Most melatonin doses are 10 to 20 times too high:
- Optimal doses for sleep benefits are 0.1 to 0.3 mg
- Pharmacy and online supplements run 1 mg to 20 mg - 10 to 20 times what your body releases
- Dose escalation is a marketing arms race: more milligrams for the same price
- These are supra physiological levels of a hormone that is androgen suppressive when high
- Seasonally breeding animals injected with melatonin had gonads shrink from almond size to a grain of rice
- Animal data only. No specific human study on this
