The science of better sleep: a magnesium + glycine + apigenin stack

Sleep is more than duration

Total sleep time matters, but so does sleep architecture — the ratio of slow-wave (deep) sleep and REM that determines how restored you feel. Most adults over 35 lose deep sleep first.

Why melatonin is overused

Melatonin is a circadian signal, not a sedative. It's powerful for jet lag and shift work at 0.3–0.5 mg, but the 5–10 mg doses sold OTC suppress endogenous production and often produce next-day grogginess.

The evidence-backed sleep stack

Magnesium glycinate (300 mg) supports GABA activity and muscle relaxation. Glycine (3 g) has been shown to lower core body temperature and improve subjective sleep quality. Apigenin (50 mg, from chamomile) binds benzodiazepine receptors gently and shortens sleep onset.

Stacked 60–90 minutes before bed, this combination has been studied for improving deep-sleep percentage without altering REM.
