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.

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.'

99% of vitamin B6 supplements contain pyridoxine, the inactive form; approximately 1 in 3 people cannot convert it efficiently. The active form P5P (pyridoxal 5-phosphate) is required for neurotransmitter synthesis. Author recommends specific dosing and brands with pricing.

The author claims a "gut hair axis" in which gut microbiome disruption drives hair loss. Claimed pathways are reduced biotin production, systemic inflammation and endotoxin from leaky gut, and low serotonin raising cortisol and causing telogen effluvium. The post blames antibiotics and the Western diet. It recommends fermented foods, prebiotic fiber, and L. reuteri probiotics, with stated timelines and costs.

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.

Multiple overlooked factors contribute to insulin resistance beyond diet and exercise, including carrageenan, thyroid hormones, minerals, stress, endotoxin, light exposure, vitamins, sleep, and movement.

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.
