.
Author links CFS/ME to low thyroid hormone activity. They share a testimonial from Paul Robinson (recovery with T3 after being dismissed or misdiagnosed) and a quoted study excerpt reporting lower free T3 and a shift toward rT3 in CFS. They assert that CFS can be caused by hypothyroidism and that medical ignorance of T3 leads to misdiagnosis, while adding that CFS likely has multiple causes.
The author's post contains only a link with no retrievable text. The embedded quoted post by Swin_Deep says CFS/ME is real, that a thyroid association is real, and that they are a male with CFS sharing their own results via an image.
Author speculates that heavy tea/coffee consumption may signal failing energetic metabolism, that caffeine resembles T3 in some ways, and that hypoglycemia and hypothyroidism are bidirectionally related. They propose that in these states lipolysis and free fatty acids rise and interfere with thyroid hormone metabolism, which labs may not flag, and that some fibromyalgia doses would be dangerous without thyroid hormone resistance. The quoted Live_eyes2025 post is an anecdote about tea, coffee, sugar, hypoglycaemia and ME/CFS.
The post contains only a link. The quoted earlier post by lowmegatron, which is context and not this post's own text, claims fibromyalgia is linked to thyroid hormone resistance and argues against tricyclic antidepressants. The linked content is not visible.
The post quotes Ray Peat's account of Hans Selye's rat experiments. In that account, high-PUFA diets (linoleic acid) caused heart cell death, and adding stearic-acid-rich cocoa butter prevented it. The posting author adds that cocoa fat and beef fat are good sources of stearic acid and that seed oils are very high in linoleic acid. The embedded post, by lowmegatron, lists claimed benefits of stearic acid.
The author claims hypothyroidism shrinks the thymus, and that thymic involution attributed to aging is caused by estrogen, cortisol and low thyroid hormone. The post quotes Ray Peat and a rat study excerpt (PMID 7954684). The embedded lowmegatron post says cortisol shrinks the thymus, citing PMID 4669870.
The author claims hypothyroidism, including 'hidden' hypothyroidism with normal TSH and T4, lowers testosterone and raises prolactin in men. They say underfeeding and overtraining can downregulate T3. They describe mechanisms involving TRH, prolactin, GnRH, LH and STAR protein. The embedded lowmegatron post says stress causes hidden hypothyroidism that blood tests often miss.
The author asserts that standard thyroid tests miss low metabolism, that levothyroxine rarely restores active thyroid hormone, and that thyroid hormone conversion is often ignored. The post invites readers to buy their hypothyroidism course. The quoted lowmegatron post contains only a link.
The post lists health outcomes that 'forever chemicals' are said to cause. The embedded lowmegatron post gives the same list and adds that nonstick coating chemicals were subject of a decades-long coverup. It says the official safe daily exposure is around one hundred millionths of an ounce, and that the primary exposure risk is drinking water.
Post shares a Ray Peat interview excerpt on how he brews coffee: moistening grounds with cool water and gradually adding hotter water, with boiling water only at the end, to preserve delicate flavor molecules said to be antioxidant while still extracting caffeine. The embedded quoted post says drip coffee grounds bind heavy metals from city water.
Post quotes Ray Peat saying stress-suppressed thyroid function may not respond to synthetic T4 because stress can block T4-to-T3 conversion. The embedded post from lowmegatron claims stress causes hidden hypothyroidism that often goes undetected on blood tests.
Post quotes a clinical thyroidology article arguing hypothyroidism should be defined by insufficient tissue T3 effect, with symptoms plus FT4 and FT3 as best indicators and TSH unreliable. The embedded post from lowmegatron shares patient reports of improvement on NDT versus levothyroxine and claims about why NDT differs.
Post shares patient testimonial quotations about switching from levothyroxine to NDT, reporting more energy, motivation, clearer thinking and reduced brain fog, citing PMID 38260143. The embedded post adds further patient reports of improved mood, sleep and function on NDT versus levothyroxine.
Author states hypothyroidism can cause Raynaud's, explaining that thyroid hormone supports oxidative metabolism, raising carbon dioxide and heat, with CO2 acting as a vasodilator. It quotes a case report of a man with primary hypothyroidism whose Raynaud's symptoms disappeared after T4 replacement.
The author shares a Ray Peat quote saying carotenes are among the most dangerous supplements because they behave like polyunsaturated fats, and that tryptophan and 5-HTP directly activate inflammation. The author adds a list of common supplemental carotenoids. The embedded quoted post from lowmegatron lists titles on beta-carotene metabolites, a potential 'dark side' of high-beta-carotene diets, and beta-carotene and lung cancer.
A very short post reading 'Men eating ≤ 2500 kcal' with a link and attached media. The point cannot be understood without the missing media or linked content.
The author shares a Ray Peat quote linking low thyroid function inflammation to vitamin D deficiency. It says TSH and parathyroid hormone promote inflammatory processes, and that vitamin D, more calcium or less phosphate relative to calcium lower both hormones. A paper title on L-thyroxine and chronic urticaria is appended. The embedded post by lowmegatron says TSH/T4 tests are blind to downstream thyroid hormone issues.
The author comments that it is funny that a chatbot cited Bryan Johnson's experience inhaling high-concentration oxygen (IHHT) as an argument against CO2. The embedded Bryan Johnson post warns that CO₂ inhalation therapy carries risk, says there is no evidence it boosts metabolism or energy, and reports that his own IHHT trial raised S100-B.
The author shares excerpts from a press report on a study saying thyroid hormone coordinates brain and body to drive exploratory behavior. The author adds that scientists 'rediscover' T3's importance for mood and behavior and that its effects are opposite to serotonin's. Excerpts describe mouse experiments in which more thyroid hormone in the cortex increased exploration and risk-taking, while blocking its action removed the effect.
The author argues that subclinical hypothyroidism is not harmless: high TSH is linked to inflammation, dyslipidemia and higher cardiovascular risk. They quote passages from a paper (PMID 26674140). The embedded quoted post from lowmegatron links subclinical hypothyroidism to diabetes and insulin resistance.
The author claims alcohol combined with seed oils (corn oil) causes more liver damage than alcohol with saturated fat, via increased gut permeability and endotoxin leakage. They support this with animal studies (PMID 22150547). The embedded quoted post from lowmegatron claims coffee, including decaf, lowers blood endotoxin.
The author states that sleep restriction reduces fat loss and increases lean tissue loss during caloric restriction. They quote a study (PMID 20921542) and add that stress generally downregulates metabolism, wastes muscle and promotes fat storage. The embedded quoted post from lowmegatron lists common causes of stress.
The visible text of the post is only a t.co link, with no added commentary. It quotes bryan_johnson, who says he is getting hearing aids and claims untreated hearing loss raises risks for brain health, cognitive decline and dementia.
The post quotes text on carotenemia: in hypothyroidism it is attributed to deficient conversion of carotene to vitamin A and hypercholesterolemia. Excess dietary carotene is named as the most common cause, and other disease states and wartime plant-based diets are also mentioned. The sources are listed as titled references.
The author argues that more orange and less blue light benefits mental health and that modern bulbs strip orange, red and near-infrared light in favor of blue. An unattributed quoted passage describes manic patients wearing orange glasses in the evening and morning and improving within three days. The embedded quoted post from lowmegatron claims amber, red and near-infrared light improves age-related macular degeneration.
The post is a Ray Peat quotation, answering a bracketed interviewer question, about red and orange light reversing damage from radiation and carbon monoxide. He says Warburg worked on isolated tissues while Russians used whole animals, and that red light inactivated lethal gamma-ray effects if applied quickly.
The post advertises the Hypothyroid Masterclass, described as teaching practical testing, nutrition and dosing concepts with a support community, and lists its video modules. The embedded quoted post from lowmegatron contains only an emoji and a t.co link.
The author states insulin resistance is higher in people with lower T4, even within the normal range, quoting two papers (PMID 35385635, 17090642) that link low-normal free T4 to insulin resistance and cardiovascular risk. The embedded quoted post from lowmegatron links subclinical hypothyroidism to diabetes.
The post quotes Ray Peat recounting that Chomsky believed animals lack consciousness because they lack words, and noting that Chomsky spelled out "dog" so dogs would not get excited. It is about language and consciousness and contains no health content.
The author posts a long list of symptoms and conditions, each labeled 'Improved by CO2'. The embedded quoted post from anomalie_blue presents the list as coming from a 1958 study of 500 cases (Jackman) of CO2 treatment. That post says over 80% of patients improved and nearly 60% had complete clinical recovery.
The author states that increasing CO2 reduces migraine headaches, citing an RCT with a rebreathing device. They propose mechanisms (vasodilation, more oxygen delivery, lower CGRP) and mention thyroid hormone optimization and Buteyko breathing as other ways to retain CO2.
The author states that methylene blue inhibits MAO-A and reduces serotonin breakdown in a dose-dependent way. They say most symptoms in the quoted post align with signs of excess serotonin. The quoted user (zenovaire) describes stopping methylene blue after severe physical and psychiatric symptoms.
The author claims relaxed breathing was as effective for migraine as 80 mg propranolol, with recurrence 4 times higher in the propranolol group. The author links this to reduced hyperventilation and increased CO2 retention, and lists propranolol side effects.
The author shares a Ray Peat quote saying the therapeutic effects of increasing CO2 are increasingly recognized. It cites Buteyko for asthma and permissive hypercapnia in ventilation, while few biologists see CO2 as a universal protective factor.
The author shares a patient report of feeling better on NDT than on levothyroxine, with improved energy, sleep, skin and brain fog. He attributes the difference to NDT's added T3, which he says also helps kickstart T4 conversion.
The author shares a Ray Peat quote that thyroid hormone is the most important promoter of CO2 formation. The embedded quoted post is the author's earlier post of a Ray Peat and Bud Weiss audio talk on the biology of CO2 with a detailed topic timestamp list.
The author shares a Ray Peat quote that CO2 binds insulin and may explain thyroid effects in diabetes. The embedded quoted post from the author says subclinical hypothyroidism is associated with a 2x increase in diabetes and argues that low T3 shifts fuel use and promotes insulin resistance.
The author promotes their Hypothyroid Masterclass, described as covering the thyroid system, diseases, hormone metabolism, medications and how diet and stress can shift hormones. It includes videos and a support group. The quoted post contains only a link.
The author shares a Ray Peat quote that CO2 stabilizes the electronic balance in cells and is central to living things. The embedded quoted post repeats the author's earlier list of conditions labeled 'Improved by CO2'.
Author quotes a passage from a study titled 'All Night Sleep Studies in Hypothyroid Patients, Before and After Treatment'. The passage says stages 3 and 4 sleep are decreased in hypothyroidism and that desiccated thyroid may increase them. The embedded quoted post from lowmegatron pairs a Ray Peat quote on hypothyroid sleep quality with the full study abstract (J Clin Endor 27:1593, 1967).
Author shares a quoted excerpt, with PMID 31757552, reporting that BPA reduced T3 and T4 and raised TSH in rats with thyroid tissue damage. Ginger extract alleviated these changes, and the excerpt attributes this to antioxidant action via Nrf-2/HO-1. The embedded lowmegatron post quotes Ray Peat on environmental estrogens such as BPA altering development and DNA methylation across generations.
Author claims negative ion generators lower serotonin and histamine, and that oceans and waterfalls naturally produce negative ions. Bullets and a Ray Peat quote say positive ions raise serotonin and negative ions reduce brain serotonin and histamine. The embedded lowmegatron post lists substances and practices said to lower or block serotonin.
Post quotes Ray Peat saying the polyunsaturated fat in flax seed blocks digestive proteolytic enzymes, impairs protein digestion, inhibits the enzyme needed to form thyroid hormone, interferes with thyroid hormone transport on blood proteins, and blocks thyroid's stimulation of respiration in cells.
The posting account says seed oils raise feed efficiency (weight gain) by 20% in rats versus coconut oil. It then quotes Ray Peat, who says coconut oil is anti-obesity in animal studies and that obesity tracked the ratio of unsaturated oil to coconut oil rather than total fat. The embedded quoted post (lowmegatron) gives Peat's view that dietary polyunsaturated fats (PUFA) are anti-thyroid and drive metabolic disease.
The posting account says levothyroxine-treated patients are more likely to be depressed when TSH is above 2.5. It quotes a study that proposes 2.5 mU/L as a cut-off for depressive symptoms in T4-treated hypothyroid patients. The account adds that the brain needs enough T3, that many people convert levothyroxine to T3 poorly, and that levothyroxine can lower TSH while tissues remain starved of T3. The embedded quote describes a treatment-resistant depression case that responded to T3 (liothyronine) augmentation.
The author invites readers to join a Hypothyroid Masterclass group that has 30 videos and a support group. The post lists topics covered: the thyroid system, disorders caused by low T3, hormone metabolism, medications, and diet and stress effects.
The post quotes Ray Peat saying that 5-HTP turns to serotonin. It says Peat spoke with people with cataracts or glaucoma who had been prescribed fish oil and 5-HTP, that serotonin can create cataracts almost instantly, and that fish oils break down to increase serotonin formation in the eye. It credits an image to a 1974 Ophthalmologica paper on reversible serotonin cataract in rats. The embedded quote from lowmegatron gives a Peat quote on serotonin overproduction and hibernation.
The post quotes Ray Peat saying aerobic glycolysis, a metabolism characteristic of cancer, is promoted by serotonin. The author adds a definition of the Warburg effect. The embedded post from lowmegatron says the serotonin-blocking antihistamine cyproheptadine has anti-cancer effects and quotes case reports and cell and mouse studies with PMIDs.
Author posts a bare list of foods and habits (coffee, raw milk, maple syrup, early walk, eggs+sourdough, sunlight then red light, rice+fish, rib eye, honey, potatoes), followed by a descriptive paragraph about footballer Erling Haaland. The retained text does not state how the two parts relate.
Author states that manufactured citric acid is made from Aspergillus niger mold and quotes a case report in which a woman's joint and muscle pain, bloating and fatigue reportedly followed ingestion of foods with added citric acid and resolved after she avoided it.

Author posts the short phrase 'Protect the caffeine.' with attached media whose content is not available.
Author says optimizing zinc levels can help prevent atherosclerosis by lowering lipid peroxidation and inflammation, noting a study used 45 mg/day zinc gluconate for six months and that high zinc should be balanced with copper. The quoted lowmegatron post claims zinc supplementation regenerates the aging thymus and reduces infection in older people.
Author states that the effects of exercise can be detrimental or beneficial depending on situation, needs and goals, with an attached link and media.
Author promotes their Hypothyroid Masterclass, a 30-video course with a support group covering the thyroid system, low-thyroid diseases, hormone metabolism, thyroid medications, and diet and stress effects. The quoted lowmegatron post contains only a link.

Author posts a greeting ('GM') with a link and attached media.
The author shares a Ray Peat quotation saying that reabsorption of estrogen from a sluggish, bacteria-altered intestine (said to always occur in hypothyroidism) raises systemic estrogen and stresses the liver. Peat is quoted as saying an antibiotic or a daily raw carrot can lower estrogen and cortisol and raise progesterone. The quoted X post is a list of foods and lifestyle items followed by a Erling Haaland description.
The author quotes a statement that one medium orange a day may lower depression risk by about 20% and that the effect seems specific to citrus. The author adds that oranges lower depression risk partly by modulating gut bacteria and decreasing endotoxin.
The author says aspirin may slow fatty liver disease, quoting a prospective study in which daily aspirin use was associated with less severe NAFLD/NASH histology and lower risk of progression to advanced fibrosis. The author lists proposed mechanisms and notes that aspirin was not prescribed and that users were compared with non-users.
The post is only a thread title and link on selenium, thyroid hormones, autoimmunity and Hashimoto's. No substantive health claims are in the retrieved text.
lowmegatron claims selenium is required for thyroid hormone conversion and that a deficiency can cause hypothyroid symptoms even without a diagnosis. He also claims selenium calms autoimmune thyroid processes (Hashimoto's, Graves', thyroid eye disease) and can speed normalization of thyroid hormones during extreme stress.
lowmegatron describes a 3-month study of 70 women with Hashimoto's antibodies, all on T4. Half received 200 mcg sodium selenite daily and half a placebo. He reports normal antibodies in 25% of the selenium group versus 6% of the placebo group, and a 34% versus 12% fall in TPO antibodies. Thyroid hormones were unchanged. He calls this a '4x remission rate' and quotes the authors' conclusion.
lowmegatron describes a case study of a woman with Hashimoto's given 50-100 mcg of selenium daily for 14 months. He says 50 mcg had little effect, while 100 mcg cut TPO antibodies by 76%, and that her antibodies rose after supplementation stopped.
lowmegatron argues selenium's thyroid benefits likely come mainly from immune modulation and effects on reactive oxygen species in the gland, and says it may reduce postpartum thyroiditis. He quotes a review saying supplementation lowers anti-thyroid antibodies in Hashimoto's and in pregnant women with anti-TPO antibodies.
lowmegatron claims selenium may help autoimmune hyperthyroidism. He says patients given antioxidants including selenium alongside anti-thyroid drugs reached normal hormone levels faster, and that Graves' status correlates with blood selenium. He cites a Graves' orbitopathy trial of 200 μg/day sodium selenite with improved quality of life (over 70% vs 22%) and orbital lesions (61% vs 35%).
lowmegatron states that supplementing selenium at 500 mcg/day during acute stress, such as a surgical ICU stay, speeds recovery of normal T4 and T3 levels.
lowmegatron claims that combining selenium and myo-inositol reduces thyroid antibodies, lowers TSH and raises thyroid hormones in hypothyroid people, and that it appeared to normalize TSH in a hyperthyroid patient. He also says low selenium and myo-inositol may predispose to hypothyroidism. He gives food amounts he says supply the study doses (83 μg selenium; 600 mg myo-inositol).
lowmegatron promotes his Hypothyroid Masterclass, a course covering testing, nutrition and dosing with a support community, and lists its on-demand video modules. Modules include thyroid blood tests, T4/NDT/T3 supplementation, iodine and selenium, PUFA and FFA, and drugs that affect thyroid hormones.
The author says that six years after The Biggest Loser, participants' resting metabolic rate was 27% lower. The author argues that extreme dieting and exercise stress lower resting metabolic rate (metabolic adaptation), that chasing lower energy intake or fasting harms health, and that energy is essential for health. The embedded quoted post is an anecdote from TElizabethPhD about intermittent fasting stopping working and eating constantly after following Ray Peat's work.
The post shares a Ray Peat interview excerpt claiming that saturated fats (butter, ghee, milk) protect against or reverse alcoholic cirrhosis and hepatitis, and that animal fats reflect what the animals ate. Bracketed interviewer or poster text lists saturated and polyunsaturated fat sources and notes that linoleic acid is the main polyunsaturated fat in common seed oils.
The author cites rodent studies in which a palm oil-enriched saturated-fat diet reversed alcoholic liver injury, whereas fish oil did not improve severity. Quoted passages from the paper suggest lipid peroxidation down-regulation as a possible mechanism and call for testing in patients. A quoted post from lowmegatron adds further excerpts and PMIDs.
The author presents a severe myxoedema coma case before and after treatment. Features were hypothermia, kidney failure and TSH >100, and the patient was treated with hydrocortisone and levothyroxine and survived. The quoted case report links the multiorgan dysfunction to severe T3 depletion.
The author says 5 cups of coffee per day is associated with ~30% lower type 2 diabetes risk, quoting a pooled relative risk of 0.71 and a 6% lower risk per additional daily cup, with similar results for decaf. The embedded quoted post from lowmegatron lists proposed antidepressant mechanisms of coffee.
The author claims low magnesium can impair thyroid hormone conversion and that about half of Americans don't meet the minimum magnesium requirement.
The author says a 15-day fasting study showed T3 falling 34% and reverse T3 doubling while TSH and T4 stayed unchanged. They argue that stress lowers T3 even when common labs look fine. The post quotes study excerpts on impaired T4-to-T3 conversion and reduced rT3 clearance, and notes that Angus Barbieri died aged 51. The embedded post, by lowmegatron, says metabolic rate drops after extreme dieting.
The post quotes Ray Peat saying high-dose vitamin K rebuilds osteoporotic bone and removes arterial calcium in animal studies. He links this to CO2 handling, and says baking soda helps bone. It then lists PMID-cited excerpts: human studies and a systematic review on vitamin K2/MK-4 and fractures or bone loss, and rat studies on arterial calcification.
The author shares a review excerpt saying many animal species, from birds and frogs to elephants, follow conversational turn-taking rules, citing PMID 29875303. The embedded lowmegatron post quotes Ray Peat on Chomsky, language and animal consciousness. There is no human health content.
The post quotes an article on hypothyroidism presenting with psychiatric symptoms (cognitive dysfunction, affective disorders, psychosis), and a historical case report of a woman whose hallucinations and appearance improved within weeks of thyroid treatment. The embedded post is from KruseYouri: 'Thyroid therapy for people in mental clinics'.
The post quotes one line, 'Vitamin K2 treatment effectively prevents the occurrence of new fractures...', and embeds lowmegatron's earlier post. That post has Ray Peat's remarks on vitamin K, bone, arterial calcium and CO2, plus PMID-cited vitamin K excerpts.
The author says higher coffee intake is associated with slower cognitive decline and possible protection against Alzheimer's. They quote a paper (PMID 34867277) reporting up to 8% less executive-function decline over 18 months when going from 1 to 2 cups/day, and a lower risk of progressing to MCI/Alzheimer's over 126 months. The quoted post from lowmegatron reports about 30% lower type 2 diabetes (T2D) risk at 5 cups/day.
The author says CFS patients tend to have lower T3 and higher reverse T3 with normal TSH. They interpret this as a thyroid hormone conversion problem and low thyroid hormone activity, and say TSH is useless for identifying deficiency in sick people. An unnamed quoted passage says tissue T3 may be severely reduced. The embedded post from lowmegatron adds a personal T3 recovery anecdote and a study excerpt calling for confirmation.
The post announces a thread titled 'Tips to Boost Thyroid Hormones' with a link and attached media. No substantive content is included in the retrieved text.
lowmegatron claims that cortisol, glucagon and adrenaline inhibit T4-to-T3 conversion, lowering T3 and raising reverse T3 in a vicious cycle. He lists common, easily corrected causes of high cortisol and adrenaline (poor sleep, too little carbohydrate, sodium, potassium, magnesium or calcium, fasting, chronic caloric restriction, noise, shallow breathing, black coffee on an empty stomach, constant stimulation). He suggests acerola vitamin C, L-theanine and glycine may help.
lowmegatron says iodine is essential for thyroid hormone synthesis but that deficiency and high doses can both cause thyroid problems, including hypothyroidism, hyperthyroidism or autoimmunity in susceptible people. He cites the RDA of 150 mcg, says intakes above 300 mcg daily may pose risks, and names seafood and dairy as good sources. The quoted parent context (a Ray Peat quote and PMID 25050783 on excess iodine and thyroiditis) is context, not part of this post's own text.
lowmegatron claims the thyroid adjusts to energy availability, so undereating or chronic overexertion reduces thyroid hormone production, conversion or tissue sensitivity and lowers metabolic rate. He warns against combining fasting with intense exercise. He recommends muscle-focused exercise and suggests mild, careful caloric restriction balanced with periods of adequate intake.
lowmegatron claims goitrogens, mainly cruciferous vegetables and soy products, can interfere with thyroid hormone levels even before a goiter appears. He says cooking reduces them, so raw or lightly cooked foods are riskier, and that iodine insufficiency increases their effect.
lowmegatron claims unsaturated fats, especially PUFA from seed oils and from non-ruminant animals fed high-PUFA diets, disrupt thyroid hormone production, transport and binding, and that stress releases them as free fatty acids. He recommends mostly saturated fats (coconut oil, cocoa butter, butter/ghee, cream and cheese, tallow) and lists oils to avoid, including fish oil.
lowmegatron claims phthalates and BPA/S/F in plastics impair thyroid gland function and peripheral thyroid hormone conversion, and that BPA blocks thyroid hormone at the receptor. He lists common sources (fragrance in cosmetics, plastic containers and bottles, can linings, dust, thermal receipts). The quoted context, a separate post citing PMID 31757552, reports a rat study in which ginger protected against BPA-induced thyroid damage.
lowmegatron promotes his Hypothyroid Masterclass group as a clear, no-nonsense guide. He says it covers the thyroid system, disorders caused by low T3, hormone metabolism, medications, and how diet and stress affect test numbers, with 30 videos and a support group.
The author quotes a paper (PMID 26295257, marked with a rodent emoji) saying high-dose MK-7 inhibits cardiovascular calcification. The embedded post from lowmegatron quotes Ray Peat and several papers on high-dose vitamin K for bone and arterial calcification, plus CO2 and baking soda for bone.
The post quotes Ray Peat saying synthetic citric and ascorbic acids differ from natural forms and may carry industrial or microbial contaminants. He says citric acid increases urinary calcium loss, that calcium carbonate is safer and supports bone formation, and that chronic high citric acid intake is suspected to be carcinogenic. The author adds a note that the mold used for manufactured citric acid differs from S. chartarum, and that both can cause inflammation and immune issues if consumed.
Author links coffee, cortisol and depression: 11β-HSD1 raises local cortisol, is reported as upregulated in the DLPFC in depressed people, and is said to be lowered by coffee. Author also says coffee intake is associated with lower depression risk and lower suicide risk. The quoted post separately links coffee's anti-diabetic effects to 11β-HSD1 inhibition.
Author says vitamin K2 (from cheese) and a higher calcium-to-phosphate ratio help regulate calcium and keep it out of soft tissue. The quoted account claims whole-fat dairy in childhood was linked to 24% lower odds of adult artery calcification.
Post shares a quotation attributed to Ray Peat saying zeolite in stomach acid can itself be a source of toxins.
Short, context-dependent remark that 'he' could be happily married with six kids or dead from vitamin A deficiency by now; the referent is in unretrieved media.
lowmegatron points readers to his course on hypothyroidism and lists links to his threads on the thyroid system, thyroid hormone tests, 'Light is the most effective treatment for Hashimoto's' and 'Stress causes hidden hypothyroidism'. The titles are his claims; the linked pages are not supplied.
Post contains only a period and a media link; no text content is retrievable.
Author states coffee drinkers have a lower risk of gout, reporting 40% lower at 4 cups/day and 59% lower at 6 cups/day, and quotes a prospective cohort excerpt of men.
The author quotes Ray Peat saying hair binds copper from air and water, so hair mineral tests are invalid, and that toenails are better. Peat recommends weekly shellfish to keep copper adequate. The quoted context is a Peat remark that zeolite in stomach acid can itself be a source of toxins.
Author says shingles can cause nerve pain/neuritis, possibly via myelin sheath destruction, and that this can often be improved with vitamin B1. Author adds that low available T3 also causes demyelination, then quotes an old passage describing Stevenson's B1 treatment of neuritis and sciatica cases.
Author explains natural desiccated thyroid (NDT): it contains T4 and T3 (about 4-5 times more T4), is dosed in grains, and is sold under many brands. Author says it works well for many people, and that synthetic combinations usually work as well and are more reliable and often cheaper.

The embedded lowmegatron post adds a Ray Peat quote and several cited abstracts on vitamin K, bone and arterial calcification.
Author claims fructose limits muscle wasting and thyroid hormone decline during fasting or dieting. They cite a 10-day fast in obese people where fructose infusion reduced nitrogen excretion and blunted hormone and metabolic changes. The embedded lowmegatron post lists factors said to inhibit thyroid hormone conversion.
Post shares a Ray Peat quote linking GERD to disturbed gut muscle action and factors including high estrogen, serotonin, prostaglandins, low thyroid, inflammation and small-intestine bacterial overgrowth, suggesting a daily raw carrot. It adds two quoted abstracts (PMID 38803365, PMID 7119407) linking hypothyroidism to esophageal motility problems and reflux.
Post shares a Ray Peat quote on improving thyroid hormone conversion: selenium deficiency correction works quickly, intestinal flora problems must be addressed, and other nutritional factors such as daily raw carrot, weekly seafood and liver, sunlight, vitamin D and calcium-to-phosphate balance are often helpful. The embedded post is a lowmegatron thread on selenium and thyroid, whose content is not included.
Author criticizes the omission of the thyroid hormone T3, calling it 'insanity'. The post quotes a Medscape post saying overtreating mild or subclinical hypothyroidism in older adults may be more harmful than helpful.
Author shares a Ray Peat quote and cited excerpts (PMIDs) suggesting caffeine or coffee may protect against skin cancer and melanoma. The quoted lowmegatron post separately claims decaf coffee improved gut barrier markers in a rodent high-fat diet model.
Author lists gastrointestinal manifestations of hypothyroidism and quotes a paper (PMID 38803365) saying gastric dysmotility often improves with thyroid hormone replacement and that thyroid function should be evaluated in patients with GI complaints. The quoted post adds a Ray Peat GERD quote and a case report.
Author shares a Ray Peat quote saying hypothyroid people incompletely oxidize glucose, causing blood glucose fluctuations and increased appetite, and that appropriate thyroid hormone and sometimes pantothenic acid help. The quoted lowmegatron post claims reduced brain glucose oxidation in depression that T3 availability may reverse.
Author states that pregnenolone lowers stress and reduces alcohol cravings at 300-500 mg/day and quotes a trial abstract (PMID 36445398) reporting reduced stress- and cue-induced craving in individuals with alcohol use disorder. The quoted post shares a Ray Peat quote linking alcohol cravings to hypothyroidism and high serotonin.
The author asks whether vitamin A deficiency severe enough to cause dandruff and acne could also cause anxiety. They cite a Ray Peat quote that it could, because vitamin A is needed to make pregnenolone and progesterone. A bracketed note, apparently the author's own, says retinoic acid upregulates StAR, and that without enough StAR cholesterol delivery and pregnenolone synthesis fall.
The author states that fructose is made in the human brain under normal conditions. They quote a passage saying MRS studies show cerebrospinal fluid fructose about 20-fold higher than blood, and that its precise roles remain under investigation. The embedded post by lowmegatron claims fructose infusion during a 10-day fast in obese people blunted fasting-induced hormonal and metabolic changes and spared protein.
The author quotes Ray Peat saying that with insufficient cholesterol the high postpartum progesterone is unlikely to be maintained, and that pro-inflammatory effects of serotonin and estrogen then predominate, causing depression, joint pain, anxiety and brain edema. The author adds that postpartum depression drugs (brexanolone, zuranolone) relate to allopregnanolone, a progesterone metabolite. They also lay out the cholesterol-to-allopregnanolone pathway and note its dependence on T3 and vitamin A. They cite a postpartum cholesterol and mood study (PMID 8845727). The embedded lowmegatron post quotes a thyroid study on T3, TSH and depression (PMID 9971866).
The author asserts that without thyroid hormone T3 everything fails. No explanation is given.
A brief morning greeting with coffee, milk and honey emojis and the line 'Protect the caffeine.' It quotes an earlier lowmegatron post listing foods and habits (coffee, raw milk, maple syrup 'to protect the caffeine', early walk, eggs and sourdough, sunlight then red light, and so on), followed by an unrelated description of Erling Haaland.
Post quotes Ray Peat saying acetazolamide, caffeine, thyroid and progesterone stimulate respiration and help sleep apnea, that thyroid is the main regulator of respiration, and that obstructive apnea is probably the same condition as other apnea. It pairs this with a quoted conclusion from a systematic review and meta-analysis of acetazolamide for obstructive and central sleep apnea.
The post states that TSH can stimulate thyroid cancer. It cites Ray Peat on keeping TSH near zero to reduce recurrences and quotes a report (PMID 11701668) of two papillary thyroid carcinoma patients whose tumors grew after rhTSH injections. An embedded quoted post from lowmegatron links subclinical hypothyroidism to raised inflammatory markers and lipids.
The post quotes Ray Peat saying T3 is the best thing for controlling serotonin's effects and criticizing serotonin as a 'happy hormone' consensus view. The embedded lowmegatron post argues that low cholesterol postpartum may contribute to depression, and that allopregnanolone, a progesterone metabolite, is used for postpartum depression and can be raised by progesterone or pregnenolone.
The post states that in-utero acetaminophen exposure feminizes males. It supports this with quoted text from a mouse study (PMID 28559473) reporting fewer neurons in the sexually dimorphic nucleus of the preoptic area and altered sexual and territorial behavior in exposed male offspring. An embedded lowmegatron post claims finasteride in rats affected sexual behavior.
The post claims pregnenolone helps with alcohol cravings partly by inhibiting TLR4. It supports this with a Haidut quote about naltrexone, a university statement on a mouse study of (+)-naltrexone and drinking, and excerpts on neurosteroids suppressing TLR signaling. The embedded lowmegatron post quotes a placebo-controlled human study of pregnenolone at 300 mg/day and 500 mg/day in alcohol use disorder.
The post quotes Ray Peat as preferring Coca-Cola to Pepsi, because from mineral analyses he had seen Coke would have more botanical extracts. It also shows a quoted post from lowmegatron citing a mouse study, in which Coca-Cola or Pepsi was associated with higher testis mass, serum testosterone and androgen receptor mRNA expression.
The sharing account added no text of its own, only a link and a quoted post. The quoted primal_diet post advises against breastfeeding and says raw cow's milk should be given instead, or a mix of both as a compromise.
The post quotes a passage from a paper titled 'Regulation of Bone Mass by Serotonin: Molecular Biology and Therapeutic Implications'. The passage says that inhibiting gut serotonin synthesis is a tantalizing hypothesis as an anabolic osteoporosis treatment, and that related issues now belong more to the industrial than the academic world.
The author says that men on a long-term low-PUFA diet should master de-escalation. This is a reply-style remark to a quoted post, which jokes that very large testicles raise the risk of contusions during a fight. The exchange is largely humorous or social, and no mechanism or evidence is given.
The author says drinking 2-4 cups of coffee per day is associated with lower TSH, and that high TSH is itself inflammatory and linked to several conditions. The author also says more than 2 cups per day is associated with a 40% lower risk of subclinical hypothyroidism, citing PMID 37351106. The quoted lowmegatron post reports a rodent study in which decaf coffee increased tight junction protein expression and reduced TLR4 expression in rats fed a high-fat diet.
The author states that elevating the head of the bed reduces sleep apnea, quoting a study abstract reporting lower AHI and a lower percentage of apneas with a 30° head-and-trunk elevation (HOBE) compared with a flat supine position.
The author claims serotonin is a cause of insulin resistance. The post quotes Ray Peat on intestinal inflammation, endotoxin, nitric oxide and serotonin driving insulin resistance, and a paper excerpt on gut-derived serotonin and glucose tolerance in mice. An embedded post quotes Peat saying T3 best controls serotonin's effects.
The author claims low thyroid activity raises serotonin and histamine, causing itching. The post quotes Broda Barnes on winter itch in hypothyroid patients responding to thyroid therapy. An embedded lowmegatron post links seasonal thyroid sluggishness to reduced near-infrared (NIRA) light and Hashimoto's.
The author claims a little sugar lowers stress hormones, citing a rat study in which sucrose or saccharin drinking dampened HPA-axis stress responses. An embedded post says fasting and high cortisol lower thyroid hormone and suppress TSH, so thyroid tests can mislead under stress.
The author states that insufficient sleep increases pain sensitivity and caffeine reduces it, quoting excerpts on sleep-deprived animals and habitual caffeine consumers, with a note not to dose caffeine so it interferes with sleep. An embedded post reports 3 mg/kg caffeine reduced perceived muscle soreness after cycling.
The author states that mice try to resuscitate unconscious mice and that this brings the others back to consciousness faster, with a link. The embedded post quotes Ray Peat on Chomsky, language and animal consciousness.
The author advises following the money when seeing anti-coffee or anti-aspirin stories, with a link. The embedded post says aspirin may slow fatty liver disease, citing an observational study of daily aspirin users and listing proposed mechanisms.
The post quotes Ray Peat linking reduced deep slow-wave sleep in hypothyroidism, old age, schizophrenia and depression to serotonin and torpor-like brain-stress states. The embedded post quotes Peat plus a 1967 study of EEG sleep in hypothyroid patients, with slow-wave sleep increasing after desiccated thyroid.
The author states magnesium sometimes reverses depression and that magnesium deficiency elevates brain serotonin. The post quotes case histories reporting rapid recovery from major depression with magnesium glycinate and taurinate taken with meals and at bedtime.
The author states depression is a low-brain-energy state that can be caused by low thyroid hormone and introduces a thread on the thyroid system's role in depression.
lowmegatron claims glucose oxidation is reduced in brain regions associated with depression, meaning less efficient fuel use, lower CO2 and more lactate. He says lithium, when effective, lowers lactate in these regions in bipolar depression. The root post frames depression as low brain energy.
lowmegatron says T3 is needed for optimal glucose oxidation and that brain glucose metabolism is reduced in hypothyroidism. He quotes text describing reduced brain glucose metabolism in hypothyroid patients that is restored after thyroid hormone replacement, and reduced phosphocreatine to inorganic phosphate ratios.
lowmegatron says T3 supplementation has antidepressant effects that track with improved brain energy in people with antidepressant-resistant depression. He quotes a source saying T3 augmentation of SSRIs correlates with changes in brain bioenergetic metabolism.
lowmegatron says depression is a long-known symptom of hypothyroidism that is now overlooked because of serotonin and psychological theories and misunderstanding of blood tests. He claims blood tests do not reflect tissue status, especially in the brain, and quotes sources on D2 enzyme inhibition and psychiatric presentations. He also quotes an old case report of a woman with psychosis and myxedema whose symptoms resolved after thyroid treatment.
lowmegatron argues that thyroid testing focuses on TSH and T4 and that many people have poor T4-to-T3 conversion. He claims many depressed people have low T3 and that rising TSH is ignored when T4 is normal. He quotes a study reporting lower T3 and higher TSH across depression severity grades and suggesting subclinical hypothyroidism.
lowmegatron claims TSH is influenced by stress and diet independent of T3 status, and that T4 is not a great way to optimise T3. He cites a study identifying a TSH of 2.5 mU/L as the optimal cutoff for predicting depression symptoms in T4-treated hypothyroid patients, versus the usual upper cutoff of about 4.5.
lowmegatron claims T3 can help treatment-resistant depression even when thyroid blood tests are normal. He quotes a case report of a perimenopausal woman with failed antidepressant trials who was given liothyronine and reported improved mood within 4 weeks, with thyroid labs staying normal.
lowmegatron says high-dose T4 has been used in bipolar depression. He argues that T4-only treatment is not ideal for optimizing T3 because of conversion issues, but that the results show levothyroxine can still improve outcomes. He quotes a study concluding that supraphysiologic thyroid hormone improves depressive symptoms in bipolar disorder.
lowmegatron argues that null trials of thyroid hormone in depression are uninformative because they use fixed or TSH-based dosing and do not address suboptimal T3. He compares this to giving T1D patients the same insulin dose. He cites a report dosing T4+T3 to an upper-range free T3 and a TT3/RT3 ratio of 10:1 or better, with an average 46% improvement in depression, and quotes a clinician's case of a thyroidectomy patient whose fatigue and depression resolved.
lowmegatron claims that adding T3 to T4, even without individualized dosing, can improve mood and cognition in hypothyroid patients. He quotes a study in which several cognitive and mood scores were better after T4 plus T3 than after T4 alone.
lowmegatron summarizes his thread: he claims low T3 activity is implicated in depression, that T3 is needed for glucose oxidation, and that basic TSH/T4 testing and treatment are inadequate for assessing T3 status. He recommends patient-tailored approaches using T3, reverse T3, symptoms and basal temperature. He adds caveats that low T3 is not the only cause of depression and that thyroid hormones, especially T3, should not be taken carelessly. A numbered reference list is included.
Author states that mice lacking TPH2 (the enzyme controlling brain serotonin synthesis) are resistant to depressive behaviour. A quoted passage says this questions serotonin's role in depression and suggests such mice as a model for non-serotonergic antidepressant targets. The embedded post, by lowmegatron, links serotonin to blood-brain barrier leakiness in depression.
Author says there is substantial criticism of the serotonin theory of depression, contrary to popular press and alt-health media. The post collects quotes from named clinicians and researchers saying serotonin deficiency has not been shown to cause depression. The embedded post shares a Ray Peat quote that serotonin is high in learned helplessness.
Author recommends a paper and quotes press coverage of a review arguing that more serotonin, not less, is released in depressive episodes. The quoted coverage says SSRIs may interfere with the brain's recovery mechanisms. The embedded post says any SSRI benefit may be a reaction against serotonin that raises neurosteroids.
Author asserts depression is largely a brain energy problem and quotes text saying most studies found no reduced serotonin activity in depression and that tryptophan depletion does not reliably lower mood. The embedded post says high serotonin is a likelier cause of depression and anxiety, and that SSRI benefits may work through allopregnanolone.
Author states that progesterone and allopregnanolone reduce learned helplessness, an animal model analogous to depression, and that learned helplessness is characterized by increased brain serotonin.
Author says serotonin causes helplessness, reversible by serotonin blockers such as methysergide, and that T3 acts against learned helplessness, probably partly by opposing serotonin. Brain serotonin is said to rise in hypothyroidism in animal experiments. The embedded post says recovery from the Voodoo Death Phenomenon can occur by the same mechanism that caused it.
Brief social greeting to sports fans saying 'Protect the caffeine' with honey emojis. The embedded DoctorTro post says the world's best soccer player eats meat and raw milk and gets sunlight, all 'against medical advice'.
Author lists conditions said to be caused by bacterial endotoxin entering the bloodstream in leaky gut, then lists nutrients, drugs, foods and lifestyle factors said to reduce endotoxin or its inflammatory effects. The embedded post claims pregnenolone curbs alcohol cravings partly through TLR4 inhibition.
Author shares a Facebook commenter's anecdote (posted with permission) about depression and feelings of helplessness after a thyroid crash with low T3. The commenter says starting Cynoplus with extra T3 lifted the depression quickly. The commenter also claims many women have inadequate T3. The embedded post says depression is a low brain energy state that can be caused by low thyroid hormone.
Author says cocaine amplifies endotoxin effects while magnesium protects. Slightly elevated endotoxin is said to cause depression, T2 diabetes, low testosterone, infertility and cardiovascular disease, while very high levels can be lethal. A quoted rat study reports worse survival with magnesium deficiency. The embedded post links endotoxin to diabetes and fatty liver, quoting Ray Peat and human studies.
The post author says endotoxin raises cortisol and that chronically elevated cortisol can cause low testosterone, weight gain, insulin resistance, type 2 diabetes and depression. They quote a human endotoxin-administration study reporting dose-related rises in inflammatory markers, cortisol and norepinephrine. The embedded quoted post from lowmegatron says blocking the glucocorticoid receptor lowers glucose and insulin in obese diabetic mice. It also lists many things it says help lower cortisol.
The post author explains non-exercise activity thermogenesis (NEAT) and says metabolic rate and thyroid hormone T3 strongly influence it. They say higher NEAT helps prevent fat gain, and that hyperthyroid rats and humans move more while hypothyroid rats and women move less. The embedded quoted post from lowmegatron argues that low T3 activity is implicated in depression and that standard TSH/T4 testing is inadequate. It adds cautions about thyroid hormone use.
The post author says vitamin K protects against the testosterone reduction caused by bacterial endotoxin. They quote a rat study in which rats on a vitamin K-free diet had lower plasma testosterone after endotoxin than controls. The embedded quoted post from lowmegatron says endotoxin causes low testosterone and infertility in men.
The post author highlights a study of a rural West African population on a diet of about 84% carbohydrate, mostly cassava starch. None of the 1381 subjects had diabetes. The study is quoted as suggesting that high carbohydrate with low protein does not cause diabetes. The embedded quoted post from lowmegatron says orange juice improved HOMA-IR insulin resistance and gut bacteria in young women.
The post is a quotation from Ray Peat. He says gut-derived endotoxin impairs mitochondrial energy production and can cause hypoglycemia. He recommends a balanced natural diet rich in fruit, such as orange juice, whose potassium he says helps handle sugar without disturbing insulin. He says this supports thyroid hormone activation and can restore steady blood sugar within a day or two.
Author posts a single short statement, "Don't die an Ancestral Death." No health content is stated explicitly.
Author describes a case report of a woman whose manic symptoms after gastrectomy for obesity reportedly resolved within two weeks on 1 g/day activated charcoal, with a quoted mechanism proposing a brain–gut axis. The embedded lowmegatron post claims bacterial endotoxin from leaky gut causes many conditions and lists interventions said to help with endotoxin.
Author shares a Ray Peat quotation linking Candida growth to hypothyroidism, estrogen excess, stress and poor glucose oxidation. Peat says inflammation and improper glucose oxidation are typical of cancer metabolism, and Candida intensifies the inflammation. He mentions Simoncini.
Author shares a Ray Peat quotation describing his own experience with desiccated thyroid, which he says brought pleasure and a wish to smile. He also describes suicidal women using thyroid or progesterone, who he says changed from weeping to smiling within hours. The embedded lowmegatron post claims depression is a low-brain-energy state that can be caused by low thyroid hormone.
The author shares Ray Peat's statement that thyroid hormone raises energy, the CO2/lactate ratio, brain temperature and the progesterone-to-estrogen ratio. A second quotation, not attributed in the retrieved text, calls lactate necessary for carcinogenesis. The author then argues CO2 itself has anticancer effects, citing Japanese rodent experiments in which transcutaneous CO2 treated human cancer xenografts. The quoted post from doctorinigo presents a lactate 'Lactagenesis' hypothesis.
Ray Peat, quoted by the author, recalls reports of a man who became intoxicated after eating sugar because yeast grew in his gut. He attributes such problems to weak digestion from low thyroid, suggests thyroid supplementation would probably resolve the yeast and bacteria problem, and describes experiments attributed to René Dubos on yeast becoming invasive when starved of sugar.
The author states that Nauheim carbonated baths have traditionally been used for cardiovascular disease and lead to CO2 uptake. The post quotes Ray Peat on the history of carbonated baths and the Japanese finding that CO2 enters the body against the expected gradient. It also quotes a historical Nauheim text crediting the baths' effect on heart patients and a PMID-labelled statement that some evidence supports CO2 baths in cardiovascular rehabilitation. The quoted post is a timestamped Ray Peat/Bud Weiss audio on CO2.
The author shares an anonymous Facebook comment, posted with permission, describing a couple's reported results from T3 thyroid hormone. The commenter reports resolution of calcification/sclerosis, myxedema, psoriasis, PMDD and high cholesterol, among other changes. The quoted post from lowmegatron discusses high-dose T4 in bipolar depression.
Ray Peat, quoted by the author, suggests pregnenolone avoids the risk of DHEA converting to estrogen when thyroid function is low. He says a small amount of Armour thyroid could quickly lower cholesterol and probably help testosterone, and recommends shellfish, low-fat fish, eggs, liver, cooked potatoes with butter or cream, fruit and cooked greens for nutrients.
The post says thyroid hormone (T4) replacement roughly doubled free and total testosterone and halved prolactin in hypothyroid men. It quotes the study's conclusion that primary hypothyroidism can cause reversible hypogonadotrophic hypogonadism. The author adds that the men were still far from optimal and that more progress was possible. The embedded quoted post (lowmegatron) gives a Ray Peat quote on low testosterone and high cortisol.
The post says hypothyroidism decreases testosterone and testicular weight. It quotes a rat study of experimentally induced hypothyroidism, which reported lower testosterone and body and testes weight with no change in LH and FSH. The embedded quoted post is the earlier human T4 replacement study post by lowmegatron.
The post says subclinical hypothyroidism causes low testosterone and erectile dysfunction. It reports that men with TSH 4.5-10 and normal T4 had lower testosterone, higher prolactin and weaker sperm, and that two thirds reported ED. The post claims TSH above 2.0 should be a red flag but is usually ignored. The embedded quoted post is the earlier rat hypothyroidism post.
The post shares a Ray Peat quote saying topical testosterone is safe if diet and thyroid function are good, but that pregnenolone and then DHEA should be tried first to normalize testosterone production. The embedded quoted post is the earlier subclinical hypothyroidism post by lowmegatron.
The post says hypothyroid people move less, quoting a finding that physical activity duration and steps were significantly lower in a subclinical hypothyroid group. The embedded quoted post (lowmegatron) discusses NEAT, claiming T3 and metabolic rate strongly influence it and citing rat and human findings with PMIDs.
The author comments that a person was 'one-shotted by excessive iodine'. The quoted account (RealitysaGame) says they went overboard with an unnamed item ('this'), ended up in thyroid crisis, and needed a couple of months to get it under control. The quoted account advises not to overdo it, without saying not to try it.
The author shares a Ray Peat quote that coffee provides very significant quantities of magnesium. The embedded post by 5HTskeptic adds that Peat brewed very strong pour-over coffee, making a concentrated brew like espresso and a rich magnesium source, and compares standard coffee with espresso.
The author compiles excerpts from three cited papers on aspirin in COPD. Two are observational and link aspirin use to lower mortality in critically ill patients and to fewer exacerbations, less dyspnea and better quality of life. The third is a 4-week placebo-controlled trial of inhaled aspirin in 59 people with moderate COPD, reporting lower inflammatory markers and improved lung function at 250 mg. The embedded Medscape post is general COPD content.
The author argues that rising TSH tracks with rising bodyweight because high TSH reflects low thyroid hormone. They say thyroid hormone drives resting metabolic rate and NEAT, so low levels mean lower metabolism and more fat storage. They quote a community-based study (PMID 18362250) reporting a linear association between TSH and weight. The embedded lowmegatron post links NEAT to metabolic rate and T3.
The author claims that reducing excess iron lowers cancer risk, citing reductions in cancer deaths, incidence and all-cause mortality (PMID 18612130). They say iron promotes lipid peroxidation of PUFAs. They quote Ray Peat's advice on vitamin E, coffee, unsaturated fats, vitamin C and copper in relation to iron. The embedded lowmegatron post claims coffee protects DNA by lowering lipid peroxidation, citing a randomized study.
The author says SIBO and IBS can be caused by hypothyroidism and that levothyroxine absorption is reduced by all three conditions. They cite a study reporting that switching from tablet to liquid levothyroxine improved GI symptoms and TSH in patients with SIBO. They argue that dosing to a normal TSH is inadequate and that correcting T3 would improve outcomes more. The embedded lowmegatron post shares an anecdote of SIBO resolving after T3 treatment and adds hypothyroidism-SIBO claims.
The author claims that 81 mg aspirin started preconception raised live-birth rates in women with high C-reactive protein. They report a 34% relative (15% absolute) increase versus placebo, from a secondary analysis of a randomized trial. The embedded lowmegatron post says aspirin lowers COX-2, interferes with seed oil inflammatory effects and reduces pancreatic damage in experimental pancreatitis.
The author claims vitamin K2 is critical for cardiovascular health in SIBO. They say SIBO is linked to arterial stiffening and inactive MGP, and that MGP depends largely on vitamin K2 to inhibit vascular calcification. They quote a study (PMID 28275304) on reduced MGP activation and suggesting SIBO screening, decontamination and K2 supplementation. The embedded lowmegatron post quotes a claim about pharmacological-dose K2 and calcified arteriosclerosis.
The post text is only a link. It quotes Bryan Johnson's post showing his morning meal, with longevity scores from four AI models. The sharer adds no commentary.
The author explains how menstrual-cycle timing affects basal temperature testing for thyroid status. They say hormonal birth control and HRT make the Barnes basal-temperature test unreliable. They quote Broda Barnes on using basal temperature to guide thyroid treatment and on the test's limits.
The author advertises the Hypothyroid Masterclass, a video course with a support community, aimed at people with normal thyroid labs who still feel hypothyroid. Most of the post is a list of module topics.
A brief title-like post naming SIBO and thyroid hormones, with no explanation or claim in the retrieved text.
The author says two extra cups of coffee per day is associated with about 38–48% lower risk of cirrhosis or death from it. They also say coffee can prevent or reverse alcohol-induced liver damage via several mechanisms. The quoted lowmegatron post links coffee to lower TSH and lower subclinical hypothyroidism risk.
Post quotes Ray Peat saying an inefficient liver with low overnight glycogen storage commonly causes headaches and shakiness, and suggesting light exposure, weekly liver and oysters, low stress and bedtime cyproheptadine. It adds a quoted study conclusion that cyproheptadine may be effective for migraine prevention in patients for whom conventional drugs failed or caused side effects.
The author argues that hormones, especially estrogens, shape Candida growth and virulence, using a series of study excerpts. The excerpts say estrogen promotes Candida albicans virulence and immune evasion while progesterone reduces virulence factors. The author notes this is mostly relevant to vaginal candidiasis, not white tongue or GI overgrowth. The embedded post quotes Ray Peat on sugar, yeast, low thyroid and digestion.
Post quotes Ray Peat saying quick intestinal transit goes with abundant digestive secretions that keep the small intestine free of bacteria, and that good thyroid function and antiseptic foods such as cooked mushrooms, bamboo shoots and raw carrots help.
The author states that gut serotonin causes obesity and type 2 diabetes, citing a quote from Professor Damien Keating that gut-derived serotonin causes diabetes and obesity and that their findings implicate serotonin as a driver of worsening obesity in humans. The embedded post quotes Ray Peat linking serotonin and torpor-like states to reduced deep sleep and brain stress states.
The author asks 'Phthlate gut?' and lists health harms attributed to phthalates, including reduced testosterone, reproductive, neurodevelopmental, metabolic, respiratory and thyroid effects. The post quotes a human correlation finding on abdominal obesity and insulin resistance and a mouse study reporting weight gain and metabolic changes. The embedded post by lowmegatron claims phthalates are detoxed by glucuronidation and lists factors said to help or hinder it.
The author says blue light raises blood sugar and insulin, while 670 nm red light lowers blood sugar and increases ATP. They cite two studies, one on blue-enriched light and one on 670 nm red light. They suggest minimizing blue light and increasing red light exposure.
The author claims much mental illness begins in the gut because bacterial endotoxin poisons mitochondria and leaky gut lets more endotoxin into circulation. They quote a systematic review and meta-analysis on gut dysbiosis markers in severe mental illness and chronic fatigue. They then list nutrients, foods and other factors they say reduce endotoxin or endotoxin-driven inflammation.
lowmegatron clarifies an earlier post: in the line "It also damages the brain, heart, and other internal tissues," "it" refers to lipofuscin, not creatine. The parent post is not supplied.
The author says coffee reduces fatty acid synthase, an enzyme that creates fat, which they say feeds cancer. They quote excerpts from two named papers on coffee components and lipogenesis and on FASN in cancer. The embedded quoted post from lowmegatron claims coffee intake is associated with lower cirrhosis risk and lists proposed liver-protective mechanisms.
The author lists nutrients, foods and other factors they say can help with high histamine, including correcting hypothyroidism and estrogen dominance. The embedded post from lowmegatron introduces a thread on histamine hacks and lists conditions in which histamine is implicated.
The posting author argues that seed oil (linoleic acid) intake probably plays a large role in Hashimoto's susceptibility, citing a rodent study where a high-linoleic-acid diet was followed by thyroid autoimmunity and hypothyroidism. The author links this to lipid peroxidation and says seed oils are tied to other autoimmune diseases partly via pro-estrogenic properties. The embedded quoted post (lowmegatron) cites register data on suicide and unknown-cause death in Hashimoto's and gives that account's opinion that inadequate treatment, T3 and temperature are involved.
The post pairs a Ray Peat quote saying slight hypothyroidism commonly causes chronic urinary infections, because thyroid hormone and progesterone support IgA and reduce histamine resistance. It then quotes a case report of a woman with recurrent urinary tract infections and slightly raised TSH who had no recurrence for 10 months after levothyroxine 25 mcg.
The post claims that lowering iron, via phlebotomy, reduces insulin resistance in people with NAFLD, quoting a paper. The author adds a mechanism: iron plus seed oils creates a pro-oxidative environment that forms lipid peroxides such as 4-HNE and damages mitochondria and insulin signaling. The embedded quoted post (lowmegatron) cites iron reduction and lower cancer risk and includes a Ray Peat quote on iron, vitamin E, coffee, vitamin C and copper.
The post quotes a Ray Peat Q&A saying age spots may be caused by high estrogen or polyunsaturated fats, and suggests reducing PUFAs, using vitamin E orally or topically, and topical niacinamide for sun-induced spots. The author adds that PUFAs are found in seed oils, fish oils, pork and poultry fat, and quotes a case report on vitamin E deficiency and lipofuscin.
The post quotes Ray Peat saying stress hormones lower thyroid hormone conversion, so TSH alone cannot diagnose thyroid problems. The embedded quoted post (lowmegatron) says stress causes hidden hypothyroidism that often goes undetected in blood tests.
The post author says healthy low-BMI (underweight) people move less but have higher-than-expected resting energy expenditure linked to higher thyroid hormone levels. The author quotes a study of Chinese adults and a researcher (Sumei Hu). The embedded quoted post (lowmegatron) separately discusses NEAT, thyroid hormone T3 and physical activity.
The author announces a live course on low thyroid, with video lessons and a support community. It is described as covering hormones, tests, diet, supplements and lifestyle, with a focus on proper testing, hidden hypothyroidism and causes of thyroid hormone suppression.
The author says breakfast lowers stress and that skipping it disrupts metabolism. The author quotes a study on skipping breakfast, higher post-meal glucose, lower iGLP-1 and impaired insulin response in type 2 diabetes. The embedded quoted post (lowmegatron) claims coffee reduces fatty acid synthase and lipogenic enzymes, linking FASN to cancer.
The author cites a study excerpt claiming high prolactin reduces the conversion of testosterone to DHT by 5-alpha-reductase in men. He adds that hypothyroidism doubles prolactin in men. The quoted context says thyroid hormone doubled testosterone and halved prolactin in hypothyroid men treated with T4.
The author says people with TSH in the upper half of the normal range are 70% more likely to have metabolic syndrome. The author also says this is a red flag for thyroid hormone metabolism and that TSH itself is inflammatory, quoting a study on high-normal TSH.
The post asks whether supplements can safely raise serum androgens in men if diet is good, and answers with a Ray Peat quote. Peat says pregnenolone has favorable effects. He also says thyroid or aspirin can improve the androgen-to-cortisol/estrogen ratio, and that low-dose DHEA can help if thyroid function is good. An embedded post by lowmegatron links subclinical hypothyroidism to low testosterone and ED in men.
The author states that creatine powers cancer-killing T cells. The post quotes text saying creatine supplementation in mice significantly suppressed tumor growth across multiple mouse tumor models, acting as a 'molecular battery' that conserves bioenergy for T cell activity.
The author argues that antibiotics (minocycline) are effective in rheumatoid arthritis, via reduced bacterial endotoxin and TLR4-driven inflammation. The author also says tobacco endotoxin may explain higher RA rates in smokers. Five source titles are listed. An embedded lowmegatron post quotes Ray Peat on endotoxin, mitochondrial function, hypoglycemia, and fruit and orange juice as a way out of the cycle.
The author says decreased thyroid hormone conversion is associated with worse physical performance and lower grip strength in older men. The explanation is that T4 converted to rT3 instead of T3 lowers energy production. A quoted study excerpt reports rT3 rising with age and disease, and low T3 syndrome linked to lower physical performance. An embedded lowmegatron post says creatine increases grip strength by raising energy availability.
The author reports thyroid hormone downregulation in pre-eclampsia, quoting a cross-sectional study. Women with pre-eclampsia had higher TSH, lower free T3 and free T4, and more subclinical and overt hypothyroidism than normotensive women, with severity tracking thyroid dysfunction. An embedded lowmegatron post says improving thyroid status with levothyroxine reversed high blood pressure in 50% of very hypothyroid patients.
The author says standard thyroid labs can miss a slow metabolism, that levothyroxine rarely restores active thyroid hormone, and that thyroid hormone conversion is critical but ignored. The post invites readers to the author's hypothyroidism video course and community.
The author says coffee helps maintain a healthy gut microbiome, reducing gut leakiness and the inflammatory effects of bacterial endotoxins. The post quotes a paper on coffee, gut microbiota and non-alcoholic fatty liver disease. The embedded earlier post says coffee lowers lipogenic enzymes such as fatty acid synthase, and links fatty acid synthase to cancer.
The post quotes Ray Peat saying hypothyroidism raises estrogen and nitric oxide and lowers serum osmolarity, and that several agents can correct the fluid imbalance in Ménière's disease. It adds a quoted paper excerpt associating thyroid diseases with Ménière's. The embedded earlier post gives study abstracts on thyroid hormone use, pregnancy and the menstrual cycle in Ménière's disease.
The post quotes Ray Peat saying estrogen alters immune function, shrinks the thymus and raises antibody production, linking this to allergies. It adds a paper excerpt that estrogen treatment causes thymic atrophy. The embedded earlier post claims hypothyroidism shrinks the thymus and cites a rat study using antithyroid drugs.
The author asserts that polyester underwear makes men infertile and shrinks the testicles. The post quotes a paper proposing a theory that an electrostatic field from polyester underpants disturbs testicular function, with diminished spermatogenesis in dogs. The embedded earlier post reports an association between higher omega-6 intake and smaller testicular volume in young Spanish men.
The post is a Ray Peat quote arguing that TSH acts on many non-thyroid cell types, and that there is no basis for a lower limit of the normal TSH range unless very low TSH is shown to be harmful. It cites the longevity of pituitary-deficient animals as a counterpoint. The embedded quoted post (lowmegatron) claims upper-half 'normal' TSH is linked to metabolic syndrome and that TSH is inflammatory.
The post excerpts a case report of a 54-year-old hypothyroid woman with paroxysmal atrial fibrillation whose palpitations and AF episodes reportedly improved after 6 weeks of levothyroxine. It notes that hypothyroidism may contribute to arrhythmia and that excess thyroid hormone also causes Afib. The embedded quoted post (lowmegatron) gives a Ray Peat quote on nutrients and hormones affecting atrial fibrillation.
The post excerpts a study reporting that honeybees rewarded with caffeine were three times as likely to remember a floral scent as those rewarded with sucrose alone. The embedded quoted post (lowmegatron) claims sleep loss increases pain sensitivity and caffeine reduces it.

The post claims rosacea and other skin conditions are often due to gut events, citing a Ray Peat quote on bacterial endotoxin and a case report of rosacea remission after reduced bowel transit time. The embedded quoted post (lowmegatron) lists conditions attributed to endotoxin from leaky gut and a long list of substances said to help with endotoxin.
The author says all thyroid blood tests can be misleading and TSH is the worst. They support this with a Ray Peat quote that stress hormones lower TSH, so stressed, tired people can have very low TSH. They add an unnamed quoted sentence that short-term fasting and high-dose glucocorticoids suppress serum TSH in healthy subjects. The embedded lowmegatron post says stress lowers TSH, making it an unreliable marker of thyroid hormone activity.
The author promotes the Hypothyroid Masterclass, a video course with a support community covering practical testing, nutrition and dosing concepts. The post mainly lists the module titles. The embedded lowmegatron post contains only an emoji and a link.
The author gives an update on their near infrared light/thyroid antibodies experiment. The blood test sample was damaged in the post, another will be sent, and results are expected in about a week. The embedded lowmegatron post describes the device's arrival and a first 2-minute session per side of the thyroid, with a plan to increase to 8 minutes per side every other day.
lowmegatron replies in his thread about his near-infrared light and thyroid antibodies experiment, saying "The article is here" with a link. The linked content is not supplied.
The author states that depression is a state of low brain energy that can be caused by low thyroid hormone. The embedded lowmegatron post says depression is a common, often overlooked symptom of hypothyroidism. It says blood tests do not reflect tissue or brain status, and it quotes literature and a historical case of hypothyroid psychosis that improved with thyroid treatment.
The post quotes unnamed speakers saying slightly higher CO2 may protect against radiation-related oxidative damage, at least in tissue culture. It also quotes a description of how bicarbonate from dissolved CO2 alters the DNA oxidation reaction, so the hydroxyl radical is replaced by a less damaging radical that targets only guanine. A bracketed title refers to an E. coli and human study.
The author states that bacterial endotoxin causes fear, anxiety, anhedonia, depression, social isolation and decreased empathy, and points to a thread of 'solutions'.
lowmegatron states that women injected with endotoxin (LPS) showed less empathy for others' pain than those given placebo. He suggests low-grade inflammation may reduce empathy as an energy-conserving strategy, and describes endotoxin as a bacterial component that usually comes from a leakier gut and interferes with cellular energy production.
lowmegatron states that endotoxin reduces the ability to experience pleasure in women.
lowmegatron says depressive and anxious behaviours in rats relate to the amount of endotoxin given, and that endotoxin impairs memory. He quotes a study reporting endotoxin-induced elevations in depression, anxiety and memory deficits.
lowmegatron claims researchers identified a brain region (the DVC) associated with social withdrawal and depression that is affected by endotoxin.
lowmegatron says bats given endotoxin showed social isolation behaviors, quoting a study that sickness behaviour decreased the number of contact calls produced by isolated vampire bats.
lowmegatron says endotoxin decreases social exploration, defines the term, and adds in brackets that thyroid hormone T3 increases exploratory behavior.
lowmegatron claims endotoxin-induced "sickness behavior" can be reduced by vitamin E (alpha-tocopherol). He quotes a mouse study in which endotoxin reduced social behavior at 4h and the lowest endotoxin dose's effect was blocked by alpha-tocopherol.
lowmegatron says COX enzymes convert PUFAs such as arachidonic acid into inflammatory molecules like prostaglandins. He quotes a study excerpt stating that endotoxin-induced depressive and anxious-like behavior was mostly reversed by COX inhibitors.
lowmegatron claims COX inhibition and vitamin E improve endotoxin-induced mood and behavior problems largely by preventing the creation of inflammatory PUFA byproducts.
lowmegatron claims the behavioral effects of endotoxin are observable across generations. He quotes a study excerpt saying adult offspring of the maternal endotoxin group showed increased anxiety on the elevated plus maze.
lowmegatron quotes a study excerpt in which offspring of the maternal endotoxin group showed reduced activity in a social interaction test. The excerpt interprets this as increased fear.
lowmegatron says animal experiments show these effects can reverse quickly when endotoxin levels fall. He quotes an excerpt stating endotoxin caused a transient suppression of social interaction that was gone 24 hours later.
lowmegatron claims fat-soluble vitamins D, A, E and K2 can help with endotoxin-related leaky gut, TLR4 activation, inflammation, cortisol and sickness behavior. He lists food sources and the personal regimen he follows (D3 4k IU in winter, K2 8 mg, vitamin E 200-800 IU, vitamin A 1700 ug), and adds that individual needs may differ.
lowmegatron lists factors he claims help control endotoxin. These include optimizing T3, coffee (including decaf), a low omega-6 diet, vitamin C, aspirin, fixing sleep and circadian disorganization, activated charcoal, naringenin, benfotiamine, glycine, aged cascara sagrada, cooked mushrooms, progesterone, pregnenolone and zinc.
The author links brain fog to thiamine (B1) and thyroid hormone status. They quote Ray Peat's anecdote of B1 relieving brain fog and quote two papers on B1 deficiency symptoms and brain fog in hypothyroidism. They add that T3 and B1 are essential for carbohydrate metabolism and that caffeine can raise glucose oxidation in some contexts. An embedded quoted post from lowmegatron claims T3 augmentation has antidepressant effects tied to brain energy.
The author says Ceylon cinnamon was their most useful supplement for regular migraine and they still use a little daily. They summarize a randomized double-blind placebo-controlled trial of cinnamon 600mg three times daily for 2 months, which reported reduced migraine frequency, severity, duration, IL-6 and nitric oxide. They also say keeping blood sugar up, optimizing T3 and raising progesterone relative to estrogen are usually most important.
The author asks why antihistamines help their motion sickness. They quote Ray Peat on histamine, parasympathetic activity and nausea, and quote a study on vitamin C and seasickness. The study reported symptom suppression in women and men younger than 27, increased histamine with wave exposure, and increased DAO with vitamin C. The author also notes a Polynesian custom of eating vitamin C-rich fruit before surfing.
The author argues that in people without a thyroid, levothyroxine-only dosing suppresses TSH relative to blood and tissue T3, so TSH is a poor marker of T3 sufficiency. They cite two PMIDs (a human study on TSH-suppressive dosing and an animal thyroidectomized rat study) and explain tissue-specific T4-to-T3 conversion. An embedded lowmegatron post says TSH is misleading, with a Ray Peat quote on stress lowering TSH and a statement on fasting and glucocorticoids.
The author argues that sleep disruption raises stress hormones and free fatty acids, which impair insulin signaling and predispose to type 2 diabetes. The post quotes a sleep-restriction study excerpt in healthy young men. The embedded quote, from lowmegatron, cites a hypothyroid sleep study on reduced stage 3 and 4 sleep and desiccated thyroid.
The author states that bacterial endotoxin decreases empathy and causes anhedonia in women and includes a link. The embedded lowmegatron post lists endotoxin-associated fear, anxiety, anhedonia, depression, social isolation and reduced empathy, with a solutions thread.
The author says endotoxin lowers testosterone by impairing cellular energy production, quoting mouse and Leydig cell mitochondria research. The embedded lowmegatron post says endotoxin raises cortisol and cites human study data.
The author asks whether avoiding PUFAs and running long distance lowers hypothyroid risk, quoting Ray Peat that a person relatively free of PUFA recovers quickly from prolonged stress. It also quotes studies on exercise intensity and thyroid hormones and on energy availability in exercising women. The embedded lowmegatron post describes a walking trial in postmenopausal women.
The author claims Wi-Fi and cell-signal EMF trigger lipid peroxidation, contributing to several diseases, and that zinc and vitamins C/E help protect cells; the author recommends distance. The embedded lowmegatron post links higher coffee intake to lower cirrhosis risk and lists proposed mechanisms.
The author states that prolactin is a cause of persistent headaches, migraine and cluster headaches, and points to a thread.
lowmegatron quotes the stated objective of a systematic review of preclinical studies on prolactin signaling in headache and migraine pathophysiology.
lowmegatron quotes an abstract stating migraine features are sex-dependent and vary across a lifetime, implicating the hypothalamus-pituitary-gonadal axis, in which prolactin is a key regulator.
lowmegatron quotes an excerpt stating prolactin receptors are present in the trigeminal pain pathway and prolactin induced migraine-like behavior in rodents.
lowmegatron quotes an excerpt stating prolactin signaling has a crucial role in CGRP release, and that prolactin gene deletion attenuated CGRP-induced migraine-like behavior.
lowmegatron quotes a case report of a man with 27 years of severe migraine who had a prolactin-secreting pituitary microadenoma. The report says bromocriptine treatment gave complete and lasting resolution of the migraine.
lowmegatron quotes a case description of a 17-year-old boy with 3 years of recurrent, sharp left retro-orbital headaches lasting under 30 minutes.
lowmegatron quotes the case continuation: the headaches disturbed the boy's food intake and he lost 8 kg. Indomethacin and zolmitriptan were ineffective, and there were no remission periods.
lowmegatron quotes a case report in which a patient's prolactin was 27,450 mIU/L (normal 54 to 381), with otherwise normal pituitary function, and was diagnosed with a prolactinoma.
lowmegatron quotes a case report stating that cabergoline made the patient asymptomatic, that MRIs at 2 and 7 months showed the prolactinoma shrinking, and that he was free from headache attacks for 2 years.
lowmegatron quotes a study of the diurnal rhythm of prolactin and the prolactin and TSH responses to TRH in 31 cluster headache patients and 14 healthy controls.
lowmegatron quotes study conclusions suggesting altered regulation of prolactin secretion in cluster headache periods and symptom-free intervals, and that sleep, estradiol, testosterone, medication, pain, and serotonergic and dopaminergic mechanisms are discussed.
The author introduces a thread on lowering excess prolactin and lists conditions and symptoms attributed to high prolactin. The lowering methods themselves are not in the retrieved text.
lowmegatron advises optimizing thyroid to lower prolactin. He claims low thyroid hormones increase TRH stimulation of prolactin and that subclinical hypothyroidism is associated with elevated prolactin. He quotes a study in which hypothyroid cases had lower total testosterone and free T4 and higher prolactin.
lowmegatron advises keeping parathyroid hormone under control. He quotes a finding that intravenous parathyroid hormone infusion rapidly and markedly raised plasma prolactin in normal subjects.
lowmegatron lists what he calls common causes of elevated parathyroid hormone: calcium insufficiency, magnesium deficiency, vitamin D deficiency, excessive phosphate intake, a low calcium-to-phosphate ratio, and fluoride. The quoted context is a claim that properly regulated calcium protects against allergies, cancer and heart attacks, with parathyroid hormone central to that regulation.
lowmegatron advises minimizing stress, claiming short-term stressors spike prolactin and long-term stress can keep it chronically elevated. He quotes a study that exhaustive exercise lowers select thyroid hormones 24 hours into recovery and that prolactin increases are directly related to TSH changes.
lowmegatron gives a list of claimed ways to lower serotonin. He says PUFAs, estrogen, vitamin E or B1 deficiency and elevated free fatty acids raise it. He says zinc, niacinamide, aspirin, creatine, gelatin/glycine, vitamin E, vitamin D, L-theanine, inosine, coffee with food, calcium, magnesium, aged cascara sagrada, quinine, lysine and ginger lower it or help. He names antiserotonin drugs lisuride, cyproheptadine, memantine and famotidine.
lowmegatron quotes a statement that fenfluramine releases serotonin, that serotonin stimulates prolactin secretion, and that serum prolactin therefore reflects endogenous serotonin.
lowmegatron advises minimizing estrogen and estrogenic exposures. He quotes a source saying estrogen increases pituitary prolactin-secreting cells (per autopsy studies) and prolactin gene transcription and mRNA.
lowmegatron continues the quote, saying estrogen changes the pituitary's response to factors affecting prolactin release: it lessens dopamine's inhibitory effect and heightens the response to TRH.
lowmegatron advises checking for medications that raise prolactin. He quotes a source naming SSRIs, MAO inhibitors, some tricyclics, prokinetics, opiates, estrogens, anti-androgens, antihypertensives, some H2 antagonists, anticonvulsants and cholinomimetics as capable of causing hyperprolactinemia.
lowmegatron advises choosing saturated fats, claiming omega-6 fatty acids can increase prolactin. He quotes a study suggesting arachidonic acid metabolism, with lipoxygenase products partly responsible, is involved in basal and TRH-stimulated prolactin secretion.
lowmegatron advises getting adequate sodium. He quotes a study in which sodium-deprived animals had increased aldosterone secretion and higher plasma and pituitary prolactin than controls.
lowmegatron says aspirin minimizes stress-induced prolactin increases, quoting a study finding a significantly reduced total prolactin response to stress after aspirin. He notes the study used 800 mg and suggests lower doses may work in most cases (his opinion).
lowmegatron says hundreds of milligrams of vitamin B6 (pyridoxine) have been used in many studies to lower prolactin. He quotes a study in which prolactin fell to 42% of baseline in children evaluated for short stature.
lowmegatron says high-dose B6 can cause neuropathy and that lower doses of the P5P form may effectively lower prolactin. He recommends Chris Masterjohn's blog article on the topic for anyone considering high-dose B6.
lowmegatron claims melatonin increases prolactin and that bright light early in the day may lower it. He quotes a source saying bright light during early darkness delays the nocturnal melatonin peak and alters cortisol, GH, prolactin and vasopressin secretion.
lowmegatron says vitamin E has anti-estrogen and anti-PUFA effects. He quotes findings that vitamin E lowered prolactin in uremic hemodialysis patients and inhibited pituitary hypertrophy in vitamin E-deficient rats, noting 300 mg/day for eight weeks.
lowmegatron calls zinc a key nutrient for optimizing prolactin. He quotes a study in which zinc-treated patients had higher plasma zinc and lower serum prolactin, with an inverse relationship between the two.
lowmegatron says progesterone minimizes estrogen-induced prolactin and has anti-serotonin effects. He quotes a source saying progesterone is converted to 5α-DHP in the pituitary, which inhibits estrogen-induced prolactin release similarly to progesterone.
lowmegatron reports that a Tribulus terrestris extract lowered prolactin by over 50% in four weeks in infertile men. The study used Androsten (250 mg dried extract per capsule).
lowmegatron describes his own elevated prolactin (600 mIU/L, about 28 ng/mL) lasting a few months, which he says resolved with incandescent lighting at his workspace, 10 mg P5P after breakfast and 4 g creapure creatine daily. He says it also seemingly worked for two other people.
The author argues that polyester on the genitals affects fertility, citing dog, rat and human studies with quoted excerpts showing reduced sperm, low progesterone and failed conception, largely reversible after removal. The embedded lowmegatron post says polyester underwear makes men infertile and shrinks the testicles, and quotes an electrostatic field theory.
The post quotes Ray Peat saying the prolactin 'normal range' has been expanded upward and that the lower range was better for judging health, and he attributes the change to population shifts from estrogen and PUFA. It embeds lowmegatron's post listing effects of high prolactin.
Author says a mouse study found high dietary omega-6 (n-6) PUFA induces nerve dysfunction and chronic pain resembling peripheral neuropathy, and that benfotiamine (vitamin B1 form) may help. Author quotes papers on PLA2-driven fatty acid release, benfotiamine's anti-inflammatory effects in macrophages, and a benfotiamine dose trial in painful diabetic neuropathy. The embedded quoted post claims sleep loss increases pain sensitivity and caffeine reduces it.
Author says thyroid antibodies (anti-TPO) are higher in women with melasma and higher still in severe cases, and that estrogen may be involved. Author quotes papers on estrogen and autoimmune thyroid disease and on sex steroid regulation of melanin synthesis via GPER and PAQR7, plus quotes from Ray Peat and Hippocrates. The embedded quoted post claims light is the most effective treatment for Hashimoto's.
Author claims stress releases free fatty acids, omega-6 fats raise plasma serotonin, and migraine results. Author says keeping blood sugar up (e.g., orange juice) can prevent the free fatty acid rise, and that serotonin blockers like cyproheptadine can help. Author quotes a migraine study on free fatty acids, platelet serotonin and linoleic acid. The embedded quoted post claims cyproheptadine reduced migraine frequency by about 75%.
Author states hypothyroidism is a cause of hyperpigmentation, supported by a Ray Peat quote linking melasma to estrogen excess, energy depletion and thyroid function, and a case report of pigmentation improving after levothyroxine. The author's 🙄 appears to express skepticism about the case report's "no apparent clinical symptoms" wording. The embedded quoted post is the earlier melasma/thyroid antibody post.
Author claims hypothyroidism lowers testosterone, shrinks testicles and causes male infertility. Author backs this with quotes from Ray Peat and Broda Otto Barnes, rodent experiments (PTU-induced hypothyroidism, rdw rats with thyroxine treatment), a Nigerian cross-sectional study of infertile men, and a prospective controlled study on sperm morphology. The embedded quoted post claims TSH/T4 and even T3 tests are limited and that T3-activating cells matter.
The post reproduces Ray Peat's text on learned helplessness, covering Seligman's work, Richter's rat 'hopelessness' studies and MKUltra context. It adds the statement that T3 has been identified as able to help reverse learned helplessness. It also includes a Facebook comment describing depression lifting after starting Cynoplus with extra T3.
lowmegatron promotes his Hypothyroid Masterclass for people told their labs are normal who still feel hypothyroid. He lists on-demand modules on thyroid testing, conversion, supplementation, nutrition, stress and thyroid-affecting drugs, and mentions a support community.
The author says vitamin C supplementation lowered TSH and improved symptoms in people on levothyroxine, citing a small proof-of-concept study. The author also says vitamin C may aid levothyroxine absorption and protect the thyroid from lipid peroxidation. The author personally thinks whole-food vitamin C is safer. The embedded quote is a Ray Peat statement on TSH.
The author asserts that subclinical hypothyroidism is associated with insomnia and poor sleep, and that 'there is no such thing as subclinical'. The post quotes a cross-sectional study abstract, Ray Peat on T3, magnesium and sugar restoring brain energy, and an all-night sleep study in hypothyroid patients. The embedded post repeats the sleep study and Peat material.
The author says the 5-HT3 blocker ondansetron reverses learned helplessness in rodents, but only at low to moderate doses. The author says ginger compounds are also 5-HT3 antagonists and that serotonin is elevated in learned helplessness and hypothyroidism. The post quotes a rat study abstract.
The author reports a new study that describes orange juice's protective mechanisms against cardiovascular disease, stroke, type 2 diabetes and obesity. The study found that chronic OJ consumption alters gene expression related to inflammation, blood pressure and metabolism, with effects varying by body weight. The embedded earlier post reports that OJ improved HOMA-IR and gut microbiota in young women.
Post quotes Ray Peat saying enlarged eye vessels, especially with yellow around them, suggest B vitamin (especially B2) deficiency. He says there are no really safe B2 supplements, so weekly liver would be reasonable.
Author claims frequent undereating leads to fat gain even in athletes, via lowered metabolic rate and thyroid hormone changes. Supports this with quoted correlations from a study of elite female gymnasts and runners. The embedded lowmegatron post claims prolonged exercise lowers T3 and raises rT3, and that glucose blunts this.
Post poses a question about substances or activities that help induce deep sleep and answers with a Ray Peat quote naming thyroid hormone, vitamin D, calcium and magnesium. The embedded lowmegatron post links subclinical hypothyroidism to insomnia and quotes Peat and a hypothyroid sleep study.
Post quotes Ray Peat saying hypothyroidism involves poor absorption and retention of magnesium, sodium and copper. He says extra sodium raises body temperature, lowers aldosterone, helps retain magnesium and improves cell response to thyroid hormone. He adds that low sodium raises adrenaline while enough sodium lowers adrenaline and improves sleep.
Author says increasing fruit fructose led to 50% greater weight loss in a six-week low-calorie diet trial. Author also says fructose limits muscle wasting and thyroid hormone depletion from dieting, citing an IV fructose protein-sparing study. The embedded lowmegatron post describes fructose infusion during a 10-day fast in obese people.
The author claims zinc is overlooked in thyroid status and may independently contribute to hypothyroid hair loss. He cites studies on zinc preventing exercise-related drops in thyroid hormones, zinc opposing melatonin's thyroid suppression, and zinc raising T3. He speculates zinc helps T4-to-T3 conversion.
Author claims more sodium means longer lifespan and better health, quoting a study of country-level sodium intake correlating positively with life expectancy and inversely with all-cause mortality. The embedded lowmegatron post quotes Ray Peat on sodium loss in hypothyroidism and sodium and CO2 supporting ATP.
Post quotes Ray Peat saying learning changes biology, brain structure and the meaning of past experience. The content is general and philosophical, with no specific health intervention.
Author reports a small human trial in which T3 gave greater weight loss and lower cholesterol than T4/levothyroxine at doses keeping TSH within 0.5-1.5. The author does not read this as meaning everyone needs T3 alone, saying a combination is best for most people who need thyroid hormones and that others should aim to increase thyroid hormone conversion.
Post presents Ray Peat's claim that US doctors fail to correct hypothyroidism by prescribing T4 instead of T3, and that hypothyroid women are more likely to get cancer. It then quotes an observational study of 23 end-stage cancer patients in whom induced low T4 with T3 was associated with survival beyond expectation.
The author quotes Ray Peat on light, winter sickness and estrogen dominance. Peat claims a lack of bright light causes progesterone deficiency, leaving estrogen and prolactin unopposed. He also links this to unsaturated fats and tryptophan and says thyroid supplement needs can be four times higher in December than in July.
The post says coffee intake is associated with lower colorectal cancer mortality, with 4 or more cups per day linked to 30% lower overall death and 52% lower cancer-specific death. It quotes cohort and mechanism papers. The embedded lowmegatron post claims coffee reduces lipogenic enzymes such as fatty acid synthase.
The post claims hypothyroidism raises stress hormones and histamine, contributing to anxiety, hypertension, blood sugar problems and depression. It cites experimental hypothyroidism data, a T4/T3 combination therapy study and a rat mast cell study.
The post quotes Ray Peat saying a few doses of progesterone can shift the balance, activating the thyroid and liver and stabilizing blood sugar so glucose is available for T4-to-T3 conversion.
The post claims 'eat less, move more' lowers T3 and raises reverse T3, citing Army Ranger training data. It says TSH can miss low tissue T3. The embedded lowmegatron post quotes Ray Peat that stress hormones lower thyroid conversion and TSH alone is inadequate.
The post says bacterial endotoxin disrupts thyroid hormone levels and labs, lowering T4, T3 and TSH and raising reverse T3, citing a study of 24 healthy people. The embedded lowmegatron post claims orange juice with a high-fat, high-carb meal lowered endotoxin and metabolic stress.
The post combines a Ray Peat quote on fruit juice/Coca-Cola with excerpts on intranasal CO2, orange juice, hypoglycemia, fasting and caffeine in migraine. It states caffeine seems to worsen migraine in a minority. The embedded lowmegatron post links stress, free fatty acids, linoleic acid and serotonin to migraine.
The post quotes Ray Peat saying hypothyroidism causes thymus atrophy, partly from lack of thyroid hormone and partly from excess estrogen and cortisol. The embedded lowmegatron post adds thymus function context and a rat study.
The post claims magnesium improves learning and memory, quoting a paper in which magnesium-L-threonate raised brain magnesium and enhanced learning and memory in rats.
The post says birth control pill use is associated with higher hypothyroidism risk, rising with duration. It cites a study of 5116 women in which use over 10 years had OR 3.837. The embedded lowmegatron post quotes Ray Peat on fiber, bowel function and estrogen clearance.
The sharing account posts a Ray Peat quote saying cold hands and feet, and oral temperature, can indicate thyroid function without a blood test, with cold extremities being the first sign of failing thyroid function. The embedded post by lowmegatron claims hypothyroidism raises stress hormones and histamine and that T3 added to T4 therapy improves anxiety, depression and quality of life.
The post contains only a t.co link and quotes BalancedBM announcing that "the P5" has arrived and that all orders ship the next day. No health claims are visible.
The post shares a quoted passage saying thyroid hormone transport across the blood-brain barrier in hypothyroid patients is clinically important but poorly understood, and that T3 may be better than T4 for myxedema coma because it crosses more rapidly and completely into cerebrospinal fluid. The embedded lowmegatron post says T4-only treatment in poor converters probably starves the brain of thyroid hormone, citing monkey experiments.
The author claims hypothyroidism can cause SIBO, which reduces lactase and can lead to lactose intolerance via slowed gut transit and reduced stomach acid. The post supports this with a Ray Peat quote and two PMID excerpts: one on bacterial supernatant reducing sugar-splitting enzymes, one on a higher rate of positive breath tests in patients with a history of hypothyroidism.
The author claims hypothyroidism causes water retention ("hyperhydration") and the characteristic puffy look by disrupting extracellular water regulation. The post quotes an abstract (PMID 3823017) on 15 hypothyroid patients showing extracellular hyperhydration with fluid accumulating in the interstitial space.
The author shares a Facebook commenter's account of decades of CFS/ME diagnosis that the commenter says was Hashimoto's hypothyroidism. The commenter reports that T4 was nearly useless but natural desiccated thyroid gradually resolved symptoms, and urges testing FT3. The author frames it as another person misdiagnosed with CFS when the cause was low thyroid hormone. The embedded quoted post from lowmegatron claims CFS patients have lower T3 and higher reverse T3 despite normal TSH.
The author claims probiotics can cause brain fog, bloating and SIBO, that people may be unknowingly harming themselves, and that antibiotics are sometimes needed. The author quotes a study abstract (PMID 29915215) describing brain fog with SIBO and D-lactic acidosis that improved after stopping probiotics and using antibiotics. The embedded quoted post from lowmegatron links vitamin C deficiency, endotoxin and cognitive impairment.
The author claims magnesium reduces stress, anxiety and depression, with effects noticeable in two weeks and scores halving by six weeks. The author cites a study of 248 mg magnesium from magnesium chloride and quotes an abstract (PMID 28654669) on an open-label randomized cross-over trial in 126 adults with mild-to-moderate depression symptoms.
The author claims hypothyroidism with fast heart rate, high blood pressure and palpitations can be caused by high TRH. The author quotes Ray Peat on TRH effects, explains that TRH is elevated in primary hypothyroidism, and quotes a pharmacology passage on TRH pressor and tachycardic effects. The embedded quoted post from lowmegatron claims hypothyroidism raises stress hormones, blood pressure and histamine.
The post quotes Ray Peat recommending carbohydrate (preferably sugar), salty foods, bedtime T3 or ice cream to reduce nighttime stress hormone reactions. It also quotes a 1967 study excerpt that hypothyroidism reduces stage 3 and 4 sleep and that desiccated thyroid may increase them. The embedded quoted post from lowmegatron links subclinical hypothyroidism to insomnia.
The post quotes Ray Peat saying that women who feel anxious or shaky from small amounts of coffee, which they attribute to hypoglycemia, often have fewer symptoms with about two ounces of coffee with cream or milk alongside a meal. The embedded quoted post, from lowmegatron, cites cohort data associating coffee intake after colorectal cancer diagnosis with lower mortality, and lists proposed mechanisms.
The author claims Ray Peat's carrot salad can lower estrogen by reducing colonic reabsorption, pointing to a laxative transit study. The post quotes that study's excerpt, then describes Peat's recommended preparation with oil and vinegar. The embedded quote, from lowmegatron, is a Ray Peat quote about raw carrot or cooked mushrooms stimulating peristalsis and limiting bacterial toxin production.
The author reports that their thyroid testing company failed them again after nearly 10 years without problems, because samples taken overseas had too long a transit time. They have ordered a test from a company that says it has nearer labs. The embedded quote is an earlier self-experiment with a device used near the thyroid.
The post quotes Ray Peat on accumulated unstable fats making endotoxin exposure more inflammatory and stressing the lipid-rich brain with age. The embedded quote, from lowmegatron, lists conditions attributed to endotoxin from leaky gut and a long list of nutrients, drugs and habits said to help.
The author argues that oxidized LDL drives atherosclerosis and related cardiovascular events, and that linoleic acid from seed oils is oxidized by lipid peroxidation, which hypothyroidism increases. The post quotes Ray Peat on Broda Barnes' rabbit work and thyroid supplementation, plus excerpts from two papers on LDL oxidizability and thyroid function. The embedded quote, from lowmegatron, claims raised blood free fatty acids cause inflammation and impair artery dilation.
Author describes a randomized, double-blind crossover trial of substituting T3 (liothyronine) for T4 (levothyroxine) in hypothyroidism. They report greater weight loss and lower LDL, total cholesterol and apolipoprotein B at equivalent TSH suppression. They add that high cholesterol usually indicates another disease process, here hypothyroidism.
Author asks 'What are they training for?' while sharing a quoted post by KruseYouri labelled 'Chinese strength training, 1938'. No health claim is stated.
Author states that low-calorie dieting increases cortisol and lists harms of high cortisol. They quote a paper saying 1200 kcal restriction increased cortisol output and perceived stress, and that clinicians may need to rethink recommending dieting.
Author comments 'Jeff was born for this' while sharing lowmegatron's post on low-calorie dieting and cortisol. The comment is context-dependent, and no explicit support for the quoted claims is given.
Author says choosing the right types of fat is key to getting and staying lean, and points to a thread. The retrieved text does not contain the thread's content.
lowmegatron claims seed oils increase feed efficiency by 20% in rats compared with coconut oil, with seed-oil-fed rats eating less but gaining more weight. He notes coconut oil is mostly saturated while seed oils are polyunsaturated.
lowmegatron says women who ate extra virgin olive oil at breakfast lost almost twice as much fat as those who ate the same amount of seed oil. In his opinion, the main effect comes from reducing seed oil, whose linoleic acid he says suppresses metabolism.
lowmegatron says men with fatty liver disease lost more weight using olive pomace oil instead of seed oils, and that more dietary linoleic acid meant less weight loss.
lowmegatron cites an analysis of 9 human studies showing reduced body fat percentage and BMI with coconut oil. He quotes Ray Peat: the anti-obesity effect of coconut oil is clear in all animal studies and in friends who eat it regularly.
lowmegatron claims cacao/cocoa butter increases metabolism via its saturated fatty acid, stearic acid, which he says increases mitochondrial fusion and thereby improves mitochondrial function and energy efficiency.
lowmegatron claims stearic acid reduces fat and raises lean mass in mice, probably through anti-cortisol and anti-estrogen effects. He reports personally losing fat after replacing some dietary fat with cacao butter (about 30% stearic acid) while keeping his diet otherwise consistent.
lowmegatron claims polyunsaturated fats impair thyroid hormone metabolism, liver function, glucose oxidation and cardiolipin, and tend to raise metabolism-lowering hormones. The quoted earlier post cites a chicken study passage stating PUFA inhibit T4-to-T3 conversion in mammals and impair T3 binding to nuclear receptors.
lowmegatron advises swapping unsaturated fat for saturated fat, stating he eats 15g of fat with each of four meals for maintenance or fat loss, aiming for a higher saturated-to-polyunsaturated ratio.
lowmegatron lists fats he calls pro-metabolic (coconut oil, cocoa butter, butter/ghee, cream and cheese, palm oil, beef tallow) and polyunsaturated oils to minimize (soybean, canola, sunflower, peanut, cottonseed, corn, safflower, grapeseed, flax, hemp, chia, evening primrose, fish oil).
Author asks whether others have had similar effects from cacao butter. Author reports less belly fat, deeper sleep, a cognitive boost, better digestion and fewer panic attacks, and says it increases their metabolism and causes slight weight/fat loss when swapped for other fats.
Author describes brexanolone, an IV allopregnanolone treatment for postpartum depression costing $30-40,000, and notes allopregnanolone is downstream of pregnenolone and progesterone. The post quotes Ray Peat on progesterone's conversion to allopregnanolone and mood effects. It also quotes a paper (PMID 32250509) hypothesizing that oral progesterone could raise allopregnanolone and relieve postpartum depression at far lower cost, with further studies needed.
Author says thyroid hormone markers differ in depression but are often ignored. Standard testing focuses on TSH and T4, yet T4 must convert to T3, and many people convert poorly. Depression is associated with low T3, and a raised TSH may be dismissed if T4 is normal. Quoted study excerpts report lower T3 and higher TSH across depression severity grades and suggest thyroid evaluation before antidepressant therapy.
Author says up to half of the population is vitamin D deficient, which can lead to cardiovascular calcification by raising parathyroid hormone. Author states they need about 4,000 IU/day to keep levels at 50-60 nmol/L in winter. A quoted excerpt (PMID 19055985) links vitamin D deficiency to cardiovascular risk, hypertension, insulin resistance and parathyroid hormone elevation. The embedded quote gives Ray Peat's winter vitamin D practices.
Author states hypothyroidism increases adrenaline, quoting Ray Peat on adrenaline sustaining blood sugar and body temperature while disturbing sleep and speeding the heart. A quote from PMID 4766338 says thyroid hormone depresses noradrenaline and adrenaline secretion by blocking production at the cellular level. The embedded post from lowmegatron claims experimental hypothyroidism raised stress hormones and histamine, and that adding T3 to T4 improved anxiety, depression and quality of life.
Quoted Ray Peat passage arguing that standard thyroid blood tests (T4, TSH) use ranges so wide that nearly everyone counts as normal. He says this traces to the protein-bound iodine test, later shown not to reflect thyroid function, and that the doctrine that only about 5% of people are hypothyroid persisted anyway.
The author says hypothyroidism nearly doubles dementia risk and that the association is worse in people on thyroid medication. They suggest T4-only medication and a lack of diet/lifestyle guidance as the likely reasons, and link lipid peroxidation from insufficient T3 to neurodegeneration. The embedded quoted post mentions a Ray Peat anecdote about dementia recovery with increased body temperature.
The author says caloric restriction, fasting and low-carb diets reduce thyroid hormone conversion, favoring reverse T3 over T3, and advises eating regularly, enough, and eating carbs. The embedded quoted post says low-calorie dieting increases cortisol, with a list of harms and study excerpts.
The author reports sleeping much better after a big bowl of fruit with some salt right before bed. The embedded quoted post links sleep disruption to elevated stress hormones, free fatty acids and reduced insulin sensitivity.
The author says subclinical hypothyroidism can elevate prolactin and cause galactorrhea, and presents a quoted case report of a woman whose galactorrhea resolved and prolactin normalized after levothyroxine. The embedded quoted post begins a thread on lowering excess prolactin and lists effects of high prolactin.
The author says excessive cell phone use is associated with higher TSH and lower thyroid hormones in students, and that 900 MHz EMF lowered TSH and thyroid hormones in rats. They recommend keeping distance from the thyroid/brain, using hands-free or a wired headset.
The author says creatine supplementation improves memory and cognition in the elderly, with 5 g/day improving results in a couple of weeks. They quote a study whose authors discuss ATP resynthesis as a possible mechanism but say energy supply may not be the major factor.
The author says obese women on levothyroxine have lower resting metabolic rates than obese women not on levothyroxine with similar TSH. They argue levo-only therapy does not fully correct metabolism and normal TSH is a poor marker of thyroid hormone metabolism. The quoted post (lowmegatron) says caloric restriction, fasting and low-carb diets reduce T3 conversion.
The author says people with liver cirrhosis cannot make adequate T3, that most T3 is made outside the thyroid, and that some tissue-produced T3 is invisible to blood tests. They quote a study reporting lower serum and urinary T3 in cirrhosis. The embedded post (lowmegatron) quotes Ray Peat on progesterone and T4-to-T3 conversion.
The author says high-dose zinc supplementation normalized T3 and lowered reverse T3 in people with zinc deficiency, and that zinc deficiency may cause hypothyroid symptoms by impairing T4-to-T3 conversion. The author notes this was a high dose in confirmed zinc deficiency. The embedded post (lowmegatron) lists a thyroid T3 checklist.
The post quotes Ray Peat saying elevated TSH goes with elevated prolactin, that thyroid hormone supplementation usually corrects prolactin, and that calcium and vitamin D help balance prolactin, parathyroid hormone and cortisol. The post author adds that low thyroid hormone raises TRH, which stimulates TSH and prolactin. The embedded quoted post describes a case report of subclinical hypothyroidism with hyperprolactinemia and galactorrhea that resolved on levothyroxine.
lowmegatron promotes his Hypothyroid Masterclass Group, listing video modules on hypothyroidism symptoms and causes, blood tests and their problems, pulse and temperature, T3 activity, autoimmunity, conversion, reverse T3, T4/NDT/T3 supplementation, nutrition (iron, iodine, selenium, PUFA), stress, and drugs affecting thyroid hormones.
The author claims hypothyroidism raises stress hormones (cortisol, adrenaline, noradrenaline, aldosterone) and histamine, contributing to anxiety, hypertension, blood sugar problems and depression. They cite studies in which stopping thyroid medication raised these hormones, and studies in which adding T3 to T4 improved mood and quality of life. A rat study is cited for higher mast cells and histamine.
The author describes a case report of myxedema coma in a woman with 'subclinical' hypothyroidism who was prescribed levothyroxine. She recovered after IV T3, and the author argues that lab ranges missed her condition. The report notes she may not have taken the levothyroxine. The embedded quoted post claims TSH/T4 tests are blind to downstream thyroid hormone issues and that T3-activated cells are what matter.
The post quotes Ray Peat saying sugar craving usually reflects a need for sugar caused by hypothyroidism. The author lists how low T3 shifts metabolism from glucose to fatty acid oxidation and impairs glucose uptake. The embedded quoted post links subclinical hypothyroidism to doubled diabetes risk, citing mouse experiments and NHANES analysis.
The author claims Bluetooth headsets may cause thyroid issues, quoting a paper that linked longer daily use to thyroid nodules. The embedded quoted post links heavy cell phone use to elevated TSH and lower thyroid hormones in students, and cites rat experiments with 900 MHz EMF lowering TSH and T3/T4. It advises distance and hands-free or wired headsets.
The author compiles Ray Peat quotes and cited excerpts arguing that hypothyroidism or low thyroid hormone activity can drive anxiety through raised adrenaline and histamine. The post says T3 added to T4 therapy improved anxiety, depression and quality of life, and that some foods, thyroid or pregnenolone may help. An embedded post by lowmegatron repeats the same thyroid, stress-hormone and histamine claims.
The post quotes Ray Peat on using flowers of sulfur topically or by mouth for yeast, with raw carrot and herbs as alternatives. The embedded lowmegatron post presents excerpts saying estrogen promotes Candida albicans growth and virulence while progesterone may reduce it, noting this mostly concerns vaginal candidiasis.
The author says cyproheptadine is sometimes used for IBS and functional GI disorders, proposing serotonin and histamine blocking plus ACTH dampening as possible mechanisms. The author cites three PMIDs on symptom improvement, exaggerated ACTH response in IBS, and lowered ACTH/cortisol in healthy volunteers. The embedded quoted post gives a Ray Peat quote on low-dose cyproheptadine for insomnia.
The author claims sodium deficiency can cause insulin resistance and rapidly raise noradrenaline and aldosterone. They cite a study (PMID 21036373) where healthy people on a low-salt diet had higher HOMA-IR and 50% higher aldosterone. The embedded Ray Peat quote links sodium intake to aldosterone, magnesium retention, adrenaline and sleep in hypothyroidism.
The author argues that a 1°C lower core temperature, reflecting low thyroid hormone activity, could add about 120 lb over a decade and that hypothyroidism induces a hibernation-like state. The post describes Broda Barnes's basal temperature test and BMR as thyroid indicators, with cited thresholds. The embedded Ray Peat quote criticizes TSH/T4 reference ranges and the history of the protein-bound iodine test.
lowmegatron says Broda Barnes developed the Basal Temperature Test as a substitute for BMR testing, and quotes Barnes claiming it matched other thyroid tests, detected hypothyroidism others missed, and that symptoms resolved as temperature rose with treatment. He adds that many people have low resting metabolism from thyroid hormone issues unrelated to the gland, where diet and lifestyle correction is usually enough.
The author says a study of isocaloric carbohydrate deprivation (2%) lowered T3 about 25% and raised reverse T3, free T4 and T3 uptake, with TSH unchanged. They say this means thyroid hormone conversion fell, and that TSH-based screening could miss it. They also say free fatty acids doubled and interfere with thyroid hormone activity. The embedded post from lowmegatron quotes Ray Peat on sugar craving and hypothyroidism and outlines a low-T3, fatty acid oxidation and glucose oxidation mechanism.
The author shares Ray Peat's view that hypothyroidism and bowel inflammation are key in gout, and that raw carrot salad, aspirin and correcting thyroid function usually resolve it. They cite a paper reporting more hyperuricemia and gout in hypothyroid patients. Further Peat excerpts describe uric acid as an antioxidant and anti-inflammatory defense, and gout symptoms as possibly driven by intestinal endotoxin. The embedded post from lowmegatron reports that coffee intake is associated with lower gout risk.
The author argues that some hypothyroidism is reversible with iodine restriction and that excess iodine is as harmful as deficiency. They cite a study in which 12 of 22 patients became euthyroid after 3 weeks of iodine restriction, and in which reintroducing 25 mg iodine daily made them hypothyroid again. They add Ray Peat and a review on excess iodine and autoimmune thyroiditis. They say selenium or vitamin E reduce the risk but do not fully prevent it. The embedded post from lowmegatron covers iodine intake and hypothyroidism rates in Japan and risk factors for iodine-induced thyroid dysfunction.
The author shares Ray Peat's claim, citing David McCarron's work, that calcium deficiency contributes to high blood pressure through chronically elevated parathyroid hormone. Several PMID excerpts associate lower dietary calcium with hypertension. One excerpt explicitly cautions that the correlations do not prove causation. The embedded post from lowmegatron broadly claims that dysregulated calcium clogs arteries and calcifies soft tissues.
The author claims hypothyroidism causes constipation, citing Ray Peat and a paper reporting a 72% improvement in constipation with T3 plus T4 versus levothyroxine alone. A quoted case describes a 71-year-old woman whose symptoms, including hair loss, improved on T3 and worsened on levothyroxine only.
The author states that SSRI antidepressants create antibiotic-resistant bacteria. They quote a paper reporting that fluoxetine (Prozac) induced multiple antibiotic resistance in E. coli through ROS-mediated mutagenesis, and quote the researcher on environmental persistence of fluoxetine. The author notes it is unknown whether the lab findings affect rates of resistant disease.
The post quotes Ray Peat on meal frequency: frequent meals help during hypothyroidism and help prevent obesity, while 2-4 meals suffice once thyroid and liver work well. Small meals raise metabolic rate and single big meals increase fat storage. The embedded quoted post from lowmegatron argues lower core temperature in hypothyroidism promotes weight gain.
The post quotes Ray Peat on parathyroid hormone, calcium and vitamin D (high calcium intake compensating for low vitamin D, both vitamin D and dietary calcium tending to lower PTH), and on soft-tissue calcification (calciphylaxis) involving estrogen, histamine, serotonin and iron. It notes the image shows a calcified rat from Hans Selye's experiments. The embedded lowmegatron post claims PTH deposits calcium in soft tissues.
The author quotes the Framingham Heart Study paper, which found that lower naturally occurring total cholesterol levels are associated with poorer performance on cognitive measures requiring abstract reasoning, attention, word fluency and executive function.
The author states that body temperature is one of the best markers of thyroid hormone activity and is declining over time, and attributes this mainly to inappropriate diets, pollutants, and underdiagnosis and mistreatment of hypothyroidism. Broda Barnes and a paper on decreasing US body temperature are quoted.
The author claims CO2 absorbed through the skin is effective for some cancers, quoting Ray Peat on baking soda supplying CO2 to tumors, and quoting an in vivo study on transcutaneous CO2 suppressing tumor growth and lymph node metastasis in oral squamous cell carcinoma.
The author presents a case report of myxedema coma in 'subclinical' hypothyroidism: body temperature 93°F, heart rate 58, TSH 59 with a 'normal' free T4; after T4, T3 and hydrocortisone, temperature rose to 98°F and heart rate exceeded 72 over seven days.
The post quotes Ray Peat saying many people become sleepy after eating much carbohydrate and/or salt, that both lower adrenaline, and that carbohydrate can increase thyroid hormone activity and restore tissue energy. A link is included. The embedded lowmegatron post quotes Peat on hypothyroidism raising adrenaline.
The author makes a joking comment ('They weren't sick, just hustling. What's your excuse?') on a quoted post by AbudBakri saying a patient tried to sell research peptides to a nurse.
The author jokes that the Randle Cycle discourse on X is 'its own thing', commenting on a quoted post from hov992 suggesting alternating carb and sugar bites.
Author summarizes a trial in which aloe vera juice was associated with lower TSH and TPO antibodies over 9 months in women with subclinical hypothyroidism and Hashimoto's. Free T3 also fell. The author doubts the authors' explanation for the T3 drop and suggests tracking T3 if trying this.
Post shares a Ray Peat quote saying that mid-range parathyroid hormone is associated with inflammatory and degenerative problems. It says higher PTH goes with more of these diseases, and that enough calcium, then vitamin D, suppresses excess PTH. The embedded post says calcium intake helps lower PTH.
Author says adequate calcium can help keep lead out of the blood, particularly in pregnancy, because low calcium intake raises parathyroid hormone and releases lead stored in bone. The author quotes a paper on calcium supplementation and blood lead in pregnancy and lactation. The embedded quoted post carries Ray Peat quotes on PTH, calcium, vitamin D, milk and calcification.
Post shares a Ray Peat quote saying hibernators fed a saturated, high-carbohydrate diet without nuts do not hibernate, and that serotonin triggering hibernation rises at a certain point of fat unsaturation. The embedded post from lowmegatron advises increasing saturated relative to unsaturated fats and lists fats to eat and avoid.
The author argues that vitamin E supports immune function in aging, citing mouse pneumonia and influenza data and a human study of elderly subjects. The proposed mechanism is partial reversal of age-related T cell decline. The author says they take 200 IU of natural tocopherols and tocotrienols and that synthetic alpha-tocopherol should be avoided. The quoted lowmegatron post says cortisol shrinks the thymus.
The post shares a Ray Peat quote saying regular sleep timing, about six to nine hours a night, is protective and anti-stress, and that prolonged starvation or fasting can shrink the brain. The quoted lowmegatron post links hypothyroidism to reduced deep sleep, citing a 1967 study of 7 hypothyroid patients that reported fewer stage 3 and 4 sleep minutes, with some improvement after desiccated thyroid.
The post shares a Ray Peat quote about learned-helplessness experiments in rats, where rescued rats later swam longer. The embedded lowmegatron post quotes Peat on learned helplessness and stress, says T3 can help reverse it, and includes a Facebook comment describing depression lifting after starting Cynoplus with extra T3.
The post shares a Ray Peat quote that the liver supplies about 70% of active thyroid hormone (T3) and needs adequate glucose to do so, with frequent snacks such as orange juice suggested. It adds a study excerpt (PMID 11167929) reporting that 2% carbohydrate intake lowered plasma T3 and raised reverse T3 versus higher-carbohydrate diets. The quoted lowmegatron post makes similar claims.
The author argues that parathyroid hormone (PTH) and prolactin lower male libido and fertility. Quoted study excerpts describe PTH raising prolactin, cabergoline and metergoline lowering prolactin with improved sexual function or spermatogenesis, and higher prolactin in older men with low libido. The author also lists factors that raise PTH. The embedded post by lowmegatron says adequate calcium may help keep lead out of blood, especially in pregnancy.
The author says a doctor's presence can raise blood pressure and heart rate, so testing location and timing matter. A quoted study excerpt reports that a doctor's arrival raised systolic and diastolic pressure in 48 subjects, with tachycardia. The embedded post by lowmegatron relays Ray Peat and PMID excerpts linking low calcium intake to hypertension.
The author says coffee lowers kidney stone risk by about 10% per 8 oz daily, that the effect is partly through reduced lipid peroxidation, and that it is mostly independent of caffeine. The embedded post by lowmegatron claims that coffee intake is associated with lower cirrhosis risk and lists proposed liver-protective mechanisms.
The author claims vitamin D plus calcium supplementation reduced cancer diagnoses by 60% in older women, citing a 4-year randomized placebo-controlled trial (PMID 17556697). The embedded post by lowmegatron relays Ray Peat quotes on PTH, vitamin D, calcium, milk intake and soft-tissue calcification.
The posting account quotes Ray Peat that thyroid and magnesium are often needed to normalize mitochondria and prevent calcification, and clarifies that 'thyroid' here means T3. The embedded post by lowmegatron shares a Facebook commenter's anecdote of many reported improvements after switching to T3.
Post pairs a Ray Peat quote with two quoted PMID excerpts. Peat says vitamin D deficiency and hypothyroidism produce similar inflammation, with TSH and parathyroid hormone (PTH) driving mast cell activation and cytokine release. The poster ends with a list of factors that raise PTH.
Post states vitamin E prevents calcium oxalate kidney stones by lowering lipid peroxidation. It supports this with a quoted excerpt (PMID 15963133) on hyperoxaluria-induced peroxidation and vitamin E treatment. The quoted post (lowmegatron) says coffee lowers kidney stone risk by about 10% per 8 oz.
The author says nutrition matters even when taking thyroid hormone. The quoted account (_palmerprescott) describes T3 having no effect for over a year until about a week of zinc supplementation.
Author recommends eggshell powder as a calcium source for people who cannot tolerate dairy. They cite a quoted abstract (PMID 15018022) on bone and cartilage effects and give a step-by-step guide for making it at home.
Post is a Ray Peat quotation giving a historical account of vitamin E research. Peat says vitamin E's anti-estrogenic action was reframed as an antioxidant effect, which fed the free-radical theory of aging. He also says polyunsaturated fats cause lipofuscin formation and degeneration.
lowmegatron says Shute's work used natural vitamin E from wheat germ oil and was later 'debunked' with synthetic dl-alpha tocopherol, which is not found in nature. The author names TocoVit by IdeaLabs as the closest match they know of. The author also says the screenshots come from comments on their Facebook page and were reposted with permission.
The author cites a paper suggesting that stress-related high histamine combined with vitamin C depletion damages arterial endothelium and predisposes to atherosclerosis and myocardial infarction. The author lists agents said to help lower histamine, depending on context, and common causes of elevated histamine.
The author links low thyroid hormone status to liver fibrosis and NAFLD/NASH. They cite human association studies, mouse experiments on T3 and fibrosis, and a resmetirom trial. They say above-range thyroid hormone is also associated with fibrosis and that the goal is an optimal range. The embedded quoted post from lowmegatron claims cirrhosis impairs T3 production.
The author reports another failed thyroid blood test with a different company and says they will hold off sending any until the New Year. The quoted post from lowmegatron describes starting use of a device near the thyroid, with 2 minutes per side at 1.5 inches and a plan to increase to 8 minutes per side every other day.
Quoting Ray Peat, the post says physiological T3 reversed heart fibrosis in rats, and that heart enlargement is traditionally blamed on thyroid hormone at very high doses. The author adds that T3 is needed to minimize fibrosis and cites a post-MI T3 infusion study reporting reduced scar size and preserved function.
The author says vitamin K2 is essential for cardiovascular health and reduces calcium and plaque buildup, citing rabbit and rat studies with pharmacological doses of K2/MK-4. The embedded lowmegatron post quotes Ray Peat and human and animal studies on vitamin K2 for bone and arterial calcification.
lowmegatron announces a new interview with Dr Wilson and links to it. The post does not describe the interview's content; the root post concerns Wilson's T3 Protocol.
The author says glycine can protect the liver from alcohol-induced injury by reducing lipid peroxidation and the inflammatory response to bacterial endotoxins. They add that gelatin/collagen/gelatinous foods are generally better than glycine powder, and quote two abstracts (animal/mouse models).
The author argues that seed oils (linoleic acid) amplify alcoholic liver damage while saturated fats are protective. Support cited is a rat study, a 60-day randomized trial in severe alcoholic hepatitis comparing ghee with soybean oil, and a quoted Ray Peat excerpt.
The author describes a rat study in which glycine-rich diet sped recovery from alcohol-induced liver injury after alcohol was withdrawn, with faster declines in liver enzymes, damage scores, and liver fat, and less inflammation signaling.
The author posts a Christmas greeting with no health content.
The post contains only a shortened t.co link and attached media, with no explanatory text. Its content cannot be determined from the retrieved text.
The post contains only a bare link. Its subject cannot be determined from the supplied text.
A quoted passage says basal metabolism correlates fairly closely with IQ within normal and slightly above-normal limits. It links this to clinical pictures of slow, underactive low-metabolism types and overactive high-metabolic-rate personalities.
The author describes a small study of 20 healthy women in which black coffee was followed 1 hour later by significantly lower blood sugar and cortisol. The author explains this via cortisol's effect on glucose and coffee compounds that reduce cortisol reactivation. The quoted post links coffee, 11β-HSD1, cortisol and depression.
The author presents a case report and commentary from a paper saying thyroid supplementation (natural desiccated thyroid) lowered a hypothyroid patient's raised blood pressure after thyroidectomy. The paper reports that only about 20% of hypertensives normalize, 55% partly improve and 25% do not respond. The quoted post warns that a doctor's presence can raise blood pressure readings.
The author says T4/levothyroxine is not thyroid hormone and that high doses of T4 alone can reduce tissue T3 even if labs look fine, supported by a Ray Peat quote. The quoted post is an anecdotal Facebook testimonial reporting many improvements after switching to T3.
The post shares Ray Peat's first-person account of reactions to synthetic vitamin C (relief from poison oak, then sore throats, bronchitis and sickness from manufactured ascorbic acid), contrasted with no symptoms from fruit juice. The quoted post summarizes a small proof-of-concept study in which vitamin C lowered TSH and improved symptoms in people on levothyroxine.
The author claims ginger reduces lipogenesis, fat mass and waist circumference and shifts metabolism toward fuel burning, and that it improves thyroid markers and lowers serotonin. The post supports this with excerpts from two meta-analysis/clinical papers and one rodent study, plus a quoted post from lowmegatron making similar claims about ginger and fat cells.
The author announces a 500 Watt halogen work light as a 'big gun unlocked'. No health claims are stated in the retrieved text.
The post shares a quote attributed to Napoleon Bonaparte about strong coffee waking him and giving warmth, force and a painful pleasure. No further health explanation is given.
The author claims hypothyroidism raises noradrenaline, which can increase blood pressure, cholesterol and anxiety. The post quotes Menoff's paper and studies it cites (Christensen, Stoffer) on thyroid hormone and catecholamines. The embedded lowmegatron post presents a case report and paper commentary on thyroid hormone (NDT) lowering blood pressure in some hypothyroid patients.
The post shares Ray Peat interview excerpts claiming cooked potato juice or soup can relieve insomnia and help people who cannot digest protein. It presents ketoacid equivalents in potato protein as absorbing ammonia. The author adds that ammonia buildup is neurotoxic and causes insomnia, which is why Peat suggested potato juice.
The author says blood sugar tends to be elevated in human anaphylaxis, and that it is unclear whether this is protective, causal or incidental. They quote rat and mouse experiments in which low blood glucose worsened anaphylactic or anaphylactoid responses and high glucose delayed or reduced them. They note epinephrine, used in anaphylaxis, causes hyperglycemia.
The author claims copper dissolves in human sweat and may be absorbed from copper jewelry. They claim copper optimization benefits immunity, energy, thyroid and cardiovascular health. They quote a study on sweat copper solubility and weight loss of copper bracelets, and a Ray Peat quote on iron and copper interaction.
The author claims potassium deficiency reduced sugar metabolized by 27% and decreased the insulin response to high blood sugar. They list potassium food sources and state that few US adults meet the 4.7 g/day intake. They quote a study abstract on experimentally induced potassium depletion and glucose intolerance.
The author explains the Broda Barnes basal temperature test as a proxy for basal metabolic rate and thyroid hormone (T3) activity. They describe how to measure it and cite the normal values. They list factors that can make it unreliable, including birth control pills, HRT and menstrual cycle timing. The embedded post by lowmegatron describes a myxedema coma case report with subclinical hypothyroidism.
Post quotes Ray Peat saying optimal thyroid function and a good dose of vitamin B1 can greatly increase learning power. He recounts giving poorly nourished evening English students high-protein cookies with B1 and a pre-class cookie-and-coffee snack, after which they became good students.
The author says they receive daily questions about whether one is hypothyroid when tests may be unreliable, which supplement to take and how much thyroid hormone is needed. They say these are reasonable questions without simple answers and link to an explanation.
lowmegatron says 'hypothyroidism' is used for several different conditions that lead to low thyroid hormone activity. True hypothyroidism is when the thyroid gland cannot produce enough hormone, and there are multiple reasons for that.
lowmegatron defines primary hypothyroidism as a problem in the thyroid gland itself. Secondary is pituitary failure to stimulate the thyroid, and tertiary is hypothalamic failure to stimulate the pituitary.
lowmegatron says Hashimoto's is the main cause of primary hypothyroidism and that handling it differs from secondary or tertiary cases. The author says TSH and T4 are the most common tests and are good at flagging severe primary hypothyroidism. However, TSH is often low or normal in secondary and tertiary cases, and neither test shows T3, which the author calls the critical component.
lowmegatron claims hypothyroid symptoms mostly come from low thyroid hormone activity inside cells. T3 is the active hormone, but the gland releases mostly T4, which must be converted. The author also says rising TSH in primary hypothyroidism is inflammatory and affects other organs, notably the heart.
lowmegatron says low thyroid hormone activity can cause hypothyroid-like symptoms even when the thyroid produces enough hormone. The author says this is not true hypothyroidism and is not recognized as such medically, because the thyroid, pituitary and hypothalamus are working, but the symptoms are similar because of low T3 activity.
lowmegatron says decreased T4-to-T3 conversion can cause hypothyroid symptoms in someone who would not be diagnosed as hypothyroid. The author states there are many possible reasons for poor conversion and the cause must be identified to fix it.
lowmegatron says TSH and T4 are often normal in people with conversion issues. Such people may be told their thyroid is fine, though the author says they may still have a thyroid hormone issue causing symptoms.
lowmegatron claims conversion issues are often dismissed, leaving people on 'horror drugs' for misdiagnosed symptoms. The author says a T3 test may detect a conversion issue that TSH or T4 misses, and that the ratio of reverse T3 to T3 or T4 is often more telling. Reverse T3 is described as made from T4, wasting potential T3.
lowmegatron says even T3 blood tests are imperfect because they sample only a small pool of hormone. The author says hormone converted and used inside the same cell never appears in blood, and that transport into tissues can be impaired, so even optimal blood results are not 100% reliable.
lowmegatron says body temperature is a useful indicator of overall thyroid hormone activity. The author describes Broda Barnes's Basal Temperature Test, a home test taking an armpit reading for ten minutes on waking. Barnes is said to have argued that hypothyroidism is vastly underdiagnosed.
lowmegatron states that readings of 97.8 °F (36.6 °C) or below indicate hypothyroidism and readings over 98.2 °F (36.8 °C) suggest hyperthyroidism. The author adds that other factors affect body temperature and the basal test, though less variable than other readings, is not perfect.
lowmegatron says women's basal temperature varies across the menstrual cycle, peaking just before menstruation and lowest at ovulation. He therefore recommends recording it on the second and third days after menstruation begins during menstrual years. Before menarche or after menopause, he says it can be taken any day.
lowmegatron claims birth control pills and HRT override natural hormonal fluctuations. He argues that Barnes's basal-temperature test therefore cannot reliably reflect thyroid status in pill or HRT users, because the early-follicular temperature trough is abolished or replaced by an elevated or erratic baseline.
lowmegatron says levothyroxine is the most common treatment for true hypothyroidism and is T4, which must be converted to T3. He claims conversion is rarely optimal on levothyroxine alone and that adding some T3 "kickstarts" conversion and gives a more stable T3 supply through the day.
lowmegatron claims TSH responds well to levothyroxine/T4 but is over-suppressed relative to the thyroid hormone available to cells, so low TSH does not mean adequate thyroid hormone. He says the amount and T4:T3 ratio needed vary hugely between people and compares this to insulin dosing in type 1 diabetes.
lowmegatron says diet and lifestyle determine thyroid gland health, hormone conversion, uptake and activity in cells. He claims stress and nutritional deficiencies can rapidly cause low thyroid hormone activity with normal TSH and T4. He cites a woman he spoke with who improved after dietary changes and swapping some workouts for walks.
lowmegatron claims that even large doses of active T3 may not work if nutrition is inappropriate. The post includes an image, whose content is not described in the text.
lowmegatron argues that questions about hypothyroidism lack one-size-fits-all answers and that anyone offering broad solutions doesn't understand the problem. He promotes his Hypothyroid Masterclass Course, described as 31 short video modules, and lists the topics covered (tests, conversion, reverse T3, T4/NDT/T3 supplementation, nutrients, PUFA, stress, diet, drugs).
Post quotes Ray Peat saying good exercise is anything that raises body temperature through muscle heat production, such as resistance exercise, walking or short bursts of running. He contrasts this with prolonged breathless exercise that causes hypocapnia, and says good exercise increases carbon dioxide and decreases inflammatory lactic acid.
The author states that people burn fewer calories daily than decades ago, mostly because of lower resting energy use, quoting a paper excerpt that rising obesity was probably not driven by reduced physical activity and that adjusted basal metabolic rate has declined. A quoted post from lowmegatron says thyroid blood tests can be normal despite low-thyroid symptoms because TSH/T4 and even T3 tests are limited.
Post quotes Ray Peat saying progesterone raises body temperature while estrogen lowers it via nitric oxide and vasodilation, and that hot flashes reflect estrogen imbalance relative to progesterone. It adds an excerpt from a paper on menstrual-cycle temperature regulation. An embedded lowmegatron post quotes Peat saying a few progesterone doses can shift balance and aid T4-to-T3 conversion.
Author claims cell phone radiation increases subsequent food intake, citing a crossover study in 15 young men where 25 min of RF-EMF exposure raised caloric intake by 22–27%, mostly from carbohydrate, with altered brain energy metabolism on scans. The embedded quoted post (lowmegatron) claims heavy phone use is associated with higher TSH and lower thyroid hormones, and recommends distance or hands-free use.
The post quotes Ray Peat saying that higher coffee intake, up to five or more cups, is linked to lower liver disease and dementia risk, which he attributes to support of thyroid function, lower nitric oxide and protection of mitochondria. The embedded post (lowmegatron) claims that two more cups per day is associated with 38–48% lower cirrhosis risk or death, and lists proposed mechanisms.
Author argues that people with anorexia have low T3 that improves with weight gain, that TSH is unreliable under stress, and that caloric restriction, fasting and exercise may suppress T3 and metabolic rate. Author suggests chronic repeated fasting likely harms long-term thyroid status. The embedded post (lowmegatron) says stress also lowers TSH, making it an unreliable marker.
The post quotes Ray Peat's anecdotes that progesterone or pregnenolone revived old horses and dogs. The author adds that these hormones lower CRH/ACTH, that excess cortisol accelerates aging, and that photos show a dog treated for Cushing's syndrome. The embedded post (lowmegatron) discusses thyroid hormone, lactate and CO2, and rodent data on transcutaneous CO2 against human tumor xenografts.
Author claims fasting and caloric restriction lower metabolism and thyroid hormone set points, often needing T3 to reset the famine response. A long quote from a paper on TSH and weight-loss hypothyroidism says TSH suppression during thyroid hormone treatment is expected. The embedded post (lowmegatron) claims carbohydrate deprivation cut T3 by 25%.
Author presents excerpts from a rat study reporting that hypothyroid rats gained more fat and converted less dietary protein into body protein while eating fewer calories. The author adds that T3 appears important for energy and lipid balance, and that hyperthyroid rats balanced higher energy expenditure with higher intake.

The embedded lowmegatron post adds Ray Peat's claim that hypothyroid people get poor deep sleep, plus a 1967 study of hypothyroid sleep EEG.
The author argues that thyroid hormone is essential for heart function and that supplemental T3 is sometimes needed. Two case reports are quoted, one of a child with myxedema heart disease and one of an adult with myxedema cardiogenic shock who improved on liothyronine. The embedded lowmegatron post quotes Ray Peat and studies on T3 and cardiac fibrosis after heart attack.
Ray Peat is quoted saying a liver supported by carbohydrate and thyroid can detoxify circulating PUFA via glucuronidation and sulfation, and that nightly PUFA release harms the brain. The author adds lists of nutrients and foods said to support sulfation and glucuronidation. The author also links PUFA peroxidation products to neurodegenerative disease via listed study titles.
New Year greeting with no health content.
The author argues that adequate calcium, especially from dairy, is linked to lower body weight, fat loss, less belly fat, lower metabolic syndrome risk and reduced fatty acid synthase. Quoted study excerpts are used as support. The embedded lowmegatron post recommends eggshell powder as a calcium source for people who cannot tolerate dairy and gives a preparation method.
Ray Peat is quoted saying titanium dioxide and silica particles put into animals' noses go to the brain and cause inflammation. He adds that ingested intestinal particles can reach the bloodstream and brain and cause inflammation.
Author shares a link with the comment 'Some holiday reading!'. The linked content is not in the retrieved text.
The author claims high-carbohydrate diets lower famine and stress signals and raise thyroid hormone conversion and metabolism, whereas low-carb acts as a famine signal that lowers conversion. Support is a Broda Barnes self-experiment quote saying high protein raises thyroid needs, and a quoted study (PMID 11167929) showing carbohydrate deprivation lowered T3 and raised reverse T3. An embedded MojitoSlammer post is a personal fat-loss anecdote crediting Ray Peat.
Author jokes that Ray Peat surely had a story about an octopus, calling them among the most interesting animals. There is no health content, and the linked or attached content is not in the retrieved text.
Author's own text is only the question "Is this the year?", posted over a quoted reply from another account saying "High carb will finish u". The post has no explanatory health content of its own.
Author's text is only a t.co link, posted over a quoted reply from GawdawgElite suggesting warm milk with a pinch of salt and 2 tablespoons of sugar, plus a little T3, before bed as "helpful". The post is context-dependent and the author adds no explanation or endorsement.
Author quotes a statement that thyroid dysfunction, particularly subclinical hypothyroidism, was found substantially among IBS patients. Author then lists that hypothyroidism slows transit time, increases serotonin and increases histamine. The quoted lowmegatron post argues hypothyroidism can cause SIBO and lactose intolerance, citing a Ray Peat quote and two PMIDs.
Author says T3 is critical for mood and motivation, that low T3 is often missed on basic thyroid labs (TSH, T4), and that basal temperature is the best single estimate, to be combined with labs. Author quotes a paper on hypothyroidism and depression, and the post embeds a lowmegatron post saying depression is a low-brain-energy state that can be caused by low thyroid hormone.
Author posts only "Potassium and histamine issues." with a t.co link and attached media whose contents are not available. No explanatory claim is visible in the retrieved text.
The author says thyroid hormone T3 is especially important for heart health, and that hypothyroidism or impaired T4-to-T3 conversion can lead to atherosclerosis, heart failure and heart attacks and limit recovery from them. The post quotes a paper on low T3 syndrome in myocardial infarction and heart failure. The embedded quoted post from lowmegatron describes a case report of a 16-year-old with hypothyroidism-induced dilated cardiomyopathy who improved on combined levothyroxine and T3.
The post text is only a link with no commentary from the author. The embedded quoted post by BrandonLuuMD claims female athletes have higher ACL rupture rates than males, and that peak estradiol around ovulation is associated with increased knee laxity and a possible temporary window of higher injury risk.
The author describes selenium as required for thyroid hormone conversion and as protective of the thyroid. They say deficiency may cause hypothyroid-like symptoms and that supplementation may lower thyroid antibodies in autoimmune thyroid disease, help Graves' eye disease, and speed recovery of thyroid hormones in acute stress. They also list selenium-rich foods and note an upper limit of 400 mcg/day.
The post text is only a link with no commentary from the author. The embedded quoted post by JThiel asks why carnivore dieters supposedly heal many health problems and become robust while high-carb vegans develop nutrient deficiencies. It also says the most robust humans in the anthropological record ate a low-carb carnivorous diet.
The author asserts that low thyroid hormone decreases immunity and that thyroid hormone needs may increase in winter. The post supports this with quoted statements from Broda Barnes about thyroid therapy, fewer infections and thyroidectomized rabbits, and a Ray Peat statement that people on thyroid supplements often need four times as much in December as in July.
The author argues that vitamin A deficiency disrupts thyroid function (higher TSH, goiter, reduced iodine uptake and hormone synthesis/conversion). Support is quoted review and trial excerpts and two PMIDs. The embedded quoted post from Metabolicmonstr gives an anecdote of a low vitamin A diet followed by worse eyesight and TSH rising from 1 to 21.
A Ray Peat quotation states that salty snacks help bring on sleep, probably by stabilizing blood glucose and lowering adrenalin. It adds that ice cream (sugar, calcium, fat) is often effective for improving sleep quality.
The author claims dark chocolate protects the gut barrier under stress and limits bacterial endotoxin (LPS) entering the blood. The post quotes a randomized controlled study in elite football athletes reporting decreased intestinal permeability after 30 days of dark chocolate, plus in-vitro Caco-2 results.
The author advises more dairy and less meat and grain for bone health. The supporting material is a Ray Peat quotation that excess phosphate removes calcium and magnesium from bones and teeth, and a quoted cross-sectional study linking low dietary calcium:phosphorus ratios to higher PTH and urinary calcium. An embedded post from lowmegatron says dysregulated calcium can calcify arteries and soft tissues.
The author claims estrogen increases cocaine use and progesterone decreases it. The support is a quoted review abstract (rat literature) on 17β-estradiol, progesterone and allopregnanolone in cocaine-related behaviours. A Ray Peat quotation also describes estrogen as excitatory, progesterone as calming, and T3 and progesterone as mutually reinforcing.
The author argues that levothyroxine (T4) alone does not fully correct slow metabolism or weight gain in hypothyroidism, because T3 drives metabolism. They say high-dose T4 may reduce T3 conversion and release, and that lowering TSH does not necessarily raise T3. They propose improving conversion or adding T3, and say basal body temperature is a better guide than TSH. The archived quoted post from lowmegatron links core temperature to fat gain and describes Broda Barnes's basal temperature test.
The post quotes Ray Peat's list of carbohydrates he considers good: citrus and grape juices, well-cooked root vegetables and cabbage-family vegetables, and non-gluten grains such as polished white rice and nixtamalized corn. The embedded lowmegatron post cites a study in which carbohydrate deprivation (2%) lowered T3 and raised reverse T3 and free T4 without changing TSH.
The post contains only a shortened link with no other text. Its content cannot be determined from the supplied text.
The post quotes a study finding that participants drinking at least four cups of coffee per day had a 63% lower depression risk than those drinking less than one cup per day. The embedded lowmegatron post quotes Ray Peat saying higher coffee intake (five or more cups) is associated with lower liver disease and dementia risk and that coffee supports thyroid function and mitochondrial protection.
The post answers why people seem sicker in winter with a Ray Peat quotation. Peat attributes winter sickness mainly to 'light deficiency' from long nights and little sunlight. He says prolonged darkness raises nocturnal stress and mitochondrial damage, and that orange and red light improve energy production. The embedded lowmegatron post shows a 500 W halogen work light.
The author says that warm-blooded animals spend substantial energy maintaining body temperature, that T3 plays the largest role in this, and that when basal temperature or T3 drops, calories are stored as fat instead. They support this with quoted passages from a paper on core temperature and obesity. The embedded quoted post is the lowmegatron levothyroxine/T3 post.
The posting account says corn oil plus bacterial endotoxin killed rats and caused liver injury and leaky gut in a cited rat study, and that MCTs prevented these effects. It calls coconut oil the best MCT source, adds that supplemental MCT seems inflammatory for many people, and quotes Ray Peat on unstable fats, endotoxin and lipid peroxidation. An embedded post by lowmegatron claims dark chocolate protects gut barrier function.
The post quotes Ray Peat arguing that a pathologically high TSH is treated as normal, that TSH acts on many non-thyroid cell types and may contribute to edema, fibrosis and cancers, and that no evidence shows very low TSH is harmful. An embedded lowmegatron post claims vitamin A deficiency raises TSH and impairs thyroid function.
The post quotes DrPaulMason's claim that applying plain Vaseline to the eyelids at night could be a safe, cheap and effective way to reduce Demodex mites. The embedded post says these mites likely fuel rosacea, acne, dry eyes and chronic nasal congestion, and suggests a 28-day Vaseline trial.
The posting account says an 11-day controlled experiment found that a very-low-carb (2%) diet raised urinary nitrogen excretion by 45% versus an 85% carb diet at equal calories and protein, and lowered T3. It interprets this as strongly suggesting lean tissue loss. An embedded lowmegatron post reports T3 falling about 25% on carbohydrate deprivation with reverse T3 rising and TSH unchanged.
The post quotes Ray Peat linking lower parathyroid hormone (via calcium and vitamin D) to reduced obesity and related problems. It adds quoted PMID excerpts associating depression with low vitamin D and high PTH and describing neuropsychiatric symptoms in primary hyperparathyroidism. It lists factors that can raise PTH. An embedded lowmegatron post links PTH and prolactin to men's libido and fertility.
The post contains only a shortened link with no other text. Its content cannot be determined from the supplied text.
The author lists health outcomes that citrus fruits are said to be 'shown to' produce, including effects on mood, inflammation, endotoxin, blood pressure, body composition, blood sugar, cognition and asthma. The embedded quoted post from lowmegatron asks Ray Peat about his 'good carbs' list and quotes his list of citrus juices, grape juice, cooked vegetables and non-gluten grains.
The author states that hypothyroidism, including subclinical hypothyroidism, raises cholesterol. They say levothyroxine lowers elevated cholesterol in subclinical patients, though less than levo+T3 or NDT. They quote a study excerpt reporting lower total and LDL cholesterol on L-thyroxine. They add that they are not claiming cholesterol itself is bad, but that elevated cholesterol is a good marker for hypothyroidism and other drivers of cardiovascular disease.
The author says Buteyko breathing can help with asthma, quoting a Buteyko Breathing Technique paper reporting reduced inhaled steroid and beta2-agonist use. They then give a long Ray Peat quotation linking thyroid function, CO2, lactic acid, adrenaline, endotoxin and nitric oxide to hyperventilation and asthma inflammation. The embedded quote, from lowmegatron, is another Ray Peat passage on protective CO2.
Answering a question about histamine and mast cell issues, the post gives Ray Peat's view that estrogen is the main promoter of mast cell and histamine overproduction. Peat also suggests that local anesthetics and ointments applied to itchy spots may stabilize mast cells. The author adds excerpts from three cited papers on estradiol, mast cell activation, allergy and endometriosis, including a rat study.
The author lists common causes of elevated histamine (such as high estrogen, endotoxin, hypothyroidism and nutrient deficiencies) and conditions in which histamine is implicated. They list things that 'can help', including vitamin E, progesterone, lidocaine, magnesium, l-theanine, thiamine, DAO and vitamin C. The embedded quoted post from lowmegatron opens a thread on 'histamine hacks' and lists the same implicated conditions.
The author quotes Ray Peat saying very bright incandescent light restores mitochondrial enzymes governed by thyroid hormone. Peat also claims lack of bright light causes progesterone deficiency, leaving estrogen and prolactin unopposed. The quoted context is the author's own post about a 500-watt halogen work light.

High cortisol causally increases risk of obesity, insulin resistance, type 2 diabetes, insomnia, depression, fatty liver, low T3 thyroid hormone, and high blood pressure. Post introduces tips for cortisol control in thread format.
lowmegatron claims vitamin C lowers stress-induced cortisol release, quoting studies on ascorbic acid inhibiting cortisol secretion after ACTH and on vitamin C in women with functional hypercortisolemia or elevated DHEA-S. He says he prefers vitamin C from foods such as fruit, juice and acerola powder.
lowmegatron claims parathyroid hormone increases cortisol and that PTH is elevated with low dietary calcium and low vitamin D status. He quotes in vitro and treatment studies reporting PTH stimulating cortisol secretion or raising tissue cortisol.
lowmegatron claims vitamin D appears to lower 11β-HSD1, a cortisol-regenerating enzyme implicated in insulin resistance, obesity, fatty liver and type 2 diabetes. He cites a study where 2,000 IU for 2 weeks reduced cortisol and the cortisol:cortisone ratio versus no change on placebo.
lowmegatron claims salicylate, an aspirin metabolite, lowers tissue cortisol regeneration by reducing 11β-HSD1. He quotes research on salsalate/salicylate improving glucose tolerance and reducing adipose 11β-HSD1 in mice and men.
lowmegatron claims aspirin itself lowers stress-induced increases in ACTH and cortisol, quoting a study saying aspirin blunted ACTH and cortisol and was associated with reduced cortisol after exercise.
lowmegatron says drugs that reduce local cortisol via 11β-HSD1 inhibition are being investigated for type 2 diabetes. He quotes a study reporting increased whole-body 11β-HSD1 activity in obese men with T2D, supporting the idea that inhibitors would be most effective in that group.
lowmegatron says coffee, linked to lower type 2 diabetes risk, contains 11β-HSD1 inhibitors that reduce local cortisol regeneration. The post quotes a study (PMID 16814782) reporting that espresso extract inhibited 11β-HSD1 activity and suggesting this may explain part of coffee's anti-diabetic effect.
lowmegatron says DHEA may also lower 11β-HSD1 and local cortisol generation. The post quotes a study (PMID 15613680) on DHEA, blood glucose and insulin sensitivity in obese rodents and humans. The author adds an opinion that low doses (no more than 5 mg, 3 times a day) are probably best because DHEA can otherwise increase estrogen.
lowmegatron says emodin, found in cascara sagrada, aloe and rhubarb, inhibits 11β-HSD1 and lowers local cortisol. In obese mice it reportedly reduced insulin resistance, liver fat and high blood sugar. The author mentions a supplement called Lapodin, which they say they have not tried and are not affiliated with.
lowmegatron says magnesium and potassium (250 mg each) lowered serum cortisol by nearly 50% in people with type 2 diabetes and improved insomnia scores. The post gives figures such as no-insomnia participants rising from about 5% to over 40% and severe insomnia falling from 38% to 0%.
lowmegatron claims darkness and low light keep cortisol elevated while bright light lowers it after an initial spike. The author says daytime bright light is important and that most indoor lighting is insufficient. The quoted study reported lower cortisol under constant bright light than dim light, but not under intermittent bright light.
lowmegatron claims creatine reduces stress-induced increases in cortisol. The quoted study says more than 5 days of creatine combined with resistance exercise was sufficient to increase testosterone and decrease cortisol concentrations.
lowmegatron says L-theanine lowers the cortisol response to stress. The quoted study was a double-blind, placebo-controlled crossover in which subjective stress fell at one hour and cortisol response at three hours. The active treatment was a combination of L-theanine, alpha GPC, phosphatidylserine and chamomile, not theanine alone.
lowmegatron claims hypothyroidism increases cortisol, that many hypothyroid symptoms resemble excess cortisol, and that TSH above 2.0 (or 2.5) is associated with higher cortisol. The author says thyroid hormone T3 regulates 11β-HSD2, which inactivates cortisol, so low thyroid hormone reduces cortisol detox, and that TSH is not a reliable way to assess this.
lowmegatron says hypothyroidism activates the sympathetic nervous system, raising stress hormones, anxiety, blood sugar and blood pressure. The author cites a study of hypothyroid people who stopped medication, reporting about +60% cortisol and doubled adrenaline, noradrenaline and aldosterone, with diastolic blood pressure dropping as T3 rose with replacement.
Obesity, especially central obesity, is linked to endocrine abnormalities including thyroid dysfunction. T3 regulates energy metabolism and thermogenesis; both subclinical and overt hypothyroidism correlate with weight gain and reduced metabolic rate. Study of 27,097 individuals shows hypothyroidism linked to higher BMI and obesity prevalence.
Low sodium diets increase plasma epinephrine and norepinephrine levels significantly compared to high-salt intake.
Estrogen-induced thyroid dysfunction is compensated by elevated adrenaline and cortisol, with inadequate compensation causing hypoglycemia and elevated histamine. Women with hypothyroidism on thyroxine may need increased dosing during estrogen therapy.
Long-distance running may be linked to higher rates of precancerous colon lesions through inflammation, stress hormone elevation, free fatty acid release, and increased gut permeability with endotoxin translocation.
Daily carrot consumption may produce hormonal shifts similar to antibiotic therapy: lowering cortisol and estrogen while raising progesterone, through bacterial modulation of liver detoxification in low-thyroid individuals with sluggish digestion.
lowmegatron quotes Ray Peat saying that in women and rats antibiotics lowered estrogen and cortisol and raised progesterone. Peat attributes this to the liver's improved ability to inactivate estrogen and maintain blood sugar when endotoxin stress fell, and suggests diets that reduce intestinal toxin production.
lowmegatron quotes a paper by A. Toth reporting six case histories in which long-term antibiotic therapy corrected luteal phase defect and relieved premenstrual symptoms.

lowmegatron quotes a study reporting that ethanolic extracts of peeled and shredded carrots had antimicrobial effects against food-borne micro-organisms and that fresh carrots had sufficient activity to inhibit spoilage bacteria.
lowmegatron quotes a study (PMID 474479) stating that 200 g of raw carrot daily for 3 weeks reduced serum cholesterol by 11%, raised fecal bile acid and fat excretion by 50%, and increased stool weight by 25%. The quote says the changes persisted 3 weeks after stopping and suggests altered bacterial flora or metabolism.
lowmegatron quotes a paper (PMID 30212943) saying carrot is widely eaten and may help prevent cancer. The quote cites meta-analyses showing reduced prostate and gastric cancer risk with high carrot intake, and says the literature links dietary carrot intake to decreased breast cancer risk.
Estrogen increases pain through serotonin-dependent pathways. Chronic pain perpetuates itself via serotonin signaling that hyperactivates TRPV1 receptors in the trigeminal nerve, amplifying nociceptive responses. Estrogen, serotonin, and inadequate postpartum cholesterol confluence promotes inflammation and pain.
The cortisol-regenerating enzyme 11β-HSD1 increases local cortisol in liver and adipose tissue without detectable blood elevation and is implicated in insulin resistance, obesity, and fatty liver. Coffee and vitamin D (2,000 IU) inhibit 11β-HSD1 activity and reduce cortisol burden.
During inflammation and stress, adrenal glands secrete adrenaline and cortisol to raise blood sugar in response to inflammation or stress signals (blood sugar, lactic acid, or CO2 changes), assuming the glands are not exhausted or starved.
Stress-induced cortisol elevation suppresses TSH and impairs thyroid hormone T4-to-T3 conversion while elevating reverse T3, resulting in low functional thyroid hormone despite normal TSH and T4 labs. Free fatty acids further impair T3 metabolism.
Four infertile patients conceived within months after completing long-term antibiotic therapy, consistent with antibiotic correction of luteal phase defects and hormonal dysregulation.
Author reports personal thyroid experiment results comparing their Graves' hyperthyroidism case to the quoted protocol for Hashimoto's; finds FT3 improved 15-20% but antibodies continued rising on previous trend, questioning efficacy in their condition.
DHEA improves insulin sensitivity and reduces abdominal fat through decreased local cortisol production via 11β-HSD1 inhibition; coffee, vitamin D, and aspirin share this mechanism.
lowmegatron quotes a randomized trial in which elderly women and men took 50 mg/day DHEA or placebo for 6 months. The quote says DHEA reduced abdominal fat and improved the insulin sensitivity index.
lowmegatron quotes a paper reporting that in 3T3-L1 adipocytes DHEA downregulated 11β-HSD1 and reduced its oxoreductase activity, comparably to rosiglitazone but not additively. The authors propose that some of DHEA's anti-diabetic effects may come from inhibiting local glucocorticoid amplification in adipose tissue.
lowmegatron quotes a paper stating that 50 mg DHEA replacement improved glucose tolerance in participants who initially had abnormal glucose tolerance.
lowmegatron quotes a rat study in which animals fed a high-fat diet plus 0.3% DHEA were largely protected against increased visceral fat. The quote concludes DHEA protects against visceral fat accumulation and muscle insulin resistance in these rats.
lowmegatron states that high doses of DHEA can be estrogenic. He says he thinks 5 mg or less up to 3 times daily topically is safer and points to old Haidut discussions on the raypeatforum for details.
The author claims low thyroid hormone can lower androgens, neurosteroids and other steroids derived from pregnenolone, such as DHT, DHEA, testosterone, progesterone and allopregnanolone. He says T3 regulates StAR, which shuttles cholesterol into mitochondria. The quoted context claims hypothyroidism can cause low testosterone with raised prolactin.
Hypothyroidism causes atherosclerosis; elevated TSH increases MCP-1 expression which drives atherosclerosis via monocyte recruitment; thyroid hormone replacement (L-T4) improves atherosclerosis markers like CIMT.
Depression as hypothyroidism symptom stems from low brain energy; T3 augmentation of SSRIs corrects brain bioenergetic dysfunction in ~40% of treatment responders; TSH testing cannot detect tissue-level hypothyroidism.
Magnesium deficiency impairs thyroid function via decreased hormone conversion, thyroid enlargement, and reduced iodide uptake; low serum magnesium predicts Hashimoto's antibodies and hypothyroidism; Ray Peat explanation of magnesium's role in energy metabolism and thyroid hormone function.
lowmegatron's post contains only a link. The content is not visible in the supplied text, so no substantive claim can be extracted. The root post is about magnesium deficiency and thyroid function, but the link's content is unknown.

Thyroid hormone T3 and its metabolite TRIAC reverse learned helplessness in animal models by correcting energy metabolism rather than as a purely psychological intervention; low brain T3 increases serotonin which may contribute to learned helplessness.
Caloric restriction lowers T3 via decreased T4-to-T3 conversion (not thyroid output); T4 is shunted to reverse T3 instead; TSH suppression during treatment reflects normal adaptation, not overmedication; standard thyroid testing fails to detect this metabolic suppression.
Histamine produced by gut bacteria causes IBS pain; reducing fermentable carbohydrates decreases histamine and pain; germ-free mice colonized with high-histamine IBS microbiota developed visceral hyperalgesia reversible by low-fermentable diet or H4 receptor blockade; Ray Peat recommends easily-digested foods and antiseptic options; antihistamine cyproheptadine effective for IBS abdominal pain.
Gut serotonin increases blood sugar and insulin resistance through lipolysis and hepatic gluconeogenesis; anti-serotonin agents like ginger may improve these conditions. Multiple cited studies on serotonin's role in glucose metabolism and antidepressant use association with diabetes risk.
Terminal cancer patients showed 4x greater one-year survival when thyroid was shut down via methimazole with T3 replacement versus standard care. 83% exceeded expected 20% one-year survival. Mechanism relates to low T4 association with improved survival in some tumors.

No commercial promotion included.
Exercise in caloric deficit lowers T3 thyroid hormone and causes amenorrhea; increasing calories can help. CICO model ignores thyroid hormone and metabolic rate adaptation. Cortisol from exercise and low-calorie stress lowers TSH, which doctors may miss. Study tested effects but not TSH.
Endotoxin/LPS (lipopolysaccharide) causes multiple neuropsychiatric effects: decreased empathy, anxiety, depression, fear, anhedonia, and social isolation.
lowmegatron says women injected with endotoxin showed less empathy for others' pain than those given placebo. He suggests low-grade inflammation may reduce empathy as an adaptive energy-conserving strategy.
lowmegatron states that endotoxin reduces the ability to experience pleasure in women, with a link or media attached.
Wearable device heart rate parameters can accurately predict thyroid function in hypothyroidism. Thyroid hormone activity strongly influences resting heart rate; Ray Peat suggests ~85 bpm indicates adequate T3. Resting heart rate trends better than one-off measures; morning measurement most reliable.
lowmegatron corrects a typo in his earlier post on dieting and thyroid hormones: the phrase 'because TSH increases during stress' should read 'TSH decreases'.
Cyproheptadine blocks mediators of stress from hormonal-nutritional deficiencies (Ray Peat). It inhibits acetylcholine and serotonin-induced CRF release, reducing ACTH in Cushing's disease patients. CRF initiates HPA axis stress response.
Ray Peat quote on innate immune competence for bacterial endotoxin in normal stress, but accumulated unstable polyunsaturated fats increase inflammatory stress from endotoxin exposure. High-PUFA diet increases endotoxin-bacteria; chronic endotoxin infusion in mice increased fasting glucose, insulin, and weight gain.
Decaffeinated coffee reduced cholesterol, liver enzymes (ALT), fatty liver, and weight gain in mice fed high-fat/high-PUFA diet. Coffee reduces intestinal permeability and endotoxin; also reduces 11β-HSD1 (cortisol-regenerating enzyme) implicated in insulin resistance, obesity, fatty liver, and type 2 diabetes.
11β-HSD1 inhibitors under investigation for type 2 diabetes treatment. Cortisol raises blood sugar and free fatty acids (necessary in healthy states but chronically elevated in dysregulation). Coffee, aspirin, and vitamin D reduce 11β-HSD1 activity and associated with reduced diabetes risk.
Ray Peat quote on hypothyroidism-related hormonal dysregulation (elevated adrenalin, estrogen, cortisol; low magnesium) and insomnia treatment with T3 and magnesium.

Embedded post by lowmegatron on histamine as cause of IBS pain; reducing fermentable fiber intake reduced pain and urinary histamine; histamine-lowering strategies via diet and H4 receptor blockade; Ray Peat dietary recommendations and antihistamine cyproheptadine for functional abdominal pain.
Calcium-to-phosphorus ratio importance for weight loss and metabolic health. Ray Peat quote on milk/cheese for weight loss. Studies show dietary calcium augments fat loss during caloric restriction and increases trunk fat loss; dairy products have substantially greater effect. High calcium reduces metabolic syndrome risk by 20%. Calcium inhibits fatty acid synthase in adipocytes. Embedded post by lowmegatron synthesizing calcium effects on weight, body composition, abdominal fat, and metabolic syndrome.
TSH and T4 levels predict resting metabolic rate, weight gain, and obesity.

Embedded comprehensive quote from lowmegatron covers thyroid hormone, fibrosis, NAFLD, animal studies, human drug trials (resmetirom), and fibrosis in other tissues.
Quotes a passage claiming that, per calorie, sugar is less fattening than starch because it stimulates less insulin and, with a good diet, increases thyroid hormone activity. It lists indicators of metabolic rate: daily temperature cycle, pulse rate, evaporative water loss and Achilles reflex relaxation speed.
Quotes a claim that reducing dietary polyunsaturated fats lowers tissue stores over about four years, making it easier to keep metabolic rate up and stress hormones down.
Ray Peat quoted on weight loss strategy: eat to increase metabolic rate rather than restrict calories; adequate protein supports muscle gain, which increases basal metabolic requirement. For fat loss, recommends low-fat milk, eggs, orange juice, and carrot (avoiding high-fat whole milk).
Repeats the quoted passage that sugar is less fattening than starch per calorie, citing lower insulin stimulation and increased thyroid hormone activity, and lists metabolic rate indicators such as temperature, pulse and Achilles reflex relaxation.
Repeats the quote that reducing dietary PUFA lowers stored PUFA over about four years, helping keep metabolic rate up and stress hormones down.
Quotes a claim that the calcium-to-phosphate ratio is important, so milk and cheese help weight loss or prevent gain, and low-fat versions suit less active people.
Quotes a claim that when metabolic rate rises and stress hormones fall, such as after adding two quarts of milk daily, muscle may increase while fat decreases, gradually raising caloric requirements.
Quotes an anecdotal claim that some people lost weight by eating a raw carrot daily, reducing endotoxin stress, and that the liver treats PUFA like toxins but high concentrations poison detoxification.
Quotes a claim that antiseptic fiber such as bamboo shoots or raw carrot aids weight loss by reducing endotoxin and stress hormones and letting the liver metabolize better.
Quotes claims that stored PUFA released by stress or hunger slows metabolism; niacinamide lowers free fatty acids; small amounts of coconut oil aid fat oxidation; aspirin reduces stress-related free fatty acid rises; thyroid supplements are reasonable until the saturated-to-PUFA ratio is about 2:1. Includes a personal anecdote of losing about two pounds weekly with a tablespoon of coconut oil.
Author argues that hypothyroidism and higher TSH, even within the normal range, are linked to insulin resistance and type 2 diabetes. They cite Broda Barnes' clinical observations, an animal study (PMID 37884783) on TSH-linked inflammatory pathways, and a human retrospective study (PMID 29342130) on TSH and HOMA-IR.
Quotes a study conclusion that hypothyroidism is tied to higher dementia and mortality risk and that adding T3 may mitigate this better than LT4 alone. The author adds that T4 must convert to T3, many cannot convert enough, and T4 suppresses TSH effectively, misleading those who rely on T4/TSH labs.
The author argues few studies dose T3 individually, so the benefit of proper treatment may exceed what the paper found, and says the goal should be correcting low metabolic rate rather than a fixed T3 dose. It cites two PMIDs. The quoted earlier post claims hypothyroidism nearly doubles dementia risk, worse with thyroid medication, and links lipid peroxidation to neurodegeneration.

lowmegatron claims that cortisol, glucagon and adrenaline inhibit thyroid hormone conversion, lowering T3 and raising reverse T3. He lists factors he says commonly raise cortisol and adrenaline, including poor sleep, too few carbohydrates, sodium, potassium, magnesium or calcium, fasting, chronic caloric restriction, noise, shallow breathing, black coffee on an empty stomach and constant stimulation. He suggests acerola vitamin C, L-theanine and glycine as possibly helpful.
lowmegatron advises getting sufficient iodine. He says deficiency can lower thyroid levels, high doses can cause hypothyroidism, hyperthyroidism or autoimmunity in susceptible people, the RDA is 150 mcg and intakes above 300 mcg daily may pose risks. He also says X-ray contrast media can trigger problems and that seafood and dairy are good sources.
lowmegatron claims that the thyroid adjusts to energy availability, so undereating or excessive exercise can lower thyroid hormone production and metabolic rate. He warns against combining fasting with intense exercise, recommends muscle-focused exercise, and suggests mild, careful caloric restriction balanced with adequate intake periods.
lowmegatron advises limiting goitrogens, which he says can interfere with thyroid hormone levels before a goiter is visible. He names cruciferous vegetables and soy as the main offenders, says cooking reduces them and says iodine insufficiency increases their effect.
lowmegatron claims that polyunsaturated fats from seed oils and from non-ruminants fed high-PUFA diets disrupt thyroid hormone production, transport and binding. He says they are released as free fatty acids during stress, recommends mostly saturated fats (coconut oil, cocoa butter, butter/ghee, cream, cheese, tallow) and lists many oils, including fish oil, to avoid.
lowmegatron advises minimizing exposure to plastics and plasticizers, claiming that phthalates and BPA/S/F impair thyroid gland function and peripheral hormone conversion and that BPA blocks thyroid hormone at the receptor. He lists sources such as fragranced cosmetics, plastic containers and bottles, can linings, dust and thermal receipts. The quoted earlier post cites a rat study (PMID 31757552) in which ginger protected against BPA-induced thyroid damage.

Thyroid hormone receptors present in nasal mucosa; hypothyroidism triggers edema, inflammation, and vascular proliferation.
Ray Peat explains levothyroxine monotherapy can worsen thyroid problems by suppressing residual thyroid T3 production. Symptoms result from low T3 availability, not TSH level. Desiccated thyroid products (Armour, Thyrolar, Euthroid, Proloid) containing both T4 and T3 at physiologic ratio more effective. Embedded post details levothyroxine alone fails to correct slow metabolism and weight gain; T3 drives metabolism. High-dose levothyroxine can reduce T3 conversion and suppress gland T3 release despite lowering TSH.
Ataxia (lack of muscle coordination, instability, clumsy movement) can be caused by hypothyroidism and is reversible with early thyroid hormone replacement. Case report of 40-year-old male with gait ataxia from primary hypothyroidism with anti-TPO antibody positivity, fully improved within 8 weeks of thyroxine.

Thyroid hormone resistance means tissue unresponsiveness despite high hormone levels due to defective thyroid hormone receptor beta.
Broda Barnes observed that hypothyroid patients experience recurrent infections and demonstrated in animal experiments that hypothyroidism directly weakens immunity. Resistance to thyroid hormone patients have 50% more ear, nose, throat infections than relatives without the condition; insufficient T3 is correctable.
Ray Peat quotation describes high metabolic rate in young people converting cholesterol into pregnenolone, DHEA, and progesterone to maintain low blood cholesterol; age-related decline in metabolic rate increases cholesterol as a regulatory process supporting synthesis of protective neurosteroids. Embedded post cites clinical evidence that thyroid is the only thing safely lowering cholesterol and that thyroid dysfunction impacts lipid profiles.
CO2 increases mitochondrial biogenesis, a process linked to energy production and resistance to aging. Low mitochondrial biogenesis is associated with neurodegenerative diseases, metabolic syndrome, cardiovascular disease, and other conditions. CO2 is absorbed through the skin and regulated by thyroid hormone T3. Transcutaneous CO2 may have therapeutic potential for muscle strength recovery and the elderly.
Broda Barnes, MD reported that women with menstrual disorders treated with NDT thyroid therapy experienced high rates of symptom relief. Basal metabolic rate or basal temperature testing better identifies thyroid deficiency than blood tests. NDT containing T3 is more effective than levothyroxine monotherapy, though synthetic T4 plus T3 combination works similarly.
Hypothyroid symptoms are primarily caused by low T3 activity in cells and tissues, not just low production by the thyroid gland. Current diagnostic testing with TSH and T4 cannot assess cellular T3 activity, so many people with low T3 activity remain symptomatic despite normal blood tests. Low T3 activity has multiple causes beyond thyroid gland failure.
Glycine at 3g before bed improves sleep quality and reduces daytime sleepiness and fatigue in sleep-restricted subjects. Performance on psychomotor vigilance testing also improved in those given glycine.

Aspirin is metabolized to salicylate, which interferes with vitamin-K-dependent coagulation factors. Vitamin K significantly reduces/prevents bruising and bleeding from aspirin use. Ray Peat recommended taking vitamin K with aspirin. Case report demonstrates vitamin K correction of salicylate-induced coagulopathy.
Repost sharing user experiences of T3 thyroid hormone therapy. Two people report multiple improvements including weight loss, temperature normalization, resolution of psoriasis, return of ovulation, reversal of PMDD and emotional symptoms, reversal of Raynaud's, cholesterol normalization, discontinuation of ADHD medication, and resolution of histamine-related symptoms. Study cited showing experimental hypothyroidism increases mast cells and histamine in rats.
Blood tests cannot detect thyroid hormone activity in tissues and cells, only blood levels. Many people remain symptomatically hypothyroid despite normal blood tests because thyroid hormone activity in tissues is low. Basal temperature, influenced primarily by T3, is often a better indicator of thyroid hormone activity than blood tests.
Rosacea may result from gastrointestinal issues.

Low T3 (active thyroid hormone) is linked to depression. T4 must convert to T3 to be effective. Poor T4-to-T3 conversion can leave brain thyroid activity low even with normal standard labs. TSH above 2.5 mU/L is associated with more depressive symptoms in T4-treated people. Standard tests focusing on TSH and T4 miss tissue-level thyroid activity; T3, reverse T3, and conversion capacity are more relevant.
Ray Peat quote on T3 concentration in brain: brain maintains 1:1 T3:T4 ratio and cannot use excess T4 effectively; adding T4 can displace active T3 and cause neurological symptoms (strange sensations, tinnitus, memory problems), indicating worse thyroid function.
lowmegatron argues that hypothyroid dogs have lower energy expenditure and that levothyroxine raised it. He cites a study in which 18 of 20 obese dogs lost weight, lethargy improved in 14 of 15, and 93% of dogs with skin or coat problems improved or resolved. He states that thyroid hormone accounts for about 50% of BMR and that dogs seem to respond better to levothyroxine than people do.
Higher coffee intake associated with lower liver fibrosis and cirrhosis risk: 4 cups/day linked to 84% lower odds of cirrhosis vs no coffee. In advanced fibrosis, 3+ cups/day associated with fewer serious liver events. Caffeine blocks A2A adenosine signaling in hepatic stellate cells, reducing collagen production. Coffee may also reduce lipid peroxidation, lower iron, enhance autophagy, suppress NF-κB inflammation, and improve gut barrier function.

Brief reference to seed oils in response to quoted post about diabetes genetics.
T3 thyroid hormone production drops in diabetes due to impaired peripheral conversion from T4; high free fatty acids and gluconeogenic hormones impair conversion; levothyroxine monotherapy may not resolve hypothyroid symptoms despite lowering TSH; high blood sugar indicates glucose utilization impairment not sugar causation.
Hypothyroidism slows gut motility and stomach acid secretion, causing constipation and delayed gastric emptying; this creates conditions for SIBO; speeding digestion via thyroid treatment reduces bacterial overgrowth risk.
Seizure-alerting dogs exhibit attention-getting behavior prior to seizure onset, likely via scent detection or other sensory cues; may cue on specific seizure types, aura presentations and patient behaviors; alerting effectiveness depends on human recognition and response.
Low T3 thyroid hormone, high histamine and high serotonin are implicated in learned helplessness behavior; T3 is anti-inflammatory and stabilizes mast cells to reduce histamine and serotonin secretion; same treatments that reduce learned helplessness also reduce inflammatory response and histamine.
Broda Barnes recommended minimum effective dosing of natural desiccated thyroid for symptom relief in adults, typically 2 grains, sometimes 3, rarely 4; synthetic T4 with small T3 doses is usually equally effective; basal temperature normalization is secondary to symptom resolution.
Under his post on slowed gut motility and SIBO, lowmegatron promotes his video course on hypothyroidism and what to do about it, with a link.

Potassium is essential for glucose tolerance, insulin secretion, stroke prevention, blood pressure, vascular calcification prevention, and weight loss. <2% of US adults meet ≥4700 mg/day recommendation. Six mechanisms supported: experimental potassium depletion impairs glucose and insulin; lower intake linked to higher stroke risk in men and women; low potassium associated with metabolic syndrome and vascular calcification; potassium supplementation lowers blood pressure. Food sources: oranges, grapes, milk, coconut water, potatoes.
Selenium deficiency causes thyroid hormone problems and insulin resistance. In type 2 diabetes patients with coronary heart disease, 200 mcg selenium for 8 weeks improved insulin sensitivity and reduced inflammation (decreased insulin, HOMA-IR, hs-CRP; increased QUICKI, TAC). In hypothyroid patients on thyroid hormone, HOMA-IR decreased and insulin sensitivity improved. Author recommends checking intake via Cronometer before supplementing, as excess selenium is harmful.

Light therapy improves anxiety, depression, fatigue, pain, and sleep problems in Hashimoto's hypothyroidism patients within 3 weeks, despite levothyroxine monotherapy at TSH-lowering doses.
lowmegatron describes a study in which patients with Hashimoto's disease were randomized into two groups of 33. Both were "treated" with a laser device, but in the sham group only the display was on and the laser was not.
lowmegatron gives study details: two sessions per week for 3 weeks, and three participants lost from each group. The remaining 60 had before-and-after questionnaires analyzed.
lowmegatron reports that pain at rest, during activity and at night decreased significantly in the treatment group, with smaller decreases in the sham group. He says overall fatigue fell from 7.7 to 2.9 with treatment and from 7.3 to 5.9 with sham.
lowmegatron says fatigue, sleep, depression and anxiety were recorded on multiple questionnaire scales. He claims there were "huge improvements" in the treated group compared with sham, and introduces the results that follow.
lowmegatron reports results on the FIS fatigue scale, where lower is better. The active group's mean fell from 69.8 to 30.0 (39.8 points), against a 5-point drop in the sham group.
lowmegatron reports FSS physical fatigue scores, where lower is better. The active group fell from 42.5 to 29.4 (13.1 points) and the sham group from 40.4 to 37.6 (2.9 points).
lowmegatron reports PSQI sleep scores, where lower is better. The active group fell from 6.9 to 4.7 (2.2 points) and the sham group from 6.4 to 6.0 (0.4 points).
lowmegatron reports ESS daytime sleepiness scores, where higher means sleepier. The active group fell from 7.5 to 5.1 and the sham group from 8.3 to 7.9.
lowmegatron reports BAI anxiety scores, where lower is better. The active group fell from 16.9 to 10.4 (6.5 points) and the sham group from 14.5 to 13.7 (0.9 points).
lowmegatron reports BDI depression scores, where lower is better. The active group fell from 16.7 to 9.4 (he states 7.4 points, though the numbers shown differ by 7.3), which he calls significant. The sham group fell from 15.1 to 14.2 (0.9 points).
lowmegatron says past studies show this treatment can reverse the autoimmune and inflammatory processes behind Hashimoto's, and that because these processes are not confined to the thyroid they may explain the symptom relief. The quoted earlier post claims light therapy in Hashimoto's cut T4 needs by 58% and TPOAb by 49%, and cites PMID 22718472.
lowmegatron says the effect of thyroid hormones on these parameters is clearer than the effect of other factors. He claims low tissue levels of active T3 cause all of these symptoms, and that tissue T3 cannot be tested, so single thyroid blood tests reveal nothing about it.
lowmegatron states that all the patients were taking levothyroxine (T4). He argues that levothyroxine-only therapy is unlikely to fully restore tissue T3, which he offers as the reason hypothyroid symptoms often persist in people on levothyroxine alone.
lowmegatron claims that after autoimmunity is reversed (by the light treatment discussed in the thread), the thyroid can make more hormone, including more T3. He says prior human studies found T3 rose by up to 57%, and he thinks this is likely the biggest factor in symptom improvement.
lowmegatron claims the T3 increase from the treatment has the same effect as switching from levothyroxine dosed to TSH to NDT dosed to symptoms and basal temperature. He says the benefit comes from greater T3 availability in tissues, not just blood.
lowmegatron says the exact treatment protocol is critical for good results with this therapy. He states you cannot just sit in the sun or use a random red light for a random time and expect the same benefits.
lowmegatron says near-infrared light is good for general health, but for treatments like this it should be treated like a drug: dose is critical, more is not better, and ignoring dose wastes time and money.
lowmegatron reports the researchers used an Intelect Mobile Laser (Model 2779) from Chattanooga Group, and says LEDs should work too. He says the wavelength was 850 nm near-infrared A rather than visible red, and that slightly lower NIR wavelengths have also worked in other research.
lowmegatron describes the study's dosing parameters: a very small laser beam delivering 100 mW, 16 joules per treatment, split as 2 joules at each of 8 points on the thyroid (4 per side).
lowmegatron points readers to his earlier thread on this treatment's effects on antibodies, thyroid hormones and thyroid structure in Hashimoto's. The quoted thread claims light is the most effective Hashimoto's treatment, listing lower TSH, antibodies and medication use, higher T3, and that 47% no longer needed thyroid meds.
lowmegatron says an equivalent dose might be about 20 seconds per side of the thyroid with a GembaRed handheld LED panel, per Andrew from GembaRed, with contact to the skin. He notes the study laser costs about 3k used.
lowmegatron shares his article on the effects of near-infrared light on Hashimoto's antibodies and thyroid hormone levels.

Detailed stress symptom questionnaire and clinical outcomes provided. Embedded post describes magnesium's effect on blunting stress hormones (cortisol, aldosterone) during exercise and outlines consequences of high aldosterone and cortisol.
Higher progesterone levels in women and higher testosterone and progesterone in men predict lower stress response. Study measured ACTH and cortisol response to Trier Social Stress Test (TSST). Progesterone inhibits HPA axis reactivity in women; testosterone inhibits it in men. Women studied during follicular phase.
Ray Peat explains that thyroid hormone is not a stimulant but corrects sleep disorders caused by hypothyroidism. In hypothyroidism, elevated adrenaline, estrogen, and cortisol with low magnesium disturb deep sleep. T3 with magnesium reliably treats insomnia, cramps, and anxiety. Cited sleep study shows hypothyroid patients have significantly decreased stage 3 and 4 (deep) sleep, which increases after desiccated thyroid treatment. Deep sleep stages essential for physical restoration, immune support, tissue repair, and growth hormone release.
Hypothyroidism increases blood pressure by activating adrenal glands and elevating aldosterone, adrenaline, noradrenaline, and cortisol. Sympathetic and adrenal activation in hypothyroidism is reversible with thyroid hormone treatment. Embedded post describes hypothyroidism increasing oxidative stress (MDA elevation) and atherosclerosis risk; cites Broda Barnes' basal temperature and NDT treatment method reduced heart disease diagnoses by 94% compared to Framingham Study expectations.
Low body temperature associated with dementia; body temperature influenced by thyroid hormone activity. In hypothyroid patients, adding active thyroid hormone T3 reduces dementia risk by 16-30% versus TSH normalization alone. Animal Alzheimer's models show cold exposure increases tau and amyloid beta; raising body temperature via thermoneutral environment lowers amyloid beta and improves memory within a week. UTMB study author Dr. Antonio Bianco states TSH normalization alone insufficient for optimal outcomes.
Subclinical hypothyroidism (elevated TSH, normal T4) treated as harmless but carries risk. TSH itself is harmful, causing insulin resistance and atherosclerosis independently. TSH directly activates TLR4 inflammatory pathway, increases MCP-1 (promoting atherosclerosis), and correlates linearly with insulin resistance (HOMA-IR) even within normal TSH range. Embedded post describes JAMA article recommending TSH <10 and weaning older adults off levothyroxine, citing negative effects of TSH including inflammation, insulin resistance, atherosclerosis, and miscarriage risk; notes T3 excluded from study and lower T3 causes most hypothyroid symptoms.
Single-phrase post with embedded quote on walking benefits.

Author defines stress as energy demand exceeding supply and claims metabolic slowdown through thyroid hormone effects occurs but often undetected in blood tests.
lowmegatron says stress has non-psychological causes as well and quotes Hans Selye's definition: 'The nonspecific response of the body to any demand placed upon it.'
lowmegatron lists claimed stress markers: higher cortisol, glucagon, adrenaline, prolactin, serotonin, growth hormone, free fatty acids, reverse T3 and fat gain, and lower muscle.
lowmegatron argues that 'hidden hypothyroidism' exists because symptoms come from low T3, and problems after hormones leave the gland can still cause hypothyroid symptoms.
lowmegatron says TSH is the most common hypothyroidism test and is assumed 'low = good', but claims stress also lowers TSH, making it an unreliable marker of thyroid hormone activity.
lowmegatron says T4 is the storage form and low T4 can indicate a thyroid problem, but normal T4 does not confirm good activity because T4-to-T3 conversion declines under stress.
lowmegatron says good T3 lab results don't guarantee optimal thyroid activity because T3 must enter tissues and cells and activate receptors, and claims stress disrupts every step.
lowmegatron claims stress hormones reduce T4-to-T3 conversion, lower TSH and raise free fatty acids, and that PUFAs in those FFAs block T3/T4 uptake and receptor binding. He says PUFAs come mainly from seed oils, pork and poultry, and that cells become 'T3-starved' despite normal blood tests.
lowmegatron lists claimed indicators of low tissue thyroid action: feeling cold, high reverse T3, high reverse T3:T3 ratio, hypothyroid symptoms, low resting metabolic rate, and low waking basal temperature.

In 13 women with PCOS, 7 normalized menstrual cycles and 2 became pregnant after vitamin D and calcium supplementation. Calcium carbonate (1,500 mg elemental daily) and vitamin D2 (50,000 units weekly or biweekly, titrated to 25OHD 30-40 ng/ml) were used. Hypothesis: abnormal calcium homeostasis underlies PCOS pathogenesis.
PCOS is nearly 3 times more likely in autoimmune thyroid disease (primarily Hashimoto's). Women with PCOS are about 3 times as likely to have subclinical hypothyroidism, with odds increasing when TSH ≥4 mIU/L. Ray Peat is quoted that PCOS can be produced in animals by thyroidectomy due to impaired ovarian progesterone synthesis.
A 22-year-old with refractory obsessive-compulsive disorder and body dysmorphic disorder that began at age 17 showed significant symptom amelioration with high-dose glycine (50-65 g/day) over 5 years. Psychiatric drugs and therapy failed; glycine allowed resumption of education and social life. Symptoms often recurred when glycine was stopped. Hypothesis: postulated N-methyl-D-aspartate receptor signal transduction deficiency.
Salt, glycine, CO2, progesterone, thyroid hormone and sugar optimize energy and sleep as restorative background processes (Ray Peat quote). Progesterone restores normal sleep when disturbed without inhibiting deep sleep (unlike hypnotics). Hypothyroidism decreases stages 3-4 sleep; desiccated thyroid may increase these. Glycine 3g improves sleep quality and reduces fatigue in sleep-restricted subjects.
Carbohydrates are necessary for optimal conversion of T4 to active T3 thyroid hormone. Decline in serum T3 during no-carbohydrate diet correlated with blood glucose and ketones. Glucose is essential for T3 conversion; carbohydrate restriction mimics fasting and lowers metabolic rate. Fruit, juice and milk are optimal carbohydrate sources. Ray Peat quote on liver regulation of thyroid function via carbohydrate.
T3 thyroid hormone is lower in levothyroxine-treated patients than in healthy subjects at equivalent TSH levels. TSH is not the gold standard for adequate levothyroxine substitution; it reflects only pituitary thyroid hormone levels. Elevated T4:T3 ratio with levothyroxine monotherapy may downregulate T4-to-T3 conversion peripherally. Type 1 and 2 deiodinases appear more effective in pituitary than peripheral tissues.
Quote from footballer Kai Havertz on sports nutrition advice from Chelsea nutritionist recommending Fanta, Coke, and sugar-based snacks (gummy bears, Skittles) which he credits with restoring energy. Shared in context of sports performance, not health claim.
Post shares link (URL not resolved) and embedded quote from LiveAncestral arguing carbohydrates are not essential macronutrients; gluconeogenesis provides glucose from fat and protein. Post discusses historical dietary guidelines (1977: 6-11 grain servings) as serving food industry interests rather than health, and personal carb restriction experience.
Coffee consumption is associated with reduced risk of cirrhosis, liver fibrosis, fatty liver disease, metabolic syndrome, and hepatocellular carcinoma. Risk reduction increases with consumption: 1 cup daily reduces cirrhosis risk by ~50%; 4 cups daily by ~84%. In advanced liver scarring, those drinking 3+ cups daily had ~43% lower rates of liver failure or cancer compared to non-drinkers. Tea and other caffeine sources showed no benefit.
Saturated fat (butter) improves survival in alcoholic liver disease compared to polyunsaturated fat (soybean oil). An RCT found patients with severe alcoholic hepatitis ~3x more likely to die on soybean oil than butter over 2 months. Mechanisms involve PUFA peroxidation producing toxic aldehydes, causing fibrosis and leaky gut, while saturated fat is non-peroxidizable and reduces inflammation and gut permeability. Bacterial endotoxin is identified as a major cofactor.
DHEA increases 11β-HSD2 enzyme activity, which locally inactivates cortisol to cortisone at the tissue level, independent of blood cortisol levels. This reduces cortisol's receptor activation in tissues. Elevated tissue-level cortisol, even with normal blood levels, contributes to insulin resistance, visceral fat, dyslipidemia, hypertension, cardiovascular disease, neurodegeneration, depression, anxiety, sleep impairment, immune suppression, poor wound healing, osteoporosis, muscle wasting, hormone dysregulation, and skin deterioration. Optimal DHEA dosing is 3-5 mg, 1-3 times daily. Higher doses become estrogenic; topical application combined with pregnenolone maximizes anti-cortisol effects while minimizing estrogen conversion. Coffee, aspirin, and vitamin D reduce activity of the related 11β-HSD1 enzyme.

Off-topic question with no health content.
lowmegatron replies "Damn right they were." The referent is unclear. The parent only asks "Is retarditude ancestral?", and this reply's own text adds no substantive claim.
Hypothyroidism reduces CO₂ production because mitochondrial CO₂ production depends on thyroid hormone T3. End-tidal CO₂ measurement reflects alveolar and arterial CO₂ levels. Contrary to expectations, hypothyroid patients show higher alveolar ventilation (lower end-tidal CO₂), indicating hyperventilation rather than hypoventilation. The mechanism may involve direct effects of TRH on respiratory center or local lung changes. Respiratory rate alone does not define hypo/hyperventilation; arterial CO₂ is the definitive measure.
Humorous post sharing a video comparing Coca-Cola and Coca-Cola Zero, framed as demonstrating how to remove water from Coke.
Progesterone lowers blood pressure through three mechanisms: dilating blood vessels, preventing adrenaline-induced blood pressure rises, and blocking calcium channel uptake in vascular smooth muscle (similar to calcium channel blocker drugs). A small clinical trial of 10 hypertensive patients (6 men, 4 postmenopausal women, mild to moderate, untreated) showed progesterone caused significant blood pressure reduction compared to placebo and baseline, suggesting antihypertensive rather than hypertensive action.
Untreated hypothyroidism increases anxiety risk nearly 4-fold. Mechanisms include elevated histamine, catecholamines (adrenaline and noradrenaline), cortisol, lactate, hyperventilation, and reduced CO₂ production. A case study shows severe psychiatric manifestations (delusions, hallucinations, insomnia, anxiety, disorganized speech) in a hypothyroid patient (TSH >100) that resolved within one day of levothyroxine initiation and remained absent at 6-month follow-up without psychotropic medications.
Thyroid hormone regulates growth in children. Hypothyroid children are shorter than average; hyperthyroid children are taller. Historical and contemporary evidence shows thyroid hormone treatment improves height and intelligence in hypothyroid children. Genetic thyroid hormone resistance is associated with 6-fold increased short stature risk if untreated. Historical case series: treatment improved growth rates (e.g., 7-year-old grew 1 inch in 2 years before treatment, 1 inch in 2 months on thyroid; 5-year-old gained 1 inch in 9 weeks; 18-year-old 34-inch-tall youth gained 2 inches in 9 weeks). Modern study confirms lower height z-scores in acquired hypothyroidism; hyperthyroid children show increased height and low BMI.

Topical thyroid hormone (T3) reduces scar formation in burn and skin graft wounds, producing flatter, softer, more supple scars. Animal studies in rats showed T3 modified collagen synthesis and deposition, increased hydroxyproline content in normal and grafted skin, and histology confirmed softer, more supple scar tissue with reduced hypertrophic scarring.
Thyroid hormone (T3) treats radiation burns and fibrosis, even decades after exposure. Clinical study of 75 patients with 2–30 year old radiation injuries showed approximately two-thirds with ulcers and fibrosis achieved good-to-excellent improvement on pharmacologic T3 doses. Animal studies confirmed the effect by measuring hydroxyproline (collagen proxy); T3 given before, immediately after, or weeks after irradiation prevented or reversed collagen accumulation.
Soy-based phytoestrogens can worsen subclinical hypothyroidism to clinical hypothyroidism and interfere with levothyroxine absorption in children. High-dose soy phytoestrogen (16 mg) poses 3× increased risk of progression to clinical hypothyroidism. Case reports describe hypothyroid children who became profoundly hypothyroid on soy milk despite levothyroxine treatment.

Free T3 increased 20%, free T4 increased 40%, TSH decreased 55% (from 8.3 to 3.7). Author attributes benefits to increased CO₂ retention and reduced stress hormones.
Author lists sixteen factors that can impair thyroid hormone response: elevated free fatty acids, low total cholesterol, levothyroxine monotherapy, inappropriate T3 dosing, empty-stomach T3 administration, wrong T4:T3 ratio, TSH-only dosing, micronutrient insufficiencies (sodium, magnesium, calcium, retinol, zinc, selenium, vitamin D), high polyunsaturated fat intake, estrogen dominance, protein imbalance, and iron/iodine imbalance. Embedded post emphasizes carbohydrate's role in hepatic T3 production.
Hypothyroidism is an overlooked cause of hiatal hernia. Reduced thyroid hormone and elevated stress hormones (cortisol in relation to testosterone and DHEA) weaken connective tissues. Research shows hypothyroidism is an early sign of hiatal hernia and gastroesophageal reflux disease (GERD), associated with gastrointestinal motor-evacuatory disturbances rather than acid exposure. Severe hypothyroidism causes esophageal peristalsis disturbances, myxedema-related oropharyngeal dysphagia, and hiatal hernia.

ADHD and hypothyroidism share mechanisms of decreased oxidative metabolism, lowered ATP and CO2 in the brain. Increasing CO2 may improve ADHD as demonstrated in rodent experiments and case reports. Acetazolamide, which increases CO2 by inhibiting carbonic anhydrase, improved ADHD symptoms in a case report and reduced ADHD-linked behaviors in mice; T3 increases oxidative metabolism and CO2 production.
lowmegatron quotes Ray Peat on impaired brain oxygen metabolism and attention deficit, with coffee improving focus. He says type 2 diabetes and epilepsy are linked to 2-5 times higher ADHD diagnosis. He adds a disclaimer that this is an explainer on thyroid hormone and CO2 in ADHD, not a prescription to take acetazolamide, and advises checking contraindications and speaking with a doctor. He lists three references: a case report, a rat study and a rat hypothyroidism study.

lowmegatron argues thyroid function adjusts to energy availability, so undereating or overexertion can reduce thyroid hormone production, conversion or tissue response and lower metabolic rate. He warns against combining fasting with intense exercise and suggests mild caloric restriction balanced with adequate intake.
lowmegatron says goitrogens can interfere with thyroid hormone levels before a goiter appears, names cruciferous vegetables and soy as main offenders, says cooking reduces them, and says iodine insufficiency worsens their effect.
lowmegatron claims polyunsaturated fats from seed oils and high-PUFA-fed non-ruminant animals disrupt thyroid hormone production, transport and binding, and that stress releases them as free fatty acids. He recommends mostly saturated fats (coconut oil, butter, tallow and similar) and lists many PUFA oils including fish oil to avoid.
lowmegatron says phthalates and BPA/S/F impair thyroid gland function and peripheral hormone conversion, and that BPA blocks thyroid hormone at the receptor. He lists sources such as fragranced cosmetics, plastic containers and bottles, can linings, dust and receipts. The quoted parent reports a rat study where BPA altered T3, T4 and TSH and ginger gave partial protection.
Vitamin E protects thyroid by inhibiting oxidative stress and lipid peroxidation. Higher intake associated with lower subclinical hypothyroidism and thyroiditis risk in men; higher vitamin E status associated with lower TSH and higher T4 in Hashimoto's women.

Dreaming as marker of fractured sleep. Author correlates dream recall with poor sleep, gastrointestinal issues, or infection. Distinguishes between dreaming and dream recall. Cites arousal-retrieval model (1970s) tested in 2014 study using polysomnography. High dream recallers showed double intrasleep wakefulness (~30 vs ~14 min) and longer awakenings (1.90 vs 0.95 min). Brain reactivity to sounds during sleep was heightened in high-recallers. Embedded post discusses cyproheptadine's effects on deep sleep for glucose/insulin regulation, blood pressure, and brain detoxification.
Checking breathing once or twice daily can interrupt stress-induced hyperventilation, which lowers CO₂ and impairs metabolism and oxygen delivery. Slowing breath or bag breathing rebuilds CO₂ tolerance and may improve mood, clarity, and blood pressure. The Bohr effect explains how higher blood CO₂ helps hemoglobin release more oxygen.
Ray Peat quote: butter and coconut oil contain short- and medium-chain saturated fatty acids that are easily metabolized, inhibit histamine release, promote cancer cell differentiation, counteract stress proteins, decrease prolactin receptor expression, and promote T3 receptor expression.

Author reports new research showing near-infrared light reduces anxiety, depression, fatigue, pain and sleep problems in Hashimoto's hypothyroidism patients within 3 weeks, despite continued levothyroxine therapy.
lowmegatron describes a randomized sham-controlled study of Hashimoto's patients, 33 per group, where the control group's laser device was not turned on, only its display. It follows the parent's claim about near-infrared light for Hashimoto's.
lowmegatron gives trial details: two treatment sessions per week for 3 weeks. Three participants were lost from each group because they stopped treatment or changed medication dose, and one was listed as "lost to follow-up." The remaining 60 had their before-and-after questionnaires analyzed.
lowmegatron reports that pain at rest, during activity, and at night decreased significantly in the treatment group, with relatively small decreases in the sham group. Overall fatigue fell from 7.7 to 2.9 in the treatment group and from 7.3 to 5.9 in sham.
lowmegatron says fatigue, sleep, depression, and anxiety were recorded on multiple questionnaire scales and claims there were "huge improvements" in the treated group versus sham. It introduces the following results.
lowmegatron reports FIS (fatigue impact on daily life, lower is better) fell from 69.8 to 30.0 in the active group (39.8 points), with a 5-point drop in sham.
lowmegatron reports FSS (physical fatigue severity, lower is better) fell from 42.5 to 29.4 (13.1 points) in the active group and from 40.4 to 37.6 (2.9 points) in sham.
lowmegatron reports PSQI (sleep quality, lower is better) fell from 6.9 to 4.7 in the active group and from 6.4 to 6.0 in sham.
lowmegatron reports ESS (daytime sleepiness, higher means sleepier) fell from 7.5 to 5.1 in the active group and from 8.3 to 7.9 in sham.
lowmegatron reports BAI (anxiety symptoms, lower is better) fell from 16.9 to 10.4 in the active group and from 14.5 to 13.7 in sham.
lowmegatron reports BDI (depression symptoms, lower is better) fell from 16.7 to 9.4 in the active group, described as significant, and from 15.1 to 14.2 in sham.
lowmegatron claims past studies show this treatment can reverse the autoimmune/inflammatory processes behind Hashimoto's, and that since these are not confined to the thyroid they may play a significant role in symptom reduction. The quoted post cites earlier light-therapy Hashimoto's results (PMID 22718472) with reductions in T4 need and TPOAb.
lowmegatron asserts that low tissue levels of active T3 cause all these symptoms, that tissue T3 is not testable, and that single thyroid blood tests tell us nothing about it.
lowmegatron notes the patients were all taking levothyroxine and claims levothyroxine-only therapy is unlikely to fully replenish tissue T3, which he offers as why hypothyroid symptoms often persist.
lowmegatron claims that after autoimmunity is reversed the thyroid can release more hormone including active T3, citing "prior human studies" that found T3 up to 57% higher, and calls this likely the biggest factor in symptom improvement. The quoted post describes a Brazilian study (PMID 23316383) on thyroid vascularization with 830 nm light at 50 mW.
lowmegatron claims the T3 increase has the same effect as switching from levothyroxine dosed to TSH to NDT dosed to symptoms and basal temperature, attributing the benefit to greater tissue T3 availability.
lowmegatron says the exact treatment protocol is critical and that sitting in the sun or using a random red light for a random time should not be expected to give the same benefits.
lowmegatron says near-infrared light is good for general health but, for treatments like the one in the thread, should be treated like a drug. He claims dose is critical and that more is not better.
lowmegatron describes the device in the study: an Intelect Mobile Laser (Model 2779) from Chattanooga Group, at 850 nm (near-infrared A). He says LEDs should also work and that slightly lower near-infrared wavelengths have worked in other research.
lowmegatron reports the study's laser parameters: 100 mW, 16 J per treatment, and 2 J at each of 8 points on the thyroid (4 per side).
lowmegatron points readers to an earlier thread on this light treatment's effects on antibodies, thyroid hormones and thyroid structure in Hashimoto's. The quoted thread claims light is the most effective Hashimoto's treatment, with lower TSH, weight and antibodies, and that 47% no longer needed thyroid meds.
lowmegatron relays a GembaRed representative's estimate that about 20 seconds per side of the thyroid with its handheld LED panel, used in contact with the skin, may equal the study dose. He notes the study laser costs about $3k used.
lowmegatron quotes Redlightman's Joe on approximating the study dose with the Mini 830. Joe argues the device is about 100x more powerful than the study laser, so a 2-second session would match it, though he recommends 5–8 minute sessions.
lowmegatron says accidental exposure to owners' transdermal estradiol gel caused hair loss in dogs. The quoted case reports describe the alopecia resolving after the exposure stopped.

lowmegatron says thyroid hormones affect hair growth and pigmentation, and that hair follicles can convert T4 to T3. It cites a human follicle study finding functional thyroid hormone receptors, and shows photos of severe hypothyroidism and recovery.
Low thiamine intake is associated with constipation. Genetic variants in SLC35F3 and XPR1 transporters reduce thiamine cellular uptake and phosphorylation, limiting active thiamine (thiamine pyrophosphate) production and blunting response to dietary thiamine. Affected individuals may require higher supplemental doses. Thiamine modulates gut motility; thiamine deficiency causes GI beriberi and disordered gut motility.

He reports values of about 756 pmol for untreated hypothyroid patients and 767 for levothyroxine-treated patients, versus 1990 for NDT-treated and 2,074 for healthy people. He describes an NDT protocol dosed by symptoms rather than TSH, and reports that hypothyroid symptoms were higher on levothyroxine than on NDT. He adds a disclaimer that he does not claim NDT is superior to properly dosed synthetic T3+T4, that thyroid hormones should be taken under medical supervision, and that this is not medical advice.
Author explains levothyroxine normalizes TSH while leaving tissues T3-deficient, cites rat study showing normal blood tests despite low tissue T3, and describes how this creates hidden hypothyroidism. Discusses peripheral T4-to-T3 conversion inadequacy and presents human data showing >20% of post-thyroidectomy patients have abnormal T3/T4 ratios despite normal TSH.
lowmegatron gives two references, one on combined T4+T3 treatment in thyroidectomized rats and one on levothyroxine monotherapy in athyreotic patients. He notes that the man in the accompanying image was treated with NDT USP, which contains T3. He explains that he uses older images because treatment back then was guided by symptoms, basal temperature and/or basal metabolic rate, which he considers more appropriate.

Author questions whether a news item is real or AI-generated hallucination, with no specific health content.
lowmegatron says stinging nettles are a source of serotonin and histamine. He quotes text that nettle sting fluid contains formic acid, leukotrienes, acetylcholine, histamine and serotonin, with estimated serotonin per sting. The quoted parent lists things he says lower or raise histamine.
Author makes assertion that Bryan Johnson does not have Parkinson's and that news reports were hallucinations, referencing a previous post about AI-generated content.
Dock leaves contain anti-serotonin and anti-histamine compounds that counteract nettle sting symptoms by antagonizing serotonin and histamine in the sting fluid; mechanism demonstrated in 1947 research on tissue preparations.
Serotonin can cause hypoglycemia, which suppresses T3 and reduces thyroid hormone conversion and output; carbohydrate refeeding restores T4-to-T3 conversion within 72 hours via glucose-dependent mechanisms; thyroid function depends on adequate glucose.
lowmegatron claims vitamin K2 can improve insulin sensitivity. He cites PCOS women taking 90 µg MK-7 for 8 weeks who had lower HOMA-IR, and men taking 30 mg MK-4 for 4 weeks who had better insulin sensitivity, possibly via carboxylated osteocalcin. The quoted parent discusses hypothyroidism and insulin resistance.
Natural desiccated thyroid (NDT) contains both T4 and T3 in ~4-5:1 ratio; T3 content helps activate T4-to-T3 conversion enzyme; NDT effective for many patients; synthetic T3+T4 combinations often equivalent; individual response varies; OTC bovine glandulars lack standardization.
Sodium bicarbonate (baking soda) 4 grams reduces amniotic fluid lactate and increases spontaneous vaginal delivery rates by 17-20% in women with labor dystocia by restoring uterine muscle contractility.
Baking soda lowers aldosterone via sodium and bicarbonate; chronically elevated aldosterone causes inflammation, fibrosis, and cardiovascular disease; bicarbonate supplementation mimics CO2 retention and normal thyroid function by maintaining cellular carbon dioxide and stabilizing cells.
The author quotes a passage saying psychological stress may accelerate hair greying, that mouse work links norepinephrine signaling to melanocyte stem cell depletion, and that human greying is at least sometimes reversible. The quoted post (his own) adds that the mechanism resembles fasting-induced hair loss research and that thyroid deficiency raises norepinephrine; this reply itself only contains the quoted passage.
Author critically examines claims that MTHFR polymorphisms interfere with thyroid hormone T4-to-T3 conversion, finding no primary research support. Presents evidence that thyroid hormone is upstream of MTHFR function via FAD availability, and cites association data linking MTHFR C677T to hypothyroidism risk without establishing causative mechanism for conversion defects.
Author challenges missyTHX1138 to provide evidence for claims that MTHFR causes thyroid conversion issues, stating they have repeatedly encountered such claims without supporting evidence and cannot find any themselves.
Author reposts skeptical comment about Bryan Johnson health claims, suggesting marketing or data collection motives rather than endorsing the health claims themselves.
Author shares Ray Peat anecdote about pregnant woman whose vivid stretch marks reportedly resolved in three days after consuming eggs, milk, and oysters, in response to question about foods increasing progesterone and lowering aldosterone.
Author presents research showing taurine 1g three times daily for 2 weeks ameliorated insulin resistance and beta cell dysfunction in non-diabetic obese men given IV lipids to simulate elevated free fatty acids. Mechanism suggested as antioxidant activity reducing 4-HNE, a driver of Alzheimer's, cancer, and liver damage.
Author quotes Ray Peat on salt's role in lowering aldosterone and preventing tissue degeneration, fibrosis, aging, heart failure and edema. Describes low-sodium diet as dangerous and discusses aldosterone's multiple effects on cardiovascular and tissue health.
lowmegatron quotes a passage that is attributed to Ray Peat in the parent post. It says aldosterone is part of the renin-angiotensin-aldosterone system and raises blood pressure. It claims parathyroid hormone and aldosterone reduce energy production and shift cells toward lactic acid production. It adds that parathyroid hormone pulls calcium from bone, so blood calcium rises when both are high.
lowmegatron quotes a passage claiming that low blood sugar can start a process in which the kidneys release renin and aldosterone is produced, leading toward hypertension, inflammation and degeneration. It also claims that not eating enough salt raises aldosterone.
lowmegatron quotes a passage claiming that hyponatremia occasionally occurs in hypothyroid younger people. It says thyroid-made carbon dioxide helps retain sodium, and that aldosterone saves sodium but makes the kidneys lose magnesium. It claims that extra salt is protective because it keeps the adrenals from making aldosterone, so the kidneys retain magnesium.
lowmegatron quotes a passage claiming that vitamin D, zinc, anabolic and protein-related factors such as vitamin A, and a balanced calcium-phosphate ratio suppress aldosterone. It says the ratio is generally too high in calcium, and that calcium works with vitamin D to hold down aldosterone, which it calls the "major brittleizing hormone".
lowmegatron quotes a passage claiming that natural steroids derived from pregnenolone, progesterone or DHEA help with water retention, edema and heart failure. The quote says this is because they antagonize aldosterone, which it claims causes inflammation and water retention.
lowmegatron quotes a passage claiming that leaky blood vessels, for example from hyperventilating, reduce blood volume. It says this activates the kidneys' pathway to increase aldosterone, which keeps sodium in the bloodstream so blood can absorb water and edema does not form.
lowmegatron quotes a passage claiming that salt intake suppresses aldosterone, so restricting salt raises aldosterone and blood pressure. It mentions Tom Brewer's approach of recommending milk, fruit and vegetables, and claims this also increased calcium and vitamin D intake.
lowmegatron quotes a passage claiming that with low thyroid function the kidneys lose sodium and cells cannot retain magnesium. It says increasing sodium compensates and turns off aldosterone, lowering inflammation and magnesium loss. It claims Brewer and his predecessors showed sodium alone commonly cured the whole problem.
lowmegatron quotes a passage claiming that cutting sodium raises aldosterone, which retains sodium at the cost of potassium and magnesium. It says chronic high aldosterone is pro-inflammatory, and that getting more calcium, magnesium and potassium than needed is a safety precaution.
lowmegatron quotes a passage claiming that estrogen activates the adrenal cortex to make aldosterone and cortisol, and that adequate progesterone blocks their peripheral effects. It says progesterone can substitute for their essential beneficial effects when the adrenals are removed, and protects against their excess as it does against estrogen toxicity. The quoted post in context is a Ray Peat quote about eggs, milk and oysters and stretch marks.
Author presents research finding that hypothyroidism doubles aldosterone and is related to high blood pressure through increased daytime diastolic values and noradrenaline. Cites study showing thyroid hormones participate in systemic arterial blood pressure homeostasis.

Carboxytherapy (CO2 gas injections) improves stretch marks with objective 3D camera measurements of depth and texture; 55-65% improvement in indentation and texture; 8 sessions over 4 weeks; striae rubra (red, new) more treatable than striae alba (white, old); includes Ray Peat anecdote in embedded quote.
lowmegatron says many people believe nothing can be done for stretchmarks, and quotes his earlier post on carboxytherapy (CO2 gas injections). That post cites a 20-woman study of 8 sessions with reported improvements on 3D-camera metrics of roughly 55–65% and clinician-graded improvement, with better results for newer red marks than older white ones. The attached link is not supplied.
Carboxytherapy (CO2 injections) reduces cellulite, causing reduction from degree III to degree II; characterized as effective spot reduction in fat.
lowmegatron says human studies of CO2 injections (carboxytherapy) reported reduced thigh and abdomen circumference, increased skin elasticity, and a cellulite reduction "from degree III to degree II".
lowmegatron begins describing a rodent study testing whether CO2 treatment might help obesity. Mice were made obese with a 60% fat diet and randomly split into two groups.
lowmegatron explains that gases were injected into the mice's inguinal fat pads, and that "iWAT" in the images means inguinal white adipose tissue.
lowmegatron describes the protocol: one group got air in both pads, the other got air in one pad and CO2 in the other. Injections were 1cc per pad, every other day for 14 days.
lowmegatron reports that CO2-treated mice had lower body weight and blood glucose, mostly from fat loss, with shrunken fat pads and fat cells. FASN, a fat-synthesis gene he says is linked to cancer, was reduced.
lowmegatron says CO2 decreased FABP4, a gene involved in fat and triglyceride formation, and upregulated UCP1, an uncoupling gene he says contributes to increased energy expenditure and fat loss.
lowmegatron quotes research interest in raising UCP1 by gene transfer or other upregulation methods for obesity. He opines that "Upping your own CO2 production is probably a better option."
lowmegatron lists four carboxytherapy sources on fat loss, localized adiposity, skin irregularity and cellulite. The thread also quotes a related post on stretchmarks improving after carboxytherapy.

Case report of hip pain and joint degeneration caused by undiagnosed severe hypothyroidism, with complete resolution following thyroid hormone replacement. Initial misdiagnosis over 2-3 months; imaging showed hip effusion, femoral head demineralization and acetabular damage; treatment with levothyroxine reversed all changes within 2-3 months with normalized labs and normal follow-up imaging at one year.
Observational studies show inverse association between dietary iodine intake and remission rates in Graves' hyperthyroidism. Higher iodine intake correlates with lower remission probability, higher antibody titers, and higher medication requirements. Research suggests low-iodine diet may reduce thyroid hormone production and lower medication doses needed for treatment.
Case report of woman misdiagnosed with seronegative rheumatoid arthritis for 2 years presenting with progressive PIP joint pain, stiffness and swelling. Diagnosed with severe hypothyroidism (TSH 65.9); treated with levothyroxine 100 mcg daily; joint swelling disappeared within 3 months, grip strength increased, no residual pain except on maximum flexion. Follow-up radiographs showed soft tissue swelling resolution and no progression of erosions; remains well 2 years later.
Nuclear measurement study of 15 hypothyroid patients showed extracellular water hyperhydration with liquid accumulation in interstitial space. Water retention severity correlates with age and disease gravity but not duration. Mechanism involves low cellular T3 limiting ATP and CO2 production, reducing sodium/potassium regulation; mucopolysaccharide gel buildup and stress-hormone-induced capillary leakiness.

Hypothyroidism can cause atrial fibrillation; case study and mechanism explained. Case reports show levothyroxine treatment resolved AF symptoms. Studies indicate up to 8% of AFib patients are hypothyroid. Author notes hyperthyroidism is a more common AFib cause; normalizing thyroid hormone levels corrects the imbalance.
US hypothyroidism prevalence increased from 9.5% to 11.7% (2012-2019), a 23% relative increase driven by changes in older adults (50+). Author compares prevalence data from medical claims/prescriptions to older survey-based lab values, noting methodological differences in case definition.
Author discusses limitations of TSH testing for hypothyroidism diagnosis. TSH is blind to peripheral T4-to-T3 conversion and thyroid hormone resistance. Gene variants, stress, and diet affect conversion and activity independent of TSH. Contrasts TSH-based prevalence (10%) with Broda Barnes' symptom-based approach (40% responsive to NDT treatment).
Quoted statement from Ray Peat on cardiac rhythm stabilization and AFib risk factors. Claims vitamins D, K, calcium stabilize heart rhythm. Estrogen causes hyperventilation and increases AFib risk; progesterone has opposite effects. Thyroid T3 essential for cellular magnesium retention. Dietary recommendations: milk and orange juice for minerals, seafood weekly for trace minerals.
Author claims levothyroxine treatment does not normalize thyroid hormone levels despite normal TSH. Cites research showing levothyroxine-treated patients with normal TSH have lower T3 than healthy subjects. Explains mechanism: pituitary has better T4-to-T3 conversion than peripheral tissues, causing false TSH-based assessment. Argues TSH cannot be gold standard for adequacy.
Case series of 5 children misdiagnosed with rheumatic/inflammatory conditions (hypermobility, fibromyalgia, juvenile rheumatoid arthritis, chondromalacia, dermatomyositis) ultimately caused by hypothyroidism. All improved with thyroid replacement; 3 recovered fully. Author explains low cellular T3 activity as cause and notes overlap with non-thyroid diagnoses.
Quoted Ray Peat statement on thyroid T3 for insomnia and menopause, and sodium chloride for sleep-inducing effects. Claims T3 rapidly restores normal relaxation rate to calf and heart muscle. Sodium chloride at bedtime lowers adrenaline, promotes glucose absorption, spares magnesium. Connects thyroid function to glucose efficiency and adrenaline regulation.
Author promotes PEA (palmitoylethanolamide) supplement for depression and anxiety via mast cell stabilization and TLR4 pathway inhibition.

Study showed 50% increase in ectopic beats at 130 mg/day versus 320 mg/day intake. Over 50% of people don't consume enough magnesium. Survey found atrial fibrillation recovery associated with >2x RDA magnesium intake.
Comprehensive list of 18+ factors that suppress thyroid hormone T4-to-T3 conversion, including fasting, low-calorie diets, nutrient insufficiencies, stress, sleep deprivation, exercise imbalance, inflammation, and hormone imbalances. Solutions are inferred from identified causes.
Chromium picolinate at 1,000 mcg taken with levothyroxine reduces T4 absorption by ~17% over 6 hours in small study of 7 healthy volunteers. Mechanism is similar to ferric ion binding thyroxine causing malabsorption. Embedded quote discusses soy phytoestrogen interference with levothyroxine absorption and thyroid function.

Embedded quote discusses over-exercise lowering active T3 hormone via cortisol and prolactin mechanisms; carbohydrate/calorie support and creatine mentioned as potential aids.
Ciprofloxacin antibiotic reduces levothyroxine T4 absorption by 39% based on small study measuring 6-hour area under curve. Mechanism involves inhibition of intestinal T4 uptake transporter (possibly OATP family). Embedded quote is personal anecdote about refusing ciprofloxacin during appendicitis due to mitochondrial toxicity concerns and successful use of alternative antibiotics.
Baking soda and carbon dioxide administration slowed cancer spread in animal models of prostate and breast cancer. Ray Peat explains mechanism: bicarbonate provides sodium and CO2 to suppress lactic acid production, allowing tissue healing instead of continued growth. Low thyroid, calcium, vitamin D, and sodium all limit ability to produce sufficient CO2. Historical use of CO2 therapies documented.
Magnesium absorption is dose-dependent; splitting doses throughout day optimizes absorption relative to single large dose. Four 100 mg doses absorb ~50% more than single 400 mg dose (~170 mg vs ~110 mg). Relative Mg absorption inversely related to ingested dose due to intestinal permeability limitation. Study compared bolus vs. distributed consumption of Mg-rich water with same total dose.

Magnesium deficiency lowers thyroid hormone T3 in animals (chicks and rats) and may impair thyroid function in experimental type-2 diabetes; magnesium treatment shows partial restoration of thyroid function. No equivalent human research located by author.
Low serum magnesium is associated with 3-4x increased likelihood of hypothyroidism, Hashimoto's disease, and thyroglobulin antibody positivity. Mechanisms involve immune dysregulation, cellular oxidative stress, energy metabolism, and mitochondrial function. Relationship may be bidirectional. Magnesium supplementation can improve thyroid function.
250 ml carbonated water increases satiety and reduces hunger through CO2-induced oral stimulation, affecting gastric motility rhythms. Embedded quoted post discusses calcium deficiency as potential driver of overeating and calcium supplementation effects on appetite control during weight loss.
Hypothyroidism causes impaired muscle relaxation in skeletal and cardiac muscle, leading to continuous partial contraction and stiffness before fibrosis develops. Inadequate thyroid hormone prevents proper diastolic relaxation and complete contraction, creating functional heart failure correctable by thyroid supplementation. Hypothyroidism can cause atrial fibrillation in up to 8% of AF cases.
Ray Peat quote on energy-deprived cells producing histamine; experimental study showing hypothyroidism increased mast cells 4.5x and histamine 50% in rats.

Cites studies on K2 absorption from distal small bowel and antibiotic association with reduced hepatic K2. Embedded post details K2 effects on insulin sensitivity in PCOS and healthy men via osteocalcin carboxylation.
TSH can be lowered by substances other than thyroid hormones; fasting reduces TSH secretion and cortisol elevation mediates this effect, suggesting mild cortisol elevations can significantly decrease TSH levels.
lowmegatron calls magnesium oil the 'placebo king' because it does not raise serum magnesium. He notes that many people report benefits such as less pain, cramps, better sleep, and hair, skin and nail improvement. He suggests that the research on its availability may be poor, or that blood tests miss effects elsewhere in the body.

lowmegatron argues that extreme caloric restriction and intermittent fasting cause hair loss. In his account, stress hormones raise lipolysis, and free fatty acids and fat oxidation kill hair follicle stem cells. Topical vitamin E prevented this in fasted mice. He cites an 18% slower hair growth in a human trial of 18-hour fasting.
Low thyroid hormone T3 is part of metabolic slowdown during undernutrition. Restoring T3 raises resting energy expenditure. In anorexia nervosa patients, 32% increase in T3 associated with 13% increase in resting energy expenditure independent of fat-free mass.
T3 signaling reflects energy and nutritional abundance. Supplementing thyroid hormone in a malnourished body is cautioned against; small doses of T3 (50 mcg) without adequate nutrition compared to fasting in terms of inefficacy.
Levothyroxine (T4) normalizes TSH but does not correct low metabolic rate in obese hypothyroid women. Poor T4-to-T3 conversion limits efficacy. Natural desiccated thyroid (NDT) and T3 supplementation produce superior weight loss outcomes compared to levothyroxine alone, even at equivalent TSH ranges. Multiple studies demonstrate preference for T3-containing regimens.
Magnesium supplementation significantly improves insulin resistance in both diabetic and non-diabetic subjects with low baseline magnesium levels. Four-month supplementation reduced insulin resistance scores roughly in half. Multiple trials reviewed with different formulations and patient populations (obese, pre-diabetic, chronic kidney disease).

Thyroid hormone depresses noradrenaline and adrenaline secretion by blocking cellular production. This mechanism explains why hypothyroidism causes anxiety and high blood pressure.
Ray Peat reports that chewing 5 mcg Cytomel (synthetic T3) rapidly restores memory within 3–5 minutes, with peak effect at 90 minutes. Dose of 25 mcg daily caused hypothyroid arrhythmia (heart pauses every 6 seconds lasting 1–2 seconds) within weeks; 10 mcg Cytomel immediately restored normal rhythm. Thyroid supplements had similar effect in Peat's acquaintances with arrhythmia and circulation problems from hypothyroidism.
Exercise with inadequate caloric intake suppresses thyroid hormone conversion (low-T3 syndrome) as energy preservation response. Study of 27 untrained women at 70% aerobic capacity found abrupt T3 reduction (16%) and fT3 reduction (9%) between 19.0 and 25.0 kcal/kg lean body mass, and fT4 increase (11%) and rT3 increase (22%) between 10.8 and 19.0 kcal/kg. Increasing energy availability to 25 kcal/kg LBM without reducing exercise may prevent athletic amenorrhea.
Ray Peat reports consuming 50 cups of coffee daily for years while hypothyroid to manage stress, migraines, and fatigue. Within days of starting thyroid supplement, coffee craving disappeared and intake spontaneously dropped to 4–5 cups daily.

The author says hypothyroidism is not one condition. The term covers several conditions that lead to low thyroid hormone activity. They define true hypothyroidism as the thyroid gland being unable to produce enough hormone, for multiple reasons.
The author defines primary hypothyroidism as a problem in the thyroid gland itself. Secondary is the pituitary failing to stimulate the thyroid, and tertiary is the hypothalamus failing to stimulate the pituitary.
The author claims Hashimoto's is the main cause of primary hypothyroidism and needs different handling from secondary or tertiary forms. They say TSH and T4 tests are good at flagging severe primary cases. TSH is often low or normal in secondary and tertiary cases, and neither test shows T3, which they call the critical component.
The author claims hypothyroid symptoms are mostly caused by low thyroid hormone activity inside cells. They say T3 is the active hormone but the thyroid makes mostly T4, which must be converted. They also claim that the TSH rise in primary hypothyroidism is inflammatory and affects other organs, notably the heart.
The author says low thyroid hormone activity can cause hypothyroid symptoms even when the thyroid produces enough hormone. They describe this as not true hypothyroidism and not medically recognized as such, because the thyroid, pituitary and hypothalamus work, yet symptoms are similar due to low T3 activity.
The author says decreased conversion of T4 (which they call the inactive hormone) to T3 can lower T3 and cause hypothyroid symptoms in someone who would not be diagnosed as hypothyroid. They claim there are many causes of poor conversion and that the cause must be identified to fix it.
The author claims TSH and T4 are often normal in people with conversion issues. Those people may be told their thyroid is fine, which may be true, but they can still have a thyroid hormone problem causing symptoms.
The author claims conversion issues are often dismissed, with people put on "horror drugs" for misdiagnosed symptoms. They say a T3 test may detect a conversion problem that TSH or T4 misses, that the reverse T3 to T3 or T4 ratio is often more telling, and that reverse T3 is made from T4, wasting potential T3.
The author says even T3 blood tests are imperfect because they sample only the circulating hormone pool, while hormones are also converted and used inside cells. They add that problems moving hormone from blood into tissues mean even optimal T3 and T4 results are not fully reliable.
The author presents body temperature as a useful indicator of overall thyroid hormone activity. They describe Broda Barnes's Basal Temperature Test, an at-home test with a liquid thermometer held in the armpit for ten minutes on waking, and say Barnes argued hypothyroidism is vastly underdiagnosed.
The author states that basal readings below 97.8 °F (36.6 °C) indicate hypothyroidism and readings above 98.2 °F (36.8 °C) suggest hyperthyroidism. They caution that other factors affect temperature and that the test is not perfect.
The author says women's basal temperature varies across the menstrual cycle, peaking just before menstruation and lowest at ovulation. They advise recording it on the second and third days after menstruation begins during menstrual years, and on any day before menarche or after menopause.
The author claims birth control pills and HRT override natural hormonal fluctuations behind basal temperature changes. They say pills either abolish the early-follicular trough or replace it with an elevated or erratic baseline, so Barnes's test cannot reliably reflect thyroid status in users. They say only women not exposed to synthetic progestins or estrogens keep the low point, and the same applies to HRT.
The author says levothyroxine (T4) is the most common treatment for true hypothyroidism but must be converted to T3, and claims conversion is rarely optimal on levothyroxine alone. They claim adding some T3 "kickstarts" conversion and gives a stable T3 supply through the day, and that blood tests can be normal while T3 activity is suboptimal and symptoms persist.
Lowmegatron claims TSH responds well to levothyroxine but ends up over-suppressed relative to the thyroid hormone available to cells. He says a low TSH does not mean thyroid hormone is adequate. He argues that required doses and T4:T3 ratios vary hugely between people, comparing this to insulin dosing in type 1 diabetes.
Lowmegatron claims diet and lifestyle determine thyroid gland health, hormone conversion, and uptake and activity in cells. He says stress and nutritional deficiencies can quickly impair conversion, leaving low thyroid activity with normal TSH and T4. He relays an anecdote about a woman who improved after dietary changes and replacing some workouts with walks.
Lowmegatron claims that even large doses of T3 may not work if nutrition is inadequate, and that a high-stress state tends to block T3.
Lowmegatron says simple questions about hypothyroidism have no one-size-fits-all answer and that anyone offering one doesn't grasp the problem. He notes he has written at length on social media, praising X's search and linking, and admits one post can't cover everything.
Lowmegatron invites readers who need help understanding hypothyroidism and low thyroid hormone to check out his video course and online community, with a link.

Author shares URL and embedded quoted post by lowmegatron on thyroid hormone and depression.
Author quotes Ray Peat on thyroid adaptation to stress, chronic depression under prolonged stress, and progressive thyroid decline with aging unless supported with appropriate intervention.
Quoting Ray Peat, the post says low thyroid impairs sugar storage, so the body burns down slowly without efficient repair, and the goal is to stop decay and begin repair.
Quoting Ray Peat, the post claims hospital patients with the same diseases but lower body temperature are less likely to survive. It says low thyroid, an adaptation to stress, eventually stops being protective and interferes with healing, leaving people living on adrenaline and cortisol that destroy tissues.
Quoting Ray Peat, the post claims he has seen low-thyroid people make 30-40 times normal adrenaline, which leads to cortisol production. It says this adaptation can feel like being on speed and confuses doctors and patients.
Quoting Ray Peat, the post says adrenaline and cortisol normally rise at night as a fasting state, but are higher with low thyroid or old age, making nights more stressful and insomnia more common.
Quoting Ray Peat, the post says early waking after 5-6 hours is common in older people and in young people with low thyroid. It claims extremes can cause hyperactivity, poor attention, irritability and depression, which disappear when thyroid and blood sugar are normalized and cortisol and adrenaline come under control.
Quoting Ray Peat, the post challenges the stereotype that low-thyroid people are lethargic. It claims many become hyperactive from high adrenaline compensating for low blood sugar.
Lowmegatron says that by 'thyroid' Ray Peat meant more than TSH or gland activity. He claims stress lowers T4-to-T3 conversion and T3 activity, which may not show on thyroid blood tests.
Quote of Ray Peat explaining that low thyroid people may become hyperactive due to high adrenaline compensating for low blood sugar, and that chronic stress causes thyroid depression with age.

Describes arthritic pain as overlooked symptom of low thyroid hormone availability. Cites research on thyroid involvement in rheumatological disorders, presents detailed case of hypothyroidism presenting as destructive arthropathy reversed by levothyroxine, describes rheumatic manifestations in children responsive to thyroid replacement, and includes Ray Peat anecdote about rapid arthritis resolution with thyroid treatment.
10-week RCT of 70 children with autism comparing risperidone alone vs risperidone plus PEA (palmitoylethanolamide); PEA group showed greater improvement in irritability (46% vs 31%) and hyperactivity (27% vs 11%); PEA action attributed to glutamate/neuroinflammation reduction and suspected mast cell stabilization.
Bulleted list of dietary and lifestyle interventions for optimizing thyroid hormone conversion, including carbohydrate intake, stress management, micronutrient adequacy, avoiding mold/fluoride, and T3/T4 hormone balance considerations.
Mold exposure induces stress and lowers thyroid hormone conversion causing hypothyroid symptoms despite normal thyroid gland; case series of 4 patients unable to work on levothyroxine (T4) alone who recovered when T3 was added and returned to mold-free buildings; mechanism attributed to non-thyroidal illness syndrome (NTIS).
Hypoglycemia was a recognized symptom of hypothyroidism historically but omitted from modern textbooks; multiple sources (Broda Barnes, Ray Peat, clinical case reports, animal studies) document that thyroid hormones enable efficient glucose production and that hypothyroidism causes glucose waste leading to hypoglycemia.
Author reports plantar fasciitis as personal first indicator of low thyroid hormone, particularly noticeable at night; cites one paper associating elevated TSH and lower thyroid hormones with plantar fasciitis; references case series of hypothyroid children misdiagnosed with various rheumatic conditions who improved with thyroid replacement.
Ray Peat quoted explaining that stress (cortisol and adrenaline) can shift T4 metabolism toward reverse T3 formation; emphasizes selenium as crucial nutrient for T4 to T3 conversion across all tissues requiring seafood intake (~weekly).
Hypothyroid men have lower libido, lower sperm count, higher prolactin, and twice the prevalence of clinical hypogonadism (13.8% vs 6.5%); mechanism involves T3-mediated STAr protein expression in Leydig cells limiting cholesterol transport for testosterone synthesis; T3 addition to T4 therapy improves sexual desire in biochemically euthyroid men with persistent symptoms.
Ray Peat anecdote on muscle gain inability in hypothyroidism; notes low testosterone and high cortisol shift body composition from muscle to fat; mentions thyroid hormone excess also causes muscle wasting.
Coffee consumption study showing protective liver effects at ≥5 cups/day; embedded Ray Peat quote on proper coffee consumption technique using cream to slow caffeine absorption.
T3 thyroid hormone essential for body temperature maintenance; approximately 37-50% of energy expenditure in sedentary/normal humans dedicated to thermoregulation; body temperature useful indicator of thyroid status independent of blood tests.
Progesterone and thyroid supplementation resolved 4-year histamine intolerance in 3 days despite normal thyroid labs; progesterone inhibits mast cell degranulation; hypothyroidism increases mast cell population and histamine content; embedded quote links thyroid hormone to CO2 production and mast cell regulation.
Glycine from collagen/gelatin protects against endotoxin and reduces mortality in animals given lethal endotoxin doses; embedded Ray Peat quote describes glycine's broad protective antistress action across cell types.
Well-designed study comparing natural desiccated thyroid (NDT) to levothyroxine showed NDT superior with 2.5-6.5× lower symptom rates; NDT dosing based on symptoms and urinary free T3, not TSH; T3 is active hormone; levo has minimal biological activity; improvement averaged 69% compared to <25% placebo effect.
Thyroid hormone promotes liver regeneration after major injury; 70% hepatectomy in normal thyroid rats showed full recovery in 96 hours vs only 50% recovery in 4 days in hypothyroid rats; thyroid hormone restores regenerative capacity and mitochondrial function.
Author reports multiple anecdotes linking plantar fasciitis to low thyroid hormone; NDT treatment and increased carbohydrate intake resolved foot pain; embedded study shows higher TSH and lower T3/T4 in plantar fasciitis patients.
Selenium concentration is highest in the thyroid and deficiency is associated with hypothyroidism, subclinical hypothyroidism, Hashimoto's, Graves' disease, and thyroid cancer. Embedded quote attributes to lowmegatron that selenium is required for thyroid hormone conversion and calms autoimmune thyroid processes.
Hypothyroid men have lower libido, lower sperm count, and higher prolactin; they are twice as likely to have clinically low testosterone. T3 enhances testosterone biosynthesis via STAr protein expression in Leydig cells. Correcting hypothyroidism can double testosterone and halve prolactin. Subclinical hypothyroidism (TSH 4.5–10) also causes sexual dysfunction. Adding T3 to T4 therapy improves sexual desire.
Enterosgel, a polymethylsiloxane polyhydrate enterosorbent, may increase live births in women with endometritis when combined with antibiotics and probiotics. Endotoxin lowers progesterone and elevates PGF2α, increasing abortion risk; Enterosgel absorbs endotoxin. A study of 98 patients showed live birth rates of 6/32 with antibiotics alone, 19/33 with antibiotics plus Enterosgel, and 30/33 with antibiotics plus Enterosgel plus probiotic.
Pregnenolone may help reduce alcohol cravings and anxiety in alcohol use disorder. A Ray Peat anecdote describes an alcoholic man whose anxiety and depression lifted after taking pregnenolone, describing it as 'the feeling I've been trying to get from alcohol, but it never worked.' Alcohol's calming effects are mediated through pregnenolone, DHEA, allopregnanolone, and progesterone. A human study (2023) found pregnenolone (300–500 mg/day) reduces stress-induced and alcohol cue-induced craving and normalizes HPA axis function. Author recommends Balancedbodymind, Raena, and Forefront Health pregnenolone brands, cautioning that many brands produce bad effects.
Topical CO2 application accelerates bone healing and increases bone density in a rat femoral defect model. At 4 weeks, CO2-treated bones showed 4× higher healing rate (18% vs 72%), 12× greater ultimate stress, 6× greater extrinsic stiffness, 9× greater failure energy, and 37% higher volumetric bone mineral density (180 vs 248). CO2-infused water or SodaStream cylinders suggested as delivery methods. Embedded quote from lowmegatron references Ray Peat on vitamin K2 and aspirin for bone health.
Women injected with endotoxin show significantly less empathy for others' psychological pain compared to placebo controls. Endotoxin interferes with thyroid hormone and glucose metabolism; empathy is a high-energy state. Low-grade inflammation reduces empathy as an adaptive energy-conservation strategy. Embedded quote from lowmegatron describes endotoxin effects on mood and behavior, including aggression and anxiety in rats fed fermentable fibers.
Quotation from McGavack's clinical text states methimazole is the least toxic and most efficient antithyroid compound compared to iodine, propylthiouracil, and methylthiouracil. Embedded quote from lowmegatron describes iodine-induced hypothyroidism from habitual Povidone-iodine gargling and excessive kelp/kombu consumption, with case study of Japanese man whose TSH normalized when iodine sources were removed.
Quotation from McGavack's clinical text states that in thiamine deficiency, experimental animals show decreased ability of thyroid hormone to raise basal metabolic rate. Embedded quote from lowmegatron synthesizes Ray Peat statements on thyroid and thiamine for cognitive function, citing studies linking basal metabolic rate to IQ, thyroid hormone to intelligence, thiamine intake to cognitive performance, and a controlled trial of thiamine supplementation in orphans showing superior gains across 18 test tasks.
The Randle Cycle describes glucose-fatty acid competition regulated by hormones and enzymes, not macronutrient timing. Ray Peat recommended mixed meals with saturated fat and lower overall fat intake for fat loss, emphasizing baseline lipolysis control over macronutrient separation.
Saturated fat, particularly clarified butter, improves survival in severe alcoholic hepatitis and reduces alcoholic liver disease. Saturated fat is resistant to peroxidation unlike polyunsaturated fat, reducing inflammation, improving gut barrier function, and preventing thyroid hormone interference.
Humorous statement about teaching carrot-grating technique.
Poll asking followers to choose a favorite Ray Peat book among three titles.
Social observation about content reposting by Brazilian accounts.
Selenium is essential for tissue-level thyroid hormone T3 production. Consuming shellfish, seafood, halibut, cod, or sole provides sufficient selenium to maintain active tissue thyroid hormone supply.
Quoting Ray Peat, the post claims one seafood meal per week supplies enough selenium for tissues to form T3. It says that without selenium, tissues cannot make the T3 they need even if circulating T4 is adequate, because selenium is required for deiodinases.
Quoting (apparently Ray Peat; the attribution is not stated in this post), the post claims selenium is needed to activate the thyroid, that other B vitamins and nutrients are needed too, that low thyroid and low selenium are the most common problems, and that glucose is needed to use selenium for thyroid activation.
Quotes Ray Peat as saying that lacking selenium or vitamin D can leave T4 unconverted so it accumulates and interferes with T3, becoming antithyroid, and that he thinks 100 micrograms of selenium is a safe supplement. The quoted context is the author's own claim that selenium concentration is highest in the thyroid and that deficiency is associated with several thyroid conditions.
Humorous satirical quote attributed to Ray Peat about adding something to Twinkies.
High cortisol causally increases risk of obesity, insulin resistance, type 2 diabetes, insomnia, depression, fatty liver, low thyroid hormone T3, and high blood pressure. Post announces tips for cortisol management.
The author claims vitamin C lowers stress-induced cortisol release and cites two PMIDs: excess vitamin C inhibits cortisol secretion after ACTH, and vitamin C was used in women with functional hypercortisolemia or elevated DHEA-S. The author prefers food sources such as fruit, juice and acerola powder.
The author claims parathyroid hormone increases cortisol and that PTH is elevated with low dietary calcium and low vitamin D. Three PMID quotations on PTH stimulating cortisol secretion are given. The quoted context is an earlier post linking PTH to obesity and depression, citing Ray Peat and studies.
The author claims vitamin D appears to lower 11β-HSD1 activity, describing the enzyme as regenerating cortisol locally and implicated in insulin resistance, obesity, fatty liver and T2D. Cites a study where 2,000 IU for 2 weeks reduced cortisol and the cortisol:cortisone ratio versus placebo.
The author claims salicylate, an aspirin metabolite, lowers tissue cortisol regeneration by reducing 11β-HSD1. Quotes a paper reporting improved glucose tolerance in obese mice, reduced adipose 11β-HSD1 in men given salsalate, and this mechanism contributing to salicylates' metabolic effects.
The author claims aspirin itself lowers stress-induced increases in ACTH and cortisol, quoting a study that aspirin blunted ACTH and cortisol after exercise.
The author says drugs that reduce local cortisol via 11β-HSD1 inhibition are being investigated for T2D, quoting a paper that whole-body 11β-HSD1 activity is increased in obese men with T2D and inhibitors may work best in them.
The author claims coffee, which is associated with reduced T2D risk, contains 11β-HSD1 inhibitors that reduce local cortisol regeneration. Quotes a study showing espresso extract inhibited the enzyme and suggesting this explains part of coffee's antidiabetic effect.
The author claims DHEA may lower 11β-HSD1 and local cortisol generation, quoting a paper suggesting some antidiabetic DHEA effects come from inhibiting glucocorticoid amplification in adipose tissue. The author suggests low doses (no more than 5 mg, 3x a day) because higher doses can increase estrogen.
The author claims emodin (found in cascara sagrada, aloe, rhubarb) inhibits 11β-HSD1, reducing local cortisol, and in obese mice reduced insulin resistance, liver fat and high blood sugar. Mentions a supplement called Lapodin, stating they have not tried it and are not affiliated.
The author claims 250 mg each of magnesium and potassium lowered serum cortisol by nearly 50% in type 2 diabetes patients and greatly improved insomnia scores, with severe insomnia falling from 38% to 0%. Quotes a study finding significant effects on cortisol, melatonin and insomnia severity.
The author claims darkness increases cortisol and bright light reduces it after an initial spike, that low light keeps cortisol elevated, and that most indoor lighting is insufficient. Quotes a study finding lower cortisol under constant bright light versus dim light, but not with intermittent bright light.
The author claims creatine reduces stress-induced cortisol increases. Quotes a study suggesting more than 5 days of creatine with resistance exercise increased testosterone and decreased cortisol concentrations.
The author claims L-theanine lowers the cortisol response to stress. Quotes a double-blind, placebo-controlled crossover study where subjective stress fell at one hour and cortisol response at three hours; the active treatment also contained alpha GPC, phosphatidylserine and chamomile, not just theanine.
lowmegatron claims hypothyroidism raises cortisol and that hypothyroid symptoms resemble excess-cortisol symptoms. He cites a study (PMID 23111240) whose authors suggest TSH above 2.0 uIU/L may be abnormal because of its positive relationship with cortisol. He also says thyroid hormone regulates 11β-HSD2, which inactivates cortisol, so low T3 reduces cortisol detox, and that TSH is not a reliable measure of this.
lowmegatron says hypothyroidism activates the sympathetic nervous system, raising stress hormones, anxiety, blood sugar and blood pressure. He lists +60% cortisol and doubled adrenaline, noradrenaline and aldosterone, from a study of hypothyroid people who stopped their medication. He says diastolic blood pressure fell as T3 rose with replacement.
Thyroid hormone T3 accelerates response to tricyclic antidepressants, with stronger effect in women. Women experience higher rates of thyroid issues and thyroid hormone conversion problems, reducing available active T3. Meta-analysis of six studies found T3 significantly more effective than placebo, with effects stronger as female study participation increased.
lowmegatron notes liothyronine is the pharmaceutical name for T3. He claims over half of depressed patients respond to T3, citing a trial in which 10 of 17 responded to liothyronine, 9 of 17 to lithium and 3 of 16 to placebo as augmentation of tricyclic antidepressants in refractory unipolar depression.
lowmegatron says T3 reduces depression in people on the SSRI sertraline, with those who had lower baseline T3 improving more. He quotes a randomized trial reporting response rates of 70% versus 50% and remission of 58% versus 38% for sertraline plus liothyronine versus sertraline plus placebo.
lowmegatron says 25% of antidepressant-resistant patients responded to T3. He quotes a STAR*D report with remission of 15.9% on lithium and 24.7% on T3 augmentation, a difference not statistically significant, and notes lithium had more side effects and dropouts.
lowmegatron comments that T3 is not an antidepressant, but that many depression cases reflect low brain energy. He claims optimizing brain T3 normalizes ATP production and that TSH and T4 tests cannot reliably infer T3. He warns T3 is a metabolic stimulant that can be dangerous in excess, especially with heart issues. He also argues the standard 25 mcg+ once-daily research doses are suboptimal and that more physiological dosing would likely improve results.
The author cites a 2017 paper reporting higher TSH in women with unexplained infertility. He says TSH of 2.5-5.0 was twice as common in that group, and quotes McGavack's historical text linking subclinical hypothyroidism to miscarriage and its symptoms.

Historical pharmaceutical advertisement from 1951 that deceptively marketed phenobarbital to physicians under a trade name, omitting risks of respiratory depression, addiction, suicide, pulmonary edema, renal failure, and death.
T3 (active thyroid hormone) has been neglected in favor of T4 in thyroid research and treatment. Ray Peat distinguished low T3 activity from traditional hypothyroidism definition. Multiple causes beyond gland dysfunction can produce low T3 symptoms.
Light exposure affects thyroid hormone requirements seasonally. Absence of bright light creates progesterone deficiency, allowing unopposed estrogen and prolactin. Ray Peat observed seasonal health problems (premenstrual syndrome, arthritis, colitis) in students moving to cloudy Eugene and proposed reorganizing medicine around estrogen-related processes.

Historical case report documents cognitive and behavioral improvements in autistic child using high-dose T3 therapy under medical supervision. Embedded post describes elevated blood serotonin in autism and hypothyroidism-serotonin relationships.
Ray Peat quote: thyroid deficiency should be considered when digestive gas persists despite diet changes, as hypothyroidism causes low stomach acid and generalized digestive depression
lowmegatron says reduced motility is the central GI manifestation of hypothyroidism, with low stomach acid, delayed gastric emptying, constipation and SIBO. He proposes tissue waterlogging as a likely mechanism. He says levothyroxine monotherapy is more strongly associated with SIBO and offers possible reasons (inadequate T3, sicker patients, longer duration), which he suspects combine. He quotes a cohort finding that levothyroxine was a stronger predictor of SIBO than hypothyroidism.
lowmegatron says SIBO rates in hypothyroidism are 3 to 10x those of healthy people. He quotes a study in which 54% of hypothyroid patients had a positive breath test versus 5% of controls. He says correction usually needs T3 optimization and decontamination. The quoted parent post claims SIBO lowers vitamin K2 and matrix Gla-protein activation and so raises atherosclerosis risk.
Bioidentical progesterone acts as physiologic sleep regulator restoring normal sleep when disturbed, without inhibiting deep sleep like hypnotic drugs. Particularly beneficial for elderly. Embedded post describes thyroid hormone deficiency effects on sleep onset and duration.

Author lists interventions claimed to decrease chronically elevated cortisol, including light exposure, dietary fats, micronutrients, supplements, and lifestyle factors. Quoted source discusses mold-induced stress lowering thyroid hormone T3 conversion and successful T3 supplementation in four patients previously unresponsive to levothyroxine.
Author claims zinc supplementation improves insulin resistance, inflammation, and oxidative stress in type 2 diabetes, citing systematic review. Embedded quote from lowmegatron discusses high cortisol causally increasing diabetes and obesity risk.
Author claims hypothyroidism stimulates adrenal output and sympathetic nervous system, doubling adrenaline and noradrenaline and increasing cortisol by 60%, citing study on thyroid hormone role in blood pressure. Embedded quote from lowmegatron discusses forgotten hypoglycemia symptom of hypothyroidism, quoting Ray Peat, Broda Barnes, and citing multiple studies on thyroid-glucose metabolism.
Author quotes Ray Peat discussing crude vitamin E's stamina-increasing effect from long-chain saturated fats and waxy materials, later identified as policosanol, with discussion of Cuban research and historical suppression. Embedded quote discusses policosanol's upregulation of Klotho anti-aging protein in cancer cells.
lowmegatron quotes conclusions from a study of wheat germ oil with conditioning exercise in middle-aged men. It reportedly improved treadmill endurance, cardiovascular measures, reaction speed and lowered systolic blood pressure, and did not depress BMR the way vitamin E is known to, producing a slight rise instead.
lowmegatron quotes a double-blind trial in taekwondo athletes where policosanol reduced lipid peroxidation (MDA) and improved anaerobic performance, VO2max and Cooper test distance, with modest cardiometabolic effects. He explains VO2max and the Cooper test and says higher values mean improved endurance.
Author quotes clinical observation that patients with myofascial pain and mild hypothyroid-like symptoms refractory to standard therapies responded to mildly supraphysiological thyroid hormone dose. Embedded post attributes Ray Peat statement on hypothyroidism and parathyroid hormone as main causes of muscle knots, with clinical study citation.
Author reports aspirin reduces Candida biofilm and interrupts yeast metabolism through PGE2 reduction, mediated by linoleic and arachidonic acids from seed oils and conventional meats. Describes lab concentrations equivalent to 500-1,000 mg aspirin and lists risk groups.
Author quotes Ray Peat on organisms' responsiveness to weak electromagnetic signals from Earth's magnetic field and older research showing organisms govern metabolic rate by electromagnetic field changes, contrasting with current dogma attributing circadian effects to light-dark cycles alone.
Author claims pregnenolone synthesis from cholesterol depends on thyroid hormone, and hypothyroidism throttles this conversion, lowering sex hormones and increasing pain, depression, and anxiety. Cites study showing lower DHEA, DHEA-S, and pregnenolone sulfate in hypothyroid patients.
Hashimoto's patients with normal TSH experience fatigue and pain despite normal TSH levels. Levothyroxine monotherapy fails to optimize T3, whereas physiologic NDT or combined levo+liothyronine reduces residual symptoms. NDT dosed by symptoms rather than TSH shows substantially lower rates of constipation, headache, muscle cramps, depression, rheumatoid symptoms, cold intolerance, and fatigue compared to levothyroxine. Rheumatic manifestations of hypothyroidism in children resolve with thyroid replacement.
Autoimmune patients have lower zinc levels. Zinc deficiency causes thymic atrophy, impairing self-tolerance. Animal studies show zinc supplementation increases regulatory T cells and reduces Th17 cells in experimental autoimmune encephalomyelitis (mouse model of MS), suggesting zinc may induce immune tolerance in autoimmunity without immunosuppression.
Estrogen promotes Candida albicans virulence and growth by enabling immune evasion; progesterone reduces biofilm formation and virulence. Estrogen correlates with increased risk of vulvovaginal candidiasis during pregnancy, oral contraceptive use, and HRT. Progesterone lacks protective effect against infection in animal models but may reduce virulence determinants.
Pregnenolone increases deep sleep by converting to progesterone and allopregnanolone, exerting anti-cortisol and pro-GABA effects. Studies show pregnenolone increases slow-wave sleep, improves sleep efficiency, and reduces intermittent wakefulness. Progesterone restores normal sleep when disturbed without inhibiting deep sleep like hypnotic drugs. Achieving maximum plasma allopregnanolone requires 1,600 mg progesterone daily.
Ray Peat describes consuming 3,000-4,000 mg pregnenolone daily for a year while testing safety, observing only skin firming effects with no other side effects. A man in his sixties reportedly takes a teaspoon daily without adverse effects.
Studies show pregnenolone does not elevate downstream cortisol even at 500 mg/day for 8 weeks. Pregnenolone increases slow-wave sleep and suppresses EEG sigma power without altering sleep-associated nocturnal cortisol or growth hormone secretion. Pregnenolone metabolizes mainly to allopregnanolone and pregnenolone sulfate, not cortisol.
Personal anecdote: T3 (Cytomel) improved deep sleep onset, reduced 4am tachycardia and panic attacks. T3+T4 combination may improve slow-wave sleep compared to T4 alone, though uncertainty acknowledged. Citation describes decreased stages 3-4 sleep in untreated hypothyroidism. Embedded post promotes author's video course and online community on hypothyroidism understanding.
Ray Peat explains adrenaline compensation for low thyroid function dilates pupils. Levothyroxine works when liver has sufficient glucose and is not stressed by adrenaline. Combined T4+T3 formulations (Armour thyroid, Novotiral) superior to levothyroxine alone for stress hormone patterns. Cannabis interferes with liver function; recovery requires adequate protein and nutrients (orange juice, eggs, milk, cheese, cooked mushrooms, occasional shellfish).
Author explains that experimental hypothyroidism increases adrenaline (which raises heart rate) despite lower T3 normally decreasing heart rate, citing a study on sympathetic and adrenal activation in hypothyroidism.
Author explains magnesium bicarbonate water preparation and dosing, attributing the concern about magnesium supplements causing bowel inflammation to Ray Peat, and providing detailed instructions for making magnesium bicarbonate by reacting magnesium hydroxide with carbonated water.

Author reports chamomile tea lowered blood pressure from 150/95 to 120/80 in 2 hours via ACE inhibition, citing an experimental and clinical study on M. chamomilla antihypertensive activity with dosing and mechanism details.
Ray Peat warned about fluoride's effects on thyroid hormones in the 1970s. Fluoride lowers T3 and T4 and was historically used to treat hyperthyroidism. High intake is associated with hypothyroidism and in utero exposure with lower IQ. Taurine, calcium, and tamarind cited as protective compounds.
The author quotes a patient testimonial saying desiccated thyroid (NDT) resolved hair loss, fatigue and other symptoms after years on levothyroxine. He explains that NDT contains T3 and T4, claims people who fail on levothyroxine cannot make enough T3, and says synthetic T3/T4 combinations usually work as well as NDT when dosed properly.
Ray Peat discusses magnesium supplement-induced intestinal inflammation as cause of apparent belly fat increase. Explains mechanism involves histamine, nitric oxide, and endotoxin absorption. Notes water retention from inflammation occurs acutely, fat accumulation over months/years. Embedded quote details magnesium bicarbonate water preparation as alternative.
Experiment showing that paying attention to histamine skin reaction produces smaller inflammatory response and faster recovery than distracted control. 57 healthy volunteers underwent histamine prick test twice: once with attention, once distracted. Bump was roughly 1.5x smaller with attention; 90% showed this pattern. Mechanism involves vagal/interoceptive signaling rather than stress reduction.
Single markers in isolation—including basal temperature, heart rate, cholesterol, prolactin, TSH, thyroid hormones, and symptoms—cannot reliably diagnose hypothyroidism. Exception: low T3 is sufficient for diagnosis. Embedded quote references further detail.
Reddit user anecdote: hypothyroidism associated with skin darkening and loss of natural glow. Described progression from naturally glowing skin to muddy, dull, darker/tanned appearance with grey-brown tone, loss of translucency and brightness despite increased moisturizer use.
lowmegatron quotes a case report in which a woman with subclinical hypothyroidism (TSH 7.02, free T4 1.06) and hyperpigmentation improved after levothyroxine. He adds that estrogen is another possible cause and that any benefit from levothyroxine depends on conversion to T3. The quoted parent discusses thyroid antibodies, estrogen and melasma.
Mucopolysaccharides accumulate in tissue when T3 is low, causing tissue bloating and edema in hypothyroidism. Symptoms include nasal congestion, voice changes, carpal tunnel, joint issues. Shows before/after photos of women treated with NDT (which contains both T3 and T4), contrasting with levothyroxine (T4 only). Embedded quote promotes NDT video course and community.
PEA (palmitoylethanolamide) helps high histamine conditions by stabilizing mast cells and inhibiting histamine release. Natural fatty-acid amide produced in human tissues; modulates immune function. Must use micronized or ultramicronized forms. Multiple animal and human studies cited showing mast cell stabilization, reduced inflammatory mediators (PG D2, TNF-α, histamine), and symptom reduction.

Ray Peat quoted on adaptive eating: follow cravings as indicators of nutritional needs; body uses biological mechanisms to correct deficiencies. When sugar metabolism is impaired, carbohydrate craving prevents protein wastage.
Critique of low-calorie, low-carbohydrate diet recommendations for hypothyroid patients: caloric restriction and low carbohydrate intake impair T4-to-T3 conversion, worsening hypothyroidism while requiring progressive caloric reduction. Five peer-reviewed studies cited showing calorie and carbohydrate effects on thyroid hormone metabolism.
Pregnenolone mechanism for reducing alcohol drinking in animals and stress-induced alcohol craving in humans: increases allopregnanolone (GABA modulator). Mechanism depends on T3 and cholesterol. Recommends three specific brands with sourcing caution due to impurity risks.
Fruit and honey as evolutionary drivers of human brain size: anatomical and genetic evidence suggests early hominin diet was high in carbohydrates; modern human brain uses 66% of basal metabolic rate at age 5, fueled primarily by glucose.

Magnesium supplementation increases slow wave sleep, delta power, and sigma power while decreasing cortisol in older adults; dose escalation from 240-720 mg daily in 60-80 year old subjects.
Ginger and vitamin B1 (thiamine) improve specific hypothyroid symptoms; ginger reduces TSH and improves multiple symptom domains at 500 mg twice daily; thiamine 600 mg daily reduces fatigue in Hashimoto's patients, with treatment claims of partial/complete regression within hours to days.
Ray Peat quoted on ethanol as antioxidant; embedded quote from World_All_Alive reports personal anecdotal use of small vodka doses for self-reported histamine issues.
Pregnenolone downregulates endotoxin-related inflammation through degradation of TIRAP, TLR2, and TLR4 signaling; allopregnanolone (downstream metabolite) shows similar effects in cell culture and animal brain models related to multiple conditions.
Web searches and TSH levels show seasonal pattern in Hashimoto's thyroiditis; Ray Peat discusses light exposure and unsaturated fat restriction as winter management; thyroid function increases seasonally, suggesting light and fat composition affect thyroid metabolism.
Red light (670 nm) reduces postprandial blood glucose 27.7% and increases respiratory CO2, indicating increased glucose oxidation without lowering absolute glucose; blue light acutely alters glucose metabolism; light wavelength affects mitochondrial function and glucose utilization.
Glucose metabolism is reduced in ADHD-related brain regions; hypothyroidism and thyroid hormone resistance impair brain glucose metabolism; TSH within normal range but elevated correlates with ADHD symptoms and reduced cognitive function in preschoolers; thyroid hormone supplementation restores glucose metabolism in brain regions affected by hypothyroidism.

Embedded post on thyroid hormone and vitamin D effects on mast cell activation, including Ray Peat quotation and study citations on TSH, parathyroid hormone, and mast cell degranulation.
H. pylori lowers stomach acid impairing levothyroxine absorption; eradication lowers TSH and increases thyroid hormone levels, sometimes excessively. High TSH on high levothyroxine doses may indicate H. pylori or malabsorption. Embedded post on vitamin C's role in H. pylori prevention and treatment efficacy.
Comprehensive safety review of prescribed T3 (liothyronine) finding no risk from proper medical use; meta-analysis shows 30% lower mortality with T3 vs. T4. Side effects only reported in unsupervised use or pharmacy errors. No increased risk of atrial fibrillation, heart failure, or stroke. Cites systematic review study; notes T3 safety requires proper dosing and monitoring.
TRH increases blood pressure, resting pulse, and prolactin, which can lower testosterone and progesterone. TRH rises when thyroid hormones are low and stimulates TSH. When the thyroid does not adequately respond, TRH remains elevated. The embedded quoted post describes a patient's experience with T3 supplementation improving sleep quality and reducing nocturnal symptoms.
Gallbladder dysfunction is common in hypothyroidism due to delayed bile emptying, which can promote gallstone formation. Hypothyroidism is associated with an increased prevalence of common bile duct stones, with a gender-specific relation in males (TSH/gallstone correlation). The embedded quoted post discusses vitamin C's protective effect against gallstones through enhanced cholesterol-to-bile-acid conversion.

Discusses animal foraging behavior where apes and chimpanzees extract nutrients from fibrous plant material (pith) by chewing and sucking without ingesting the fiber, a behavior called wadging. Speculates whether this behavior could be replicated with mechanical juicing.
Presents the 'brain hypothyroidism' hypothesis that depression and hypothyroidism share clinical features and that low thyroid hormone may cause depression through reduced brain energy. The embedded quoted post introduces a thread on thyroid system's role in depression.
Discusses how TSH of 4 may not indicate optimal thyroid hormone status, particularly T3. Levothyroxine monotherapy suppresses TSH while reducing T3 bioavailability in peripheral tissues. Natural desiccated thyroid (NDT) increases available T3 and reduces anxiety. Low T3 hyperactivates adrenals and increases adrenaline/noradrenaline, contributing to anxiety. T3 optimization (not just TSH optimization) is needed; high T3 also causes anxiety.
Thyroid hormone is the primary driver of metamorphosis. Blocking thyroid function halts metamorphosis while feeding and growth continue, resulting in giant infantile tadpoles. Excess thyroid hormone produces miniature frogs. Historical and experimental evidence from tadpole studies demonstrates this relationship.
Fasting lowers thyroid hormone (T3) while also lowering TSH, causing a differential response in thyroid axis. Standard testing with only T4 and TSH during fasting/calorie restriction gives incorrect clinical impression because T3 conversion drops and TSH/T3 relationship reverses from the assumed pattern. Meta-analysis of 15 studies shows significant reductions in FT3 and total T3, moderate TSH decrease, and no significant FT4 change during fasting.
Correcting hypothyroidism and basal metabolic rate allows patients to tolerate alcohol without ill effects. Dr. Broda Barnes observed that hypothyroid patients unable to drink alcohol due to poor tolerance and hangover could drink freely once thyroid function was corrected. The embedded quoted post discusses pregnenolone's effects on alcohol cravings, stress, and HPA axis in individuals with alcohol use disorder.
The brain is a metabolically expensive organ representing 20% of basal metabolic rate despite being only 2% of body weight, fueled primarily by glucose. Humans can synthesize glucose from gluconeogenic amino acids but the process is inefficient and limited. The embedded quoted post reports that people who eat breakfast less than once weekly had approximately 200% higher odds of developing depressive symptoms over 3 years compared to daily breakfast eaters.
Individual differences in alcohol response depend on thyroid activity; alcohol has antioxidant effects but can cause hypoglycemia and pro-oxidative effects. Polyunsaturated fat (PUFA) increases alcohol's oxidative damage through iron-fat reactions. Saturated fat (clarified butter/MCT) reverses alcoholic liver injury better than unsaturated fat through reduced lipid peroxidation and gut barrier tightening. Saturated fat is not peroxidizable and reduces PUFA peroxidation. Thyroid hormone aids liver regeneration.
Author presents study findings on TSH vs T3 dynamics in levothyroxine-treated hypothyroid patients, arguing TSH normalization does not reliably indicate T3 normalization, and that routine T3 measurement should be considered despite clinical guideline omissions.

Author explains metabolic consequences of sleep restriction: elevated free fatty acids compete with glucose oxidation via Randle cycle, impairing insulin signaling and increasing type 2 diabetes risk.
Author presents evidence that thyroid hormone suppresses sympathetic nervous system activity; deficient thyroid causes compensatory adrenaline and noradrenaline elevation, contributing to hypertension.
Author argues depression is a state of low brain energy caused by insufficient T3, not diagnosis stress; low T3 impairs glucose oxidation, and T3 augmentation of SSRIs shows antidepressant effects correlated with brain bioenergetic normalization.
Thyroid hormone accelerates alcohol detoxification and affects neurosteroid production (pregnenolone, DHEA, progesterone, allopregnanolone), which mediate anxiety relief and intoxication effects. Hyperthyroidism markedly increases ethanol metabolism rate.
Sleep restriction to 6 hours or less impairs insulin sensitivity independent of weight changes in healthy subjects. Effects vary by sleep architecture component; duration, quality and circadian timing all affect insulin sensitivity and diabetes risk.
Thyroid hormone and thiamine improve memory and cognition by enhancing glucose utilization in the brain. Emotional arousal also increases glucose availability via stress hormones. Relationship breaks down in diabetes/insulin resistance where high blood glucose correlates with lower glucose oxidation.
Magnesium supplementation (240-720 mg elemental daily) significantly improves sleep parameters in older adults: 63% increase in slow wave sleep, 24% increases in delta and sigma power, 29% decrease in cortisol. Ray Peat noted magnesium carbonate few hundred milligrams daily improves sleep.
Thyroid hormone, particularly T3, is a primary regulator of blood cholesterol. Elevated cholesterol often indicates hypothyroidism. T3 therapy produces greater cholesterol reduction (13% LDL, 11% total cholesterol, 18% apolipoprotein B) compared to T4 alone at equivalent TSH suppression, and also reduces body weight via increased metabolic rate.
Skipping breakfast impairs metabolic flexibility, increases postprandial insulin and glucose, reduces insulin sensitivity, and increases fasting cholesterol. Effects persist throughout the day. Breakfast consumption improves postprandial glucose regulation, particularly in type 2 diabetes.
Magnesium intake is extremely low; less than one-third of heart attack survivors meet RDA. Higher magnesium intake associated with decreased cardiovascular death risk over the following decade. Magnesium functions as cellular calcium blocker regulated by ATP and thyroid hormone.

Thyroid hormones regulate ferritin synthesis independent of iron stores; thyroid status affects multiple iron-related biomarkers including ferritin, hemoglobin, transferrin, and TIBC. Reticulocyte hemoglobin may help distinguish thyroid-driven ferritin changes from iron deficiency.
Iron destroys vitamin E in animal feed and caused female rat infertility; wheat germ oil (vitamin E source) reversed iron-induced sterility. Author attributes Ray Peat quote and includes embedded discussion of policosanols and crude vitamin E historical research.
lowmegatron tags @BioavailableNd, saying they may be interested in this. The post makes no substantive claim. The parent is about iron destroying vitamin E and infertility, but this post does not say so.
Anemia has multiple causes; hemolytic anemia from vitamin E deficiency is common in premature infants and responsive to vitamin E treatment. Iron supplementation alone may worsen hemolytic anemia if vitamin E deficiency is present because iron destroys vitamin E.
Commercial laboratory animal diets in 1940s caused sudden neurogenic disease (tremors, forced movements, head retraction, weakness) in chicks due to iron salts destroying added vitamin E. Vitamin E supplementation (0.2mg alpha-tocopherol daily) prevented disease.
Thyroid hormone increases ferritin by releasing the brake on ferritin synthesis; ferritin falls when thyroid hormone drops.
Historical overview of Bonghan Kim's 1960s discovery of a third vascular system (now called Primo Vascular System/PVS) with DNA-containing particles proposed as repair mechanism. Kim's work was ignored; rediscovery and validation begun in 2002 by Kwang-Sup Soh. Recent research suggests PVS may relate to acupuncture meridians and body homeostasis. Embedded quote discusses Chinese glymphatic surgery for Alzheimer's (context only).
Short sleep (1.5 hours below habitual for 6 weeks) lowered TSH in women without changing FT4. Embedded quote discusses effects of 6-hour sleep on insulin sensitivity and sleep deprivation effects across multiple studies, with review of sleep's role in metabolic health.
Patient medical notes from 12–13 year levothyroxine user who switched to NDT 120 mg and reported resolution of dry skin, constipation, brain fog, fatigue, cold intolerance, and pain. Post explains NDT contains both T4 and T3 while levothyroxine is T4 only; NDT is prescription with standardized hormone levels, unlike unregulated over-the-counter products.
Post recount of discussion in which people report psychiatric misdiagnoses caused by undiagnosed hypothyroidism. Includes example of one doctor who refused psychiatric drugs when patient's thyroid hormones were abnormal. Quote: hypothyroidism caused depression resolved by thyroid medication without antidepressants.
lowmegatron quotes two people in a discussion. One says they were misdiagnosed as bipolar and given strong prescriptions that left them "zombie like". The other says a psychiatrist gave them Wellbutrin for 28 years.
lowmegatron quotes a person who says thyroid meds helped many things because the thyroid affects every body system, and that they were thrilled to stop anti-depressants.
lowmegatron quotes a person who was not diagnosed but says they fit the criteria for depression when hypothyroid, describing a shut-off brain and loss of personality, critical thinking and creativity.
lowmegatron quotes a person whose thyroid failed in their late teens. They say they were repeatedly diagnosed with depression and with being fat. At 22, testing revealed congenital thyroid hypoplasia and Hashimoto's. They mention milk production continuing long after nursing stopped.
lowmegatron quotes a person who says the first doctor told them they were bipolar, but it was Hashimoto's.
lowmegatron quotes a person who was told they had anxiety/depression. They say they got off Lexapro safely once thyroid meds kicked in, and that their panic is much reduced.
lowmegatron quotes a person who says they once had a TSH of 68 and an endocrinologist noted them as unstable and anxious. Another doctor insisted on SSRIs, which they declined.
Thyroid hormones play roles in anxiety, depression, and psychosis, yet psychiatric patients often lack thyroid testing. Post discusses case with multiple psychiatrists prescribing psychiatric drugs without thyroid screening. Notes Cymbalta lowers T4 by average 20%; 42% of patients had ≥30% T4 drop; TSH-only screening would miss this effect. Cites postpartum psychosis link to autoimmune thyroid disease (nearly 4× higher, 3× higher clinical dysfunction).
Ray Peat quote: Thyroid tends to lower cholesterol by converting it into pregnenolone and other steroids. Embedded quote discusses pregnenolone's effects on skin aging and health; Ray Peat personal account of pregnenolone's dramatic symptom relief from inflammatory conditions and associated facial rejuvenation.
Coffee increases T2 (thyroid hormone metabolite) with pro-metabolic effects. Animal studies show T2 reverses liver damage and insulin resistance. Human study finds T2 levels associated with coffee metabolites, suggesting coffee naturally increases T2. Author cautions that T2 reduces thyroid hormones via pituitary feedback; high doses unclear if safe due to T3 suppression and potential cardiac hypertrophy in animals.
Dietary and supplemental creatine is associated with lower depression risk in women; creatine augmentation of SSRIs and CBT shows faster and greater improvement in depression scores; creatine supports brain energy production and recovery from traumatic brain injury.
Levothyroxine monotherapy maintains normal TSH but produces elevated T4:T3 ratio, potentially leaving metabolic impairment unaddressed; combined T4/T3 therapy or desiccated thyroid produce higher T3 and lower T4 ratios. Embedded quote describes personal experience switching from levothyroxine to NDT with symptom improvement.
Hospitalized heart failure patients with low T3 have higher mortality; two trials show T3 supplementation improves cardiac performance metrics including stroke volume, ejection fraction, and walking distance while lowering cardiac stress markers. Embedded quote discusses thyroid hormone control of cardiac function and stress-induced suppression of T3.
Milk reduces lead absorption by up to 80%, primarily through calcium content, potentially reducing bioavailability of ingested lead particularly in individuals with low dietary calcium.
lowmegatron explains that 203Pb is a short-lived gamma-emitting radioactive lead isotope used to trace lead absorption in humans at very low radiation dose. The post says 580 g of cows milk was taken with the lead, and cites a study on calcium and phosphorus effects on gastrointestinal 203Pb absorption. A quoted earlier post promotes eggshell powder as a calcium source.

Hypothyroidism increases parathyroid hormone, which can lead to histamine issues, bone issues, and atherosclerotic calcification. Low calcium, magnesium, and vitamin D elevate PTH; vitamin K2 and higher calcium-to-phosphate ratio help prevent soft tissue calcification. Embedded post discusses thyroid hormone, vitamin D, and mast cell activation mechanisms.
Author quotes Ray Peat on factors supporting healthier pregnancies and postpartum outcomes, including sunlight, vitamin D, whole foods, thyroid function optimization, and specific hormones and anti-inflammatory medications.
Carbohydrate consumption during weight training blunts cortisol response, leading to greater muscle fiber growth. A 6% carbohydrate solution reduced cortisol spike by 93% versus placebo, and type I and type II muscle fiber area gains were significantly greater with carbohydrate ingestion. Cortisol response variance accounted for majority of muscle growth variance.
Weight loss resistance occurs when extreme calorie deficit suppresses thyroid hormone conversion and resting metabolic rate. Low energy availability abruptly reduces T3 and fT3, and increases fT4 and rT3 at specific thresholds. Increasing energy availability restores thyroid function and can reverse athletic amenorrhea without reducing exercise. Embedded post by lowmegatron discusses thyroid hormone's role in insulin sensitivity and depression.
Author suggests investigating 'irrelevant biomarker hacking' with no further context or explanation provided.
Bioidentical progesterone reduces anxiety and increases pro-social and exploratory behaviors in mice via increased allopregnanolone (5α-reductase metabolite); synthetic progestin (MPA) does not produce this effect because it does not serve as substrate for 5α-reductase. Neurosteroid effects may be relevant to sex differences in neuropsychiatric and neurodegenerative disorders. Embedded post discusses thyroid hormone's role in alcohol detoxification and neurosteroid production.
Ray Peat quote and embedded post on allopregnanolone as downstream mechanism of progesterone's mood, seizure and psychosis effects; pregnenolone supplementation (400 mg) proposed to increase allopregnanolone and activate emotion regulation circuits; specific supplement brands mentioned without claimed affiliation.
Caffeine coffee (not decaf) reduces chronic unpredictable stress effects in mice, limiting anxiety, anhedonia, helplessness and weight gain; speculated mechanism via adenosine A2A receptor antagonism.
lowmegatron lists claimed antidepressant actions of coffee: boosting dopamine, increasing energy, reducing prolactin, lowering inflammation, and lowering endotoxin while strengthening the gut barrier. The quoted post describes a small study of 20 healthy women where coffee was followed by lower blood sugar and cortisol.
Partial quote from historical document ('Next time I shall write more and in greater detail; incidentally, the cocaine brush has been completely put aside'); embedded post contains critical comment on coffee as escape drug for those lacking inner mental work.
Hypothyroidism alters muscle protein synthesis and breakdown, shifts fiber type, increases catabolic hormones causing muscle weakness and loss; unchanged muscle mass may contain excess water.
Coffee drinkers have lower TSH and much lower risk of subclinical hypothyroidism; embedded post attributes extensive caffeine and coffee health benefits to Ray Peat, including thyroid protection, liver protection, cancer prevention, and cognitive effects.
TSH within normal reference range associated with significantly increased odds of miscarriage; study citation provided.
lowmegatron quotes a study's statement that higher TSH was associated with early-pregnancy miscarriage. It says TSH of 2.5 to 4.8 raised risk, and above 4.8 raised it further.
lowmegatron says the role of subclinical hypothyroidism in habitual abortion was known in the 1920s, quoting a passage that cites Litzenberg (1926) and stresses recognizing and treating it.
lowmegatron quotes McGavack's The Thyroid, saying thyroid underfunction commonly shows as weight gain, lassitude, dry skin, coarse hair, brittle nails and emotional unrest. The quote states habitual abortion is frequent in such patients, citing Delfs and Jones (1948). It continues a thread on TSH and miscarriage.
lowmegatron states that eyebrows can regrow once thyroid hormone levels are corrected. He quotes a paper saying normal telogen-anagen hair relationships were restored with desiccated thyroid replacement, implying thyroid hormone affects hair growth initiation and duration.
Hypothyroidism causes nasal congestion through mucous gland enlargement and tissue edema. Quoted account (lowmegatron) explains the mechanism: T3 is required to break down mucopolysaccharides; when T3 is low, these accumulate causing tissue swelling, nasal congestion, voice changes, carpal tunnel syndrome, and joint issues. NDT USP (desiccated thyroid containing T3) differs from levothyroxine (T4 only).
Creatine may help some migraine sufferers. Thalamic creatine is low in people with migraine, reducing energy reserve in the region that gates pain signaling. Research shows creatine improves traumatic headache but not migraine specifically. Many internet reports describe migraine improvement with creatine. Embedded quoted account discusses hypoglycemia as migraine trigger and cites Ray Peat on liver function and treatment with fruit juice.
Broda Barnes' method of assessing thyroid status via basal temperature, symptoms, and response to desiccated thyroid accounts for hormone conversion and resistance in ways levothyroxine plus blood tests cannot. These markers often reveal insufficient thyroid hormone activity better than blood tests, though blood tests should not be ignored. Distinguishes between thyroid gland function and thyroid hormone status.
Lower basal body temperature in hypothyroid patients allows pathogens to take hold. Nasal cavity temperature is lower, enabling cold and flu onset there. Low temperature enhances viral viability and transmission (especially influenza); rhinovirus replicates preferentially at nasal cavity temperature due to less efficient antiviral response at cool temperatures. Temperature of 36.7°C restricts fungal growth. Embedded quoted account cites Broda Barnes on hypothyroidism and immunity in baby rabbits.
Aloe vera juice lowers thyroid antibodies (TPOAb) but also lowers free T3 and increases FT4:FT3 ratio, suggesting reduced thyroid hormone conversion. Very limited human data; one case report of a woman with low thyroid hormones (T3 and T4) that normalized upon stopping aloe vera juice, and a thyroid nodule that shrank when discontinued. Recommendation: monitor free thyroid hormones closely if using aloe vera juice. Embedded quoted account provides tips for optimizing thyroid hormone conversion.
Hypothyroidism lowers pregnenolone and downstream steroid hormones (DHEA, testosterone, estrogen) with implications for mood, mental illness, reproduction, libido, dementia risk, substance abuse, aging, appearance, and muscle mass. StAR protein shuttles cholesterol into mitochondria to make pregnenolone; thyroid hormone T3 regulates StAR. Study shows serum ADIOLS, ADIOL, DHEAS, DHEA, and pregnenolone sulfate are decreased in hypothyroidism. Embedded quoted account lists hormones derived from pregnenolone.
With hypothyroidism, the 'calories in calories out' model must account for T3 effects on resting metabolism. Lower T3 activity reduces 'calories out' (metabolic rate). Insufficient available calories further reduces T4 to T3 conversion. Before applying CICO model, verify T3 optimization via blood test and confirm T3 reaches cells via basal temperature. Embedded quoted account details how severe caloric restriction causes drops in T3 and metabolic adaptation; T3 repletion reverses hypometabolism and restores metabolic rate.
Glycine 3g twice daily (equivalent to 1 oz gelatin) may reduce nocturia and related bladder symptoms. Rodent studies show reduced bladder contractions; human evidence cited for nocturia, urgency, incontinence, bladder pain and blood pressure reduction. Some individuals may experience paradoxical reaction requiring dose testing.
Emodin, found in plants like Japanese knotweed root and rhubarb root, lowered thyroid autoimmune markers (TGAb antibodies) and reduced thyroid infiltration in iodine-sensitive mice, increasing T4. Embedded quote notes emodin also inhibits 11β-HSD1 enzyme, reducing local cortisol and improving metabolic markers in obese mice; available as supplement Lapodin (author claims no affiliation).
Hypothyroidism increases homocysteine; thyroid hormone replacement lowers it. While most homocysteine-lowering interventions show minimal cardiovascular benefit, Broda Barnes' thyroid therapy method reportedly achieved significant heart attack and stroke reductions. Both Barnes and Kountz cautioned against initiating therapy at high doses in cardiac patients.
Hypothyroidism leads to estrogen dominance partly through suppressed progesterone and pregnenolone. Thyroidectomy in animals causes progesterone and pregnenolone levels to drop due to reduced mitochondrial respiration needed for pregnenolone synthesis. Deficiency of active T3 thyroid hormone is the mechanism. Low basal temperature may indicate low T3 despite normal thyroid blood markers.
Brief factual statement that male contraceptive pill works by partially blocking vitamin A effects, with human trials ongoing.
Women's menstrual cycles historically synchronized with lunar phases but have decoupled since 2010 following LED adoption. Study finds cycles before LED adoption (pre-2010) synchronized with moon; post-2010 cycles mostly desynchronized except in January (month of strongest Moon-Sun-Earth gravitational forces). Raises question of LED light spectrum effects on female cycle regulation.
Carbonated water reduces fatigue and increases enjoyment during prolonged esports play. Study found sparkling water suppressed subjective and cognitive fatigue, likely through enhanced prefrontal cortex activity (measured by attenuated pupil diameter reduction). Embedded post notes 250 ml carbonated water increases satiety and reduces hunger through CO2-induced oral stimulation and altered gastric contractions.
Broda Barnes' claim that 40% of population is hypothyroid cannot be supported by standard definition (thyroid gland failure to release sufficient hormone) or current blood testing. However, since hypothyroid symptoms primarily result from insufficient thyroid hormone stimulation in cells and tissues, standard blood levels and gland function represent only part of the clinical picture.
lowmegatron says low thyroid hormone activity with a healthy gland and normal blood tests can stem from poor cellular uptake, conversion problems, or thyroid hormone resistance. He notes Mark Starr's term "type II hypothyroidism" and says the percent affected is hard to determine.
lowmegatron says Barnes treated patients with NDT, which he says gets around many conversion issues because it contains some T3. He says Barnes diagnosed based on basal temperature, signs and symptoms, and response to an NDT trial. The author claims basal temperature reflects cellular thyroid hormone activity and can reveal what blood tests miss.
lowmegatron says that in the 1930s G. K. Wharton reported improvements in a long list of symptoms (migraine, menstrual irregularities, dry skin and hair, acne, fatigue, low libido and others) in cases of hypothyroidism that the standards of the day did not recognize. The parent posts discuss Barnes, NDT and basal temperature, but this post does not itself mention them.
Thyroid hormones and TSH fluctuate throughout the day with circadian rhythm; testing at consistent times improves result reliability. FT3 shows delayed circadian rhythm parallel to TSH, suggesting thyroid-derived T3 contribution.
Glycine from gelatin or collagen provides system-wide benefits; Ray Peat recommended 2 ounces daily from meat cuts or supplemental gelatin. Author describes personal preparation method. Embedded quote attributes type 2 diabetes improvements (HbA1c reduction) to glycine supplementation with caveat about individual sensitivity.
Humorous reference to Joe Rogan deadpan claiming Alexa is conscious and can remote view.
Caloric restriction and fasting reduce tissue uptake of thyroid hormones, with T4 transport more affected than T3. This tissue-level effect may underestimate problems during stress. Embedded quote expands on multiple causes of tissue-level hypothyroidism beyond blood tests.
TSH shows pronounced circadian rhythm: highest at 7am, lowest at 1pm (women) or 2pm (men), then rises at 4pm. Same patient can appear normal or hyperthyroid depending on sampling time. Embedded quote critiques blood-based thyroid testing and contrasts with historical symptom-based diagnosis methods.
Skin-to-skin contact halves cortisol in NICU preterm infants while increasing melatonin, providing strong evidence that contact ameliorates NICU-related stress. Embedded quote from Ray Peat on healthier pregnancy factors including sunlight, nutrition, thyroid optimization, and hormonal support.

Critical examination of Ray Peat's work showing his nuanced understanding of hormones and biochemistry, criticizing how his ideas are oversimplified and memefied on social media. Peat understood cortisol, histamine, and serotonin's regulatory roles but critiqued pharmaceutical marketing narratives, particularly serotonin as 'happiness hormone.'
Thyroid extract historically used for migraine; high estrogen associated with migraine. Broda Barnes found low basal temperature in migraineurs; NDT or combination thyroid therapy corrected temperature and resolved migraines in most cases. Thyroid and sex hormone irregularities do not account for all migraine causes.
Miniature rose extract reverses IBD in rodents via gut microbiota regulation, intestinal barrier restoration, inflammatory protein inhibition, and metabolic dysregulation correction. TCM uses this Chinese plant for gut issues.
Vitamin C improves levothyroxine absorption, lowers TSH, and improves quality of life in hypothyroid patients requiring high-dose levothyroxine, per proof-of-concept pilot study.
Artificial sweeteners from anti-sugar messaging may cause thyroid issues; aspartame alters pituitary-thyroid axis and disrupts thyroid follicular structure, reducing hormone production; sucralose downregulates thyroid axis in rodents, lowering TPO enzyme, TSH, and T3/T4.
lowmegatron quotes a case report of a 52-year-old woman whose Hashimoto's was attributed to excessive non-nutritive sweetener beverages. The quote says TSH and antibody levels quickly normalized after she stopped the sweeteners.
lowmegatron quotes a rat study, 'Type of sweet flavour carrier affects thyroid axis activity in male rats'. It reports that, compared with sucrose, sucralose lowered TPO activity, T4 and T3. In the non-sweet diet, DIO1 was lowest and rT3 highest, indicating altered peripheral thyroid hormone metabolism.
Cocoa lowers inflammation by improving gut barrier function and reducing endotoxin burden; cocoa extract supplementation decreases hsCRP and is associated with cardiovascular benefits.

Low potassium causes leaky gut and increases endotoxin absorption through impaired intestinal epithelial barrier; author cites research on hypokalemia in critical illness and chronic disease.
Some keratin overgrowth diseases are caused by vitamin A deficiency and can be corrected with early treatment; author attributes quote to Ray Peat explaining keratin formation mechanism.
lowmegatron quotes a study of 59 patients with conjunctival xerosis, with or without Bitot's spots. Of these, 50 responded to vitamin A and nine did not. The quote says bilateral Bitot's spots, or spots with night blindness, suggest active vitamin A deficiency in preschool children. Some nonresponsive cases were probably sequelae of past deficiency.
Night blindness can signal thyroid hormone insufficiency; thyroid hormone resistance reduces electrical signal in light-sensing rods; strong natural light triggers thyroid hormone conversion in the eye.
Laughter-inducing interventions may improve health outcomes in patients with somatic or mental health problems through improved mood, well-being, or reduced anxiety, depression, stress, pain, and fatigue; 45 studies reviewed with largely positive outcomes and rare adverse events.

Ray Peat and Ivor H. Mills (Professor of Medicine, Cambridge) both documented individuals with metabolic efficiency who maintain body weight on very low calorie intakes (600-700 kcal/day), and conversely some with high metabolic rates who fail to gain weight on 3500 kcal/day. Effect attributed to thyroid hormone influence on metabolism.
lowmegatron quotes Ray Peat saying that doctors followed a textbook claim that anyone loses weight below 1700 calories. Peat says a ward study found some women, especially chronic dieters, maintained weight on 700 calories due to adaptations to poorly balanced dieting.
Case presentation of 39-year-old woman with nasal congestion, throat tightness, swollen eyes, and persistent flu-like symptoms for months, plus cold intolerance, constipation, weight gain. Diagnosed with hypothyroidism and treated with levothyroxine 150 mcg. All symptoms resolved by 12 weeks. Embedded quoted post explains mechanism: thyroid hormone receptors in nasal mucosa cause edema and inflammation when thyroid hormone is low.
5-HTP may lower bone density. Higher plasma 5-HTP levels correlate with osteoporosis in women. Animal studies show 5-HTP increases bone loss in periodontitis, accelerates bone demineralization in cows. Mechanism: 5-HTP increases serotonin, which has bone-dissolving action.
lowmegatron quotes a review saying that genetic skeletal dysplasias showed that gut enterochromaffin serotonin synthesis affects bone. Inhibiting it could treat low bone mass diseases such as osteoporosis. He adds that serotonin-lowering drugs treat osteoporosis in animals by targeting the step converting tryptophan to 5-HTP.
lowmegatron quotes a study saying once-daily oral administration of a small molecule for up to six weeks treated osteoporosis in ovariectomized rodents through increased bone formation. It is presented as proof of principle that inhibiting gut-derived serotonin synthesis could be an anabolic osteoporosis treatment. Six PMIDs are listed. The quoted parent, on SSRIs and bone, is not attributed to this post.
Ray Peat recommended oysters for hormonal health due to zinc and selenium content. Zinc replenishment normalizes T3 thyroid hormone and lowers reverse T3 in zinc-deficient individuals. Selenium supports thyroid hormone conversion and reduces thyroid antibodies. Some people find thyroid hormones work better when incorporating oysters. Study citation provided on zinc role in thyroid metabolism.
Hypothyroidism should be considered in differential diagnosis of upper airway obstruction, asthma, sleep apnea, allergic rhinitis, and urticaria/angioedema. Hypothyroidism called 'The Great Pretender' for ability to mimic many diseases. T3 thyroid hormone has central role in energy production; when energy drops, symptoms appear. Allergic-type symptoms downstream of thyroid issues are common and often overlooked. Embedded quoted post references case of 40-year chronic nasal congestion resolved with thyroid hormone.
lowmegatron quotes a report of 'Very good functional improvement' in affected joints. It lists calcification types among patients: myositis ossificans traumatica (24), calcific bursitis (23), elbow osteoarthropathy (6), post-trauma elbow calcification (9), hip calcification (13) and ligament/tendon calcification (5). The treatment is not stated in this post, and its parent is missing.
Ray Peat stated magnesium retained in cells under ATP and thyroid influence acts as calcium antagonist. Magnesium can reverse soft tissue calcification. Study of 80 calcification patients treated with local MgSO4 injection and oral magnesium lactate: 75% cured with calcifications disappearing or diminishing substantially over 2-20 weeks treatment.

Ray Peat's view that glyphosate toxicity operates through DNA regulation mechanisms rather than glycine substitution at small exposure levels.
Hypothyroidism increases susceptibility to various infections (SIBO, candida, shingles, TB, pneumonia) due to insufficient energy production; thymic atrophy from low thyroid hormone, estrogen, and cortisol reduces T-cell production.
Hypothyroidism increases candida infection risk through estrogen dominance, reduced glucose metabolism, and lowered IgA; case example of mucocutaneous candidiasis resolving after thyroid hormone replacement.
Thyroid hormone influences herpes zoster (shingles) outbreak severity; hypothyroidism increases recurrence risk; thyroid hormone replacement therapy reduces shingles risk by 40%.
T3 thyroid hormone suppresses HSV-1 (cold sore virus) replication by inhibiting viral gene expression; hypothyroidism results in increased viral replication and reactivation.
lowmegatron says shingles, cold sores and genital herpes infection and reactivation are more common in hypothyroidism, with higher risk in women. He quotes data giving an odds ratio of 3.40 for females aged 21 and over versus 1.91 for males, which the study authors suggest may reflect hormonal alteration.
Multiple overlooked factors contribute to insulin resistance beyond diet and exercise, including carrageenan, thyroid hormones, minerals, stress, endotoxin, light exposure, vitamins, sleep, and movement.

Magnesium can reverse subclinical hypothyroidism in people without thyroid disease. Magnesium depletion lowers T4, inhibits iodine uptake, and increases thyroid volume in animal studies. Citation provided showing TSH normalization after magnesium supplementation.
lowmegatron quotes a study saying Mg-deficient rats had lower weight gain, lower plasma T4 and Mg, and a relatively heavier thyroid gland.
lowmegatron quotes a rat study (PMID 4133501) reporting a close positive correlation between serum magnesium and thyroid activity as measured by radioiodide handling. Magnesium deficiency or loading did not change thyroid cyclic AMP or hormone release in vitro. Radioiodide accumulation was stimulated by magnesium loading and inhibited by deficiency. The post is a continuation of a thread arguing that magnesium depletion harms thyroid function.

Hypothyroidism causes poor circulation partly due to cold extremities. Correcting thyroid hormone levels improves circulation. T3 restores euthyroid state and normalizes peripheral vascular resistance. Citation provided showing 46% of resistance changes explained by T3.
lowmegatron quotes a paper stating that overt hypothyroidism is associated with decreased cutaneous microvascular blood flow. The author interprets this as reduced small-vessel skin blood flow causing pallor and colder extremities.
lowmegatron says Broda Barnes noted thyroid effects on circulation decades ago. The quoted passage from Barnes's book claims severe hypothyroidism can reduce circulating blood per minute by as much as 40 percent, that even mild reductions impair tissue oxygen delivery, and that this contributes to fatigue and poorer mental function. These are Barnes's claims as quoted.
Chronic stress downregulates thyroid axis adaptively; stress-lowering approaches like yoga can improve thyroid hormones and correct TSH feedback. Quotation attributed to author discussing stress-induced thyroid suppression as hibernation-like adaptation.
lowmegatron quotes a study (PMID 31563038) stating that acute psychosocial stress elicits a significant increase in TSH. The quote says this is relevant to stress-related illnesses with hypothalamic-pituitary-thyroid axis abnormalities.
lowmegatron quotes a study (PMID 29540811) reporting that T3, T4, fT3 and fT4 were decreased in a chronic stress group. The authors of the quoted study interpret this as thyroid dysfunction induced by long-term combined stress.
lowmegatron reports a randomized trial in hypothyroid women in which yoga was followed by T3 up 17%, T4 up 7% and TSH down 26%. He also quotes a review saying four studies indicated yoga improved hypothyroidism by lowering TSH and levothyroxine doses and raising T3 and T4. The quoted context is a Ray Peat quote that stress hormones lower thyroid hormone conversion, so TSH alone cannot diagnose.
Critically ill patients received intravenous soybean oil (Intralipid 82-90% calories) for decades; SMOFlipid, available since early 2000s, reduces soybean oil to 27% of calories. SMOFlipid composition provided with added vitamin E and egg yolk phospholipid.

Vitamin D reduces Candida burden, inhibits growth in culture, prevents yeast-to-hypha switching that enables tissue infiltration and biofilm resistance, reduces inflammation, and is lower in Candida patients. Sunlight and vitamin D-rich foods associated with lower infection risk; vitamin D-rich yogurt reduces ICU Candida infections.
Low blood sugar causes two distinct symptom clusters: neurogenic symptoms from sympathoadrenal activation (anxiety, tremors, palpitations, hunger, sweating, paresthesias) and neuroglycopenic symptoms from nervous system glucose deficiency (confusion, fatigue, seizure, coma, death). Quoted post details hypothyroidism as cause of hypoglycemia and related symptoms.
Glucose metabolism and intelligence are related; variations in learning, memory and problem-solving reflect metabolic differences. IQ correlates strongly with cerebral blood glucose level, brain size, and glucose assimilation after glucose load. Research from 1936 shows basal metabolic rate and thyroid function correlate with intelligence in children.
Progesterone increases expression of genes the thyroid uses for iodine uptake, hormone synthesis and growth. This effect is progesterone-receptor-dependent. Evidence shows free T4 increases and TSH tends lower during progesterone treatment in women.
Women show increased sensitivity to allergens and histamine when estrogen dominates progesterone. Bioidentical progesterone decreases mast cell degranulation. Skin-test reactions to histamine increase at ovulation during peak estrogen. Progesterone reduces mast cell secretion and may explain suppression of inflammatory conditions during pregnancy.
Orange juice lowers insulin, blood sugar, inflammation and improves insulin sensitivity; meta-analysis of 10 RCTs shows effects stronger at ≥500ml/day. Orange juice lowers blood pressure via hesperidin content; 500ml/day reduces endotoxin and endotoxin immune response in high-fat meals. Author contrasts these findings against quoted warning about fructose risks from David Sinclair.
lowmegatron quotes Ray Peat as saying there is an 'anti-sugar cult' and that sugar craving is usually caused by a need for sugar, generally caused by hypothyroidism. The claim is Peat's, presented without supporting data.
Carrot salad lowers cholesterol ~10% possibly via mild antibiotic effect reducing endotoxin; Ray Peat's perspective on cholesterol as protective against toxins.
Magnesium improves insulin resistance, HbA1C, fasting blood sugar in type 2 diabetes and lowers cortisol; high cortisol worsens T2D.
lowmegatron argues that low magnesium in type 2 diabetes and insulin resistance is rarely detected because blood tests measure plasma magnesium, which he says reflects only late-stage deficiency. He says intracellular (RBC) magnesium is a better test. He quotes a source stating intracellular magnesium regulates insulin action and that low levels worsen insulin resistance in T2D. The quoted context says serum magnesium is the only widely available clinical method and advises caution with supplementation in renal failure and with large doses.
Dietary calcium and dairy support weight loss and prevent obesity via appetite suppression and fat oxidation; Ray Peat's observational perspective on milk/cheese consumption and body composition; multiple cited studies on calcium's role in weight regulation.

Consumption of 400g whole oranges daily for 4 weeks reduced fatty liver prevalence by 30%, with 29% of orange group no longer meeting fatty liver threshold independent of body weight changes.
lowmegatron cites a mouse study (PMID 35520248) in which Moro (blood orange) juice counteracted liver steatosis in diet-induced obesity. Blood oranges returned liver triglycerides to levels similar to standard diet, while blond oranges gave only a weak reduction. The quoted context is his own orange juice post, which claims benefits for insulin, blood sugar and endotoxin.
Type II Hypothyroidism describes hypothyroid symptoms despite normal lab thyroid levels, reflecting insufficient tissue-level thyroid hormone activity; basal body temperature assessment combined with labs and symptoms provides more reliable thyroid sufficiency evaluation.
High brain serotonin may cause chronic fatigue syndrome (ME/CFS); mouse studies show high-dose SSRIs induce ME/CFS-like symptoms, and blocking serotonin synthesis mitigates symptoms; hyper-serotonergic hypothesis characterized by low 5-HT1A receptor or 5-HT transporter binding.
lowmegatron explains that lower 5-HT1A binding potential is consistent with receptor downregulation from excess extracellular serotonin. Lower serotonin-transporter binding can mean fewer transporters, less reuptake and higher extracellular serotonin. He quotes a study saying 4 weeks of fluoxetine injection in mice elicited ME/CFS-like behaviors that resolved after 6 weeks of withdrawal.
lowmegatron says that in animals given a high dose of SSRI, blocking serotonin synthesis mitigated CFS-like symptoms. The quote says the fluoxetine-induced fatigue-like and ME/CFS behaviors were considerably reversed by a serotonin synthesis inhibitor.
lowmegatron describes a mouse experiment in which the 5-HT1A 'brake' receptor was knocked down. He says serotonin neurons then stay overactive and the mice show fatigue, pain sensitivity and anxiety like those seen after high-dose SSRI treatment. The quote also reports significantly lower plasma corticosterone in the knockdown mice.
lowmegatron says anxiety and depression are associated with a later chronic fatigue syndrome diagnosis, and that high serotonin in a brain region promotes anxiety and fear in rodents. The quoted earlier post from the same author claims chronic fatigue syndrome is often hypothyroidism, citing a quoted study of lower free T3 and a T3-to-rT3 shift in CFS patients. The post's own text does not make that thyroid claim.
Nobiletin, a citrus flavonoid present in higher concentration in peel than flesh, prevents obesity, hepatic steatosis, dyslipidemia, and insulin resistance in high-fat diet mice with potential therapeutic utility for metabolic syndrome.
Alcohol extract of satsuma citrus peel reduced weight gain, fat mass, blood sugar, fatty liver, inflammation, and triglycerides in obese/diabetic mice; contains compounds found in marmalade and orange products.
lowmegatron quotes a study statement that Citrus unshiu peel contains hesperidin, naringin and nobiletin. The quote says hesperidin and naringin ameliorated hyperglycemia, dyslipidemia and hepatic steatosis in type 2 diabetic db/db mice. The quoted post, from the same author, describes a trial in which people with fatty liver ate 400 g of oranges daily.
Assertion that sunlight, coffee, milk, and orange juice are beneficial despite claims to the contrary; dismisses opposing narratives.

The Hair King · @jamesbondwisdom
jamesbondwisdom describes his own protocol at age 19 of rosemary oil, jojoba oil, scalp massage and weekly 1.5mm dermarolling, with no finasteride or minoxidil. He claims rosemary matched minoxidil in a trial and inhibits DHT locally, that microneedling plus topical treatment gave about 4x the hair count, and that the approach costs $14 versus a $15,000 transplant.
jamesbondwisdom claims five non-patented options work for hair loss: saw palmetto 320mg, pumpkin seed oil 400mg, topical rosemary oil, weekly microneedling and daily scalp massage. He attributes several to DHT or 5-alpha-reductase inhibition, contrasts them with finasteride and transplants, and asserts the industry hides this.
jamesbondwisdom says his thinning at 19 came from chronic stress and caffeine raising cortisol and pushing follicles into telogen, not from genetics. He describes cutting espresso from 5 to 1, plus saw palmetto, rosemary oil, weekly microneedling and scalp massage, and reports visible baby hairs at 3 months.
jamesbondwisdom claims weekly 1.5mm microneedling does more for regrowth than most prescriptions, citing a 2013 study in which adding microneedling to minoxidil gave roughly 4x the hair count increase at 12 weeks. He gives a growth-factor mechanism and instructions on frequency, waiting 24 hours before applying rosemary oil, and a $8 dermaroller cost.
jamesbondwisdom claims most young men's hair loss stems from a self-created hormonal environment: high cortisol, excess body fat raising aromatase and DHT, poor sleep lowering growth hormone, and seed oil inflammation. He advises cutting caffeine, sleeping better, avoiding seed oils and using rosemary oil with weekly microneedling, and says finasteride stops working when stopped.
jamesbondwisdom retweets a truncated post by AlpacaAurelius claiming that daily masturbation is detrimental to men's health because it raises prolactin, which lowers dopamine. The rest of the claim is cut off.
jamesbondwisdom claims that hair loss is follicle miniaturization, not death. In his account, DHT binds androgen receptors and gradually shrinks susceptible follicles, which stay alive and can be recovered while vellus hairs are visible. He says DHT-blocking or follicle-stimulating treatments can reverse this, and that the transplant industry benefits from people thinking their hair is dead.
jamesbondwisdom argues that finasteride blocks 5-alpha reductase and reduces DHT, and regrows hair. He warns of systemic effects on libido, erectile function and mood, cites persistent post-finasteride syndrome, and claims company-funded studies report lower side-effect rates than independent surveys. He suggests topical options and saw palmetto as less effective but local alternatives.
jamesbondwisdom cites a study reporting that 4 minutes of daily scalp massage increased hair thickness over 24 weeks. He attributes this to mechanical stress on dermal papilla cells and to improved blood flow, and criticizes the hair-loss industry.
jamesbondwisdom claims that biotin helps hair only in people who are deficient, which is rare, and that supplements are largely wasted otherwise. He also says high-dose biotin can interfere with lab tests including thyroid panels and troponin, citing an FDA warning, and advises checking for deficiency first.
jamesbondwisdom claims that minoxidil works through blood flow and a longer growth phase, and that stopping causes the gained hair to shed, sometimes leaving users worse off. He frames it as a lifetime commitment.
jamesbondwisdom says that red-light low-level laser therapy (630-670 nm) is FDA-cleared for androgenetic alopecia. He describes a mitochondrial mechanism via cytochrome c oxidase and ATP, cites a meta-analysis of 11 studies, gives usage suggestions, and mentions that devices cost $500-2,000.
jamesbondwisdom claims that a study of 76 men found 400 mg daily pumpkin seed oil raised hair count by 40% versus 10% for placebo over 24 weeks. He attributes this to 5-alpha reductase inhibition and presents it as a cheap alternative to finasteride.
jamesbondwisdom claims that sleep deprivation can cause hair loss 2-3 months later by pushing follicles into telogen, through reduced growth hormone and higher cortisol. He advises fixing sleep before hair treatments.
jamesbondwisdom says that caffeine stimulated follicles and countered testosterone suppression in lab studies. He argues shampoo contact time is too short for scalp penetration and suggests longer contact or leave-in tonics, while acknowledging no large clinical trial has tested this.
jamesbondwisdom retweets his own truncated post claiming that a study showed pumpkin seed oil increased hair count by 40% in 24 weeks. The rest is cut off.
jamesbondwisdom claims that dermaroller depth matters. He says 0.5 mm needles only improve topical absorption, while 1.5 mm reaches the dermis and triggers a wound-healing response, citing a 2013 study with minoxidil. He gives frequency and aftercare rules and warns of scarring with overuse.
The author claims iron deficiency and low ferritin cause hair loss in men but are rarely checked. He says some researchers suggest ferritin above 70 ng/mL is needed for hair growth, versus a lab 'normal' cutoff of about 20. He recommends asking for a ferritin test and, if below 70, considering iron bisglycinate with vitamin C, away from coffee and dairy.
The author claims gut microbiome disruption drives systemic inflammation and impairs nutrient synthesis, affecting hair growth. He says follicular inflammation contributes to androgenetic alopecia beyond DHT, and that probiotics may help, citing a mouse study with L. reuteri. He suggests fermented foods and avoiding seed oils might help more than topicals.
The author claims hairline recession often starts years before it is noticed. He distinguishes normal maturation (1-1.5cm higher, slight temple recession) from early pattern hair loss, says ages 18-25 are a critical window for early intervention, and urges starting a maintenance protocol at first thinning.
The author presents a sub-$30/month non-prescription hair regrowth protocol: rosemary oil, weekly 1.5mm microneedling, saw palmetto 320mg, pumpkin seed oil 400mg, daily scalp massage, plus sleep, caffeine reduction and morning sun. He claims each component has published evidence and calls the protocol something 'they' want hidden.
A retweet of a post saying someone who tried to save their hairline on advice from looksmaxxers now has erectile dysfunction; the text is truncated and no medicine is named.
The author claims rosemary oil matched 2% minoxidil in a 2015 randomized trial at 6 months and that a 2025 rosemary-lavender trial showed large improvements. He claims a DHT-blocking, vasodilating and anti-inflammatory mechanism, no 'dread shed', and gives usage directions, framing it as an unmarketed cheap alternative.
The author claims microneedling uniquely activates follicle stem cells via wound healing and Wnt/β-catenin, that weekly microneedling with minoxidil gave 4x the hair count increase, and that it boosts topical absorption up to 400%. He gives 1.0-1.5mm weekly protocol and says PRP sessions are overpriced.
The author claims most hair loss stems from restricted scalp blood flow and scalp tension rather than DHT sensitivity alone. He cites laser doppler data (2.6x less flow), botox and scalp massage studies, and recommends massage, inversion, cold rinses, rosemary oil and microneedling, acknowledging inversion has not been formally tested.
The author claims raw onion juice on the scalp produced regrowth in 87% of participants at 6 weeks in a Journal of Dermatology study, attributing it to sulfur, quercetin (5-alpha reductase inhibition), antimicrobial and circulatory effects. He gives application directions and says no one promotes it because of no profit.
A retweet of the author's own truncated post about raw onion juice on the scalp and a dermatology study showing 87% regrowth; only the opening claim is visible.
The author claims pumpkin seed oil, 400mg daily, raised hair count 40% vs 10% placebo in a 2014 double-blind trial, via 5-alpha reductase inhibition and androgen receptor effects, without affecting testosterone or sexual function. He also cites tocopherols, zinc and fatty acids, and suggests oral plus topical use, comparing with finasteride costs and side effects.
The author claims saw palmetto inhibits both 5-alpha reductase types, reduces serum DHT 30-40%, and gives comparable results to finasteride without sexual side effects. He recommends 320mg standardized extract daily and says dermatologists ignore it because it is unpatentable.
A retweet of the author's own truncated post claiming pumpkin seed oil has a randomized double-blind trial showing a 40% hair count increase over 24 weeks.
The author claims red/near-infrared light (630-670nm) boosts follicle ATP via cytochrome c oxidase, citing 14 trials, a meta-analysis of 11 RCTs, and multiple FDA-cleared devices. He says a $60-100 660nm panel can replace $500-1,000 laser caps and gives a usage and stacking protocol.
The author claims chronic cortisol elevation (from poor sleep, stress, overtraining and caffeine) drives stress-related shedding (telogen effluvium) and damages dermal papilla cells, and that topicals like minoxidil cannot overcome this. He recommends 8 hours of sleep, less caffeine, ashwagandha at 600mg and barefoot grounding, and cites figures such as a 37-45% cortisol rise after sleep loss.
The author claims fermented rice water is a traditional hair treatment whose mechanism is confirmed by modern research. He cites Yao women of Huangluo village and says it supplies inositol, 'pitera' and antioxidants, reduces breakage and matches scalp pH. He gives a preparation and use routine.
The author claims topical caffeine stimulates hair follicle growth and counteracts testosterone or DHT suppression. He cites University of Jena ex vivo work showing 33-46% more elongation and suggests coffee rinses or caffeine shampoos such as Alpecin. He says oral caffeine worsens hair loss through cortisol and that microneedling deepens penetration.
The author claims hair loss often originates in the gut through dysbiosis, leaky gut and endotoxin, reduced vitamin and iron absorption, and altered hormone metabolism. He advises avoiding processed foods and seed oils, eating fermented foods, taking probiotics and bone broth.
The author claims black seed oil (thymoquinone) acts against DHT, inflammation, oxidative damage and mast-cell activity in hair loss, and supports angiogenesis. He cites a 90-day topical clinical study and a Prophet Muhammad saying, and recommends 1 tsp orally daily plus scalp massage with a carrier oil.
The author claims seed-oil linoleic acid and a high omega-6 ratio increase inflammation and arachidonic acid/prostaglandin D2, contributing to pattern hair loss. He advises removing seed oils and cooking with butter, ghee, coconut or olive oil.
The author claims stacking a multi-mechanism protocol gives 3-5x better results than single treatments. The stack includes saw palmetto, pumpkin seed oil, no seed oils, omega-3, black seed oil, scalp massage, rosemary, weekly microneedling, zinc, biotin, vitamin D3, sleep, ashwagandha and less caffeine. He gives monthly costs of $40-60.
A retweet of another account's post saying failures don't keep their rooms clean; the text is truncated and unrelated to hair.
The author claims peppermint oil outperformed minoxidil in a 4-week mouse study, via menthol-driven vasodilation, and gives a dilute scalp massage routine. He asserts there is no dread shed and frames it as a cheap alternative to minoxidil.
The author claims vitamin D deficiency stops follicles from cycling into growth, that alopecia patients have lower levels, and that seasonal shedding reflects vitamin D. He recommends 4,000-5,000 IU D3 with K2 and testing, and says the optimal level is 50-70 ng/mL.
The author claims weekly microneedling (1.0-1.5mm) multiplies the effect of other hair treatments, citing a study with 4x the hair count increase versus minoxidil alone and a 400% absorption increase. He recommends a $15 dermaroller and says it equals in-office treatment.
The author claims iron deficiency, shown by low ferritin (below about 40), is an overlooked cause of hair loss and telogen effluvium, that standard blood tests miss it, and that topicals won't work without correcting it. He adds that caffeine reduces iron absorption and vitamin C increases it.
The author claims most people taking biotin for hair are wasting money since deficiency is rare, and that studies showing benefit involved deficient people. He warns that biotin interferes with thyroid and other lab tests and suggests testing iron, zinc, vitamin D and thyroid first. He also claims rosemary oil matches minoxidil.
A retweet of the author's own earlier post about peppermint oil on the scalp, truncated to its opening line; the visible text says peppermint oil sounds hippie-ish until a study is seen.
The author claims green tea EGCG inhibits 5-alpha reductase and lowers DHT, stimulates dermal papilla cells and reduces inflammation, and compares it to finasteride. He recommends 3-4 cups daily plus a scalp rinse.
jamesbondwisdom claims ketoconazole 2% shampoo improved hair density and thickness comparably to 2% minoxidil over 6 months. He attributes this to antifungal action against malassezia, reduced inflammation and a possible anti-DHT effect. He also claims that stopping it causes no shedding, and he suggests stacking it with rosemary or peppermint oil. He says it is cheap and available as Nizoral.
jamesbondwisdom claims that daily scalp massage is a free treatment that gave a 10% increase in hair thickness over 24 weeks. He proposes that it works through mechanotransduction, loosening the galea and improving blood flow. He recommends firm massage, 5 minutes morning and night, and says it carries zero side effects.
jamesbondwisdom claims that castor oil's ricinoleic acid activates EP3/PGE2 signaling and so counters a PGD2/PGE2 imbalance in balding. He cites its viscosity, occlusive effect and anti-inflammatory and antimicrobial properties, and cross-cultural use. He recommends applying it overnight and washing it out with ketoconazole shampoo.
jamesbondwisdom claims that poor sleep undermines hair regrowth. He says 75% of growth hormone is released during deep sleep, that sleep loss cuts growth hormone by up to 70%, and that it raises cortisol and inflammation. He says topical melatonin stimulates hair growth, and he advises 8+ hours of sleep.
jamesbondwisdom claims that rosemary oil matched 2% minoxidil after 6 months in a 2015 randomized trial. He cites a 2025 trial of rosemary-lavender oil, says it blocks DHT and improves blood flow, and claims there is no shedding on stopping. He gives a usage protocol and compares costs.
jamesbondwisdom claims that bone broth supplies amino acids and collagen for keratin and the follicle sheath. He highlights proline and glycine, gut-lining benefits, minerals and silicon, and compares cost with collagen supplements. He recommends 1-2 cups daily.
jamesbondwisdom claims that seed-oil linoleic acid feeds arachidonic acid and PGD2, which suppresses hair growth and drives follicle miniaturization. He says an omega-6 overload is involved, that olive oil cut inflammatory markers 30-40%, and he advises avoiding seed oils in favor of butter, ghee, coconut or olive oil.
jamesbondwisdom proposes a multi-mechanism hair-regrowth protocol. It includes saw palmetto, rosemary oil, green tea, seed-oil removal, omega-3, ketoconazole shampoo, scalp massage, microneedling, ferritin, vitamin D and zinc, bone broth, sleep and stress management. He claims it is cheaper than finasteride and has no systemic side effects.
jamesbondwisdom claims that a randomized, double-blind trial of 76 men showed a 40% hair-count increase versus 10% with placebo on 400mg pumpkin seed oil over 24 weeks. He attributes it to 5-alpha reductase inhibition, says no side effects were reported, and compares it favorably with finasteride.
jamesbondwisdom claims that saw palmetto 320mg daily blocks 5-alpha reductase and improved hair growth in 38% of patients in a 24-month study. He says finasteride reached 68% but had sexual side effects. He also claims it reduces DHT by about 32% and he gives dosing and costs.
jamesbondwisdom claims stinging nettle root extract blocks DHT through three mechanisms (5-alpha-reductase inhibition, SHBG binding, and aromatase inhibition) and also reduces inflammation and oxidative damage. The post compares it with finasteride, saw palmetto and minoxidil and suggests 300-600mg daily of standardized root extract, not leaf.
jamesbondwisdom claims topical caffeine stimulated hair follicle growth faster than minoxidil in a lab comparison via PDE inhibition and cAMP. The post also claims caffeine counteracted testosterone-induced suppression, and recommends caffeine shampoos such as Alpecin, alone or alternated with ketoconazole.
jamesbondwisdom claims raw egg yolk applied to the scalp contains a peptide that stimulates dermal papilla cells via VEGF, and that egg yolk supplies biotin, lecithin, cholesterol, minerals and amino acids for hair. The post gives a weekly egg yolk and olive oil mask recipe.
jamesbondwisdom claims coconut oil is the only oil shown to penetrate the hair shaft and reduce protein loss, because of its lauric acid. The post also claims antimicrobial and anti-inflammatory scalp benefits and suggests pre-wash application.
jamesbondwisdom claims sudden hair shedding (telogen effluvium) is mainly driven by chronic stress and cortisol, not the scalp. He says topical products cannot fix it and recommends 8 hours of sleep, less caffeine, walking and stress reduction.
jamesbondwisdom claims black seed oil (Nigella sativa, thymoquinone) improved hair density in telogen effluvium with no side effects, via anti-inflammatory, antioxidant, antihistamine and antimicrobial actions. He suggests topical use three times weekly and oral use.
jamesbondwisdom claims omega-3 increased hair density and diameter and reduced telogen hairs. He attributes this to prostaglandin shifts, reduced cytokines, membrane effects and EPA inhibiting 5-alpha-reductase. He suggests 2-3g of EPA+DHA daily or fatty fish.
jamesbondwisdom claims commercial shampoos raise scalp pH and damage the cuticle, and that an apple cider vinegar rinse restores pH 4.5-5.5, closes the cuticle and reduces microbes and itching. He gives a diluted rinse routine two to three times weekly.
jamesbondwisdom claims 60% of men with hair loss have untested zinc deficiency, that zinc inhibits 5-alpha-reductase, and that coffee and phytates impair absorption. He advises testing serum zinc (above 80 mcg/dL for hair) and suggests 30mg daily of zinc picolinate or other well-absorbed forms.
jamesbondwisdom claims aloe vera gel exfoliates the scalp with enzymes, has anti-inflammatory activity comparable to hydrocortisone, stimulates FGF via acemannan, and matches scalp pH. He gives an application routine.
jamesbondwisdom claims oral collagen peptides raise proline and hydroxyproline, support the collagen sheath around follicles, and improve hair thickness. He suggests 10-15g daily of hydrolyzed collagen, or bone broth.
jamesbondwisdom claims that men who stop shampooing ("no poo") accelerate androgenetic hair loss because sebum-borne DHT accumulates on the scalp, along with malassezia growth and oxidized sebum. He recommends shampooing two to three times weekly with a gentle shampoo or ketoconazole.
jamesbondwisdom repeats the instruction to start massaging the scalp five times, with no explanation or evidence.
jamesbondwisdom claims rosemary oil matched 2% minoxidil over 6 months in a randomized trial, without minoxidil's side effects or dependency. He attributes this to vasodilation, 5-alpha reductase inhibition, anti-inflammatory and antimicrobial effects. He gives a dilution, massage and frequency protocol and claims dermatology doesn't promote it because there's no revenue in it.
jamesbondwisdom claims microneedling plus minoxidil produced a 300% greater hair count increase than minoxidil alone at 12 weeks, citing a 2013 study. He attributes this to wound healing, Wnt/β-catenin signaling, growth factors and increased topical absorption. He gives a weekly 1.5mm derma roller protocol and contrasts its cost with transplants and PRP.
jamesbondwisdom claims 3% peppermint oil increased hair growth by about 800% over 4 weeks and outperformed minoxidil in every measured category. He attributes it to menthol vasodilation, anti-inflammatory and antimicrobial effects and IGF-1 expression. He gives a diluted application protocol and says dermatologists don't mention it.
jamesbondwisdom claims saw palmetto inhibits 5-alpha reductase like finasteride, reducing DHT by about 32% with essentially no sexual side effects. He cites improved hair quality in 60% of participants and says it can be stacked with pumpkin seed oil. He recommends 320mg daily and says it is unpromoted because it yields no pharmaceutical revenue.
jamesbondwisdom claims caffeine shampoo counteracts testosterone-driven follicle suppression, citing German research from the University of Jena, and that the industry labels it 'volumizing' to avoid regulation. He recommends leaving it on the scalp 2-3 minutes and alternating with ketoconazole shampoo. He names Alpecin as the most studied brand with its price.
jamesbondwisdom claims 400mg/day pumpkin seed oil raised hair count 40% at 24 weeks versus 10% for placebo in a randomized double-blind trial. He attributes it to phytosterols inhibiting 5-alpha reductase, claims zero sexual side effects, and gives a dosing and stacking protocol.
jamesbondwisdom claims a Japanese study showed 4 minutes of daily scalp massage over 24 weeks increased hair thickness by about 10%. He explains it through mechanical stress signaling, blood flow, galea tension and cortisol, and gives a technique. He contrasts it with the cost of laser caps, PRP and transplants.
jamesbondwisdom claims EGCG from green tea inhibits 5-alpha reductase, stimulates dermal papilla cells, extends anagen and reduces inflammation. He recommends a green tea rinse or 400-800mg EGCG capsules and says the industry ignores it because it can't be patented.
jamesbondwisdom claims FDA-cleared low-level laser therapy increases hair density through photobiomodulation at 650-670nm. He cites a sham-controlled trial showing a 37% density increase and says it has no documented side effects. He recommends home laser combs or caps three times weekly and claims dermatologists prefer prescribing finasteride.
jamesbondwisdom claims hair loss may be vitamin D deficiency disguised as genetics, citing lower vitamin D in people with alopecia, follicle VDR and knockout mice. He suggests testing, then supplementing 5,000-10,000 IU daily if below 30 ng/mL, with K2 and fat, and claims dermatologists skip the test.
jamesbondwisdom claims black seed oil and its thymoquinone reduce hair loss through anti-inflammatory, antioxidant and anti-5-alpha-reductase effects. He cites a telogen effluvium study, gives topical and oral protocols, and claims the industry avoids mentioning it.
jamesbondwisdom claims shampoo disrupts scalp pH and that an apple cider vinegar rinse restores it, closes the cuticle, reduces malassezia and normalizes sebum. He gives a dilution and frequency protocol and says the haircare industry sells pH conditioners to fix problems its shampoos cause.
jamesbondwisdom claims collagen decline with age impairs the follicle's matrix and that 15-20g daily hydrolyzed collagen peptides with vitamin C support hair growth, skin and nails. He cites glycine and proline as limiting for keratin and claims the hair industry ignores structural support.

The author claims every follicle is either thickening or miniaturizing, that DHT drives miniaturization in susceptible follicles, and that it is reversible early but hard to recover after 10+ years. He suggests blocking DHT with ketoconazole, saw palmetto, rosemary or finasteride, plus microneedling.
The author claims dermatologists receive minimal hair loss training and default to finasteride and minoxidil, while natural options (rosemary, ketoconazole, saw palmetto, pumpkin seed oil, microneedling, GHK-Cu, red light) have clinical support. He cites finasteride sexual side effects at 3-8% and says topical finasteride has fewer systemic effects.
The author claims there is a roughly 5-year window after thinning starts before follicles become unrecoverable without a transplant. He says early treatment with ketoconazole shampoo, rosemary oil and weekly derma rolling can halt miniaturization, and contrasts a $50/month protocol with a $15,000 surgery.
The author claims topical 0.1% melatonin increased hair density 29% in 6 months in a trial and that European clinics have used it for 20+ years. He says it works by antioxidant action, anagen extension and mitochondrial support, and gives a DIY recipe of a 3mg tablet in 30ml carrier oil.
The author claims cotton pillowcases cause friction, breakage and traction damage, and that silk or satin pillowcases cut breakage by 43% and preserve topical treatments applied at night. He also cites facial skin benefits.
The author claims minoxidil began as an oral blood-pressure drug whose hair-growth effect was a side effect, that its manufacturer says the mechanism is "not fully established", and that it causes dependency, shedding, irritation and non-response in many users. He presents rosemary oil, ketoconazole, microneedling, GHK-Cu and red light as alternatives with clearer mechanisms.
The author claims iron or ferritin deficiency, even without anemia, is a common hidden cause of hair shedding and telogen effluvium. He says ferritin should be tested and kept around 70-80 ng/mL, discusses absorption factors, and suggests iron bisglycinate 25-50 mg daily with vitamin C (his suggestion, not verified).
The author claims a 6-month trial of 100 men found rosemary oil matched 2% minoxidil in hair count with less scalp itching. He attributes this to carnosic acid and improved circulation, and gives an overnight scalp-massage protocol with jojoba carrier oil.
The author recounts James Hamilton's 1942 observations that castrated men did not develop pattern baldness and that testosterone triggered loss in genetically predisposed men. He concludes that DHT acting on vulnerable follicles causes male pattern baldness and that finasteride, saw palmetto and ketoconazole target this mechanism.
The author claims a 12-week study of 100 men found weekly 1.5 mm dermarolling plus 5% minoxidil gave about 4x the new hairs of minoxidil alone (91 vs 22). He cites wound-healing, stem-cell and absorption mechanisms and gives a microneedling protocol.
The author tells the story of Julianne Imperato-McGinley's 1974 study of guevedoces in the Dominican Republic, who lack 5-alpha reductase, have normal testosterone and reportedly never go bald. He says this led Merck to develop finasteride, which shows baldness depends on one blockable enzyme step.
The author claims a 6-month trial of 210 men found 0.2% topical caffeine non-inferior to 5% minoxidil. He cites lab findings on caffeine countering testosterone's effect on follicles, fast follicular penetration and persistence for 48 hours, and recommends caffeine shampoo or serum.
The author claims DHT drives beard growth yet causes scalp follicle miniaturization in genetically predisposed men, which he calls the androgen paradox. He says effective treatments target DHT rather than testosterone.
The author claims standardized daily scalp massage increased hair thickness in a Japanese 24-week study, and that 68.9% of 340 surveyed people reported stabilized or regrown hair. He cites mechanotransduction, blood flow and galea tension and recommends 4-20 minutes daily for at least 6 months.
The author explains that hair shedding lags its trigger (stress, crash dieting, illness) by 2-3 months as follicles move to the resting phase. He advises looking back about 3 months for causes and judging treatments no sooner than month 4, and calls crash diets a common trigger.
The author claims a 2-year trial of 100 men found 320 mg saw palmetto improved hair in 38% versus 68% for 1 mg finasteride, with no reported side effects in the saw palmetto group. He presents it as a weaker 5-alpha-reductase inhibitor and suggests stacking with ketoconazole and pumpkin seed oil.
The author claims wet hair is up to 50% weaker and that rough towel drying, brushing and high heat cause breakage that is mistaken for thinning. He recommends blotting, using a wide-tooth comb and air drying.
The author claims a 2014 four-week mouse study found 3% peppermint oil outperformed 3% minoxidil (92% vs 55% hair growth score) and raised IGF-1. He acknowledges it was in mice, says no human trials followed because peppermint cannot be patented, and gives a diluted-application protocol.
The author argues that some hair loss reflects nutritional or thyroid problems rather than genetics, and suggests testing ferritin, vitamin D, TSH and zinc. He says DHT loss follows a pattern (temples, crown) while deficiency loss is diffuse, and tells readers to run the panel before buying topicals.
The author claims a randomized, double-blind trial of 400mg daily pumpkin seed oil in 76 men raised hair count 40% over placebo at 24 weeks. They attribute this to delta-7 sterol blocking 5-alpha reductase and say it is an alternative to finasteride with no sexual side effects. They also claim it contains zinc, vitamin E and omega fatty acids, and that dermatologists ignore it.
The author claims the body's GHK-Cu copper peptide declines with age (60% less by 40) and that it reverses follicle miniaturization by altering gene expression (Wnt, beta-catenin, DKK1, TGF-beta), boosting collagen and angiogenesis. They recommend a 1-2% serum 3-4 times weekly, ideally with microneedling.
The author claims low-level red light therapy (650-670nm, 15-25 min, 3x weekly) is supported by 14 RCTs, FDA-cleared, and raises hair density 35-50%. They describe a mechanism via cytochrome c oxidase, nitric oxide, increased ATP and reduced prostaglandin D2, and say panels cost $30-150.
The author claims aggressive caloric restriction causes telogen effluvium 2-4 months later, through drops in leptin, T3 and IGF-1 and inadequate protein. They advise a deficit of no more than 500-700 calories, at least 1.2g/kg protein, weekly refeeds, and iron and zinc supplementation.
The author claims vitamin D receptors on follicles are needed to start the growth phase and that low vitamin D is linked to hair loss. They cite 96.7% deficiency in 80 women with telogen effluvium, argue for a 50-80 ng/mL target, and suggest 2,000-5,000 IU D3 with K2 and retesting at 3 months.
The author claims biotin supplements are a $3 billion scam, because deficiency is rare and there is no RCT showing benefit in non-deficient people. They say the company-cited studies involve deficient patients, and that money is better spent on rosemary oil, ketoconazole shampoo and a derma roller, plus testing iron, zinc and vitamin D.
