lowmegatron says high-dose T4 has been used in bipolar depression.

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 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.

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.

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.

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.

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.

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.

Trace lithium (lithium orotate, 1–20 mg daily) is distinct from pharmaceutical lithium carbonate (600–1,800 mg for bipolar disorder). Epidemiological studies in multiple countries show regions with higher natural drinking water lithium have significantly lower suicide rates, violent crime, and dementia. Trace lithium supports BDNF production, protects against glutamate excitotoxicity, and stabilizes mood via GSK3-beta inhibition at neuroprotective doses without psychiatric-grade side effects. Recommended dose 5–10 mg evening; cost ~$10/bottle.

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.

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.

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.
Source summary and thread relationship - @lowmegatron · 2026-09-22 own thread
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.
