Melatonin
Micro-dose for sleep architecture and circadian rhythm. Bryan uses the micro-dose form, not pharmacy 3–10 mg tablets.
Dose & timing
- 300 mcg — before bed
Why it’s in the stack
0.3 mg is the physiological replacement dose (Wurtman & Lewy, MIT). Standard 3–10 mg pharmacy doses flood receptors, often cause next-day grogginess, and may downregulate endogenous production. Lower-dose advocates argue the 0.3 mg target preserves circadian benefit without the receptor saturation.
