Why your sleep stack needs more than melatonin

Sleep is not a single switch but a sequence: winding down the nervous system, relaxing tense muscles, and keeping cortisol from spiking overnight. Magnesium glycinate, ashwagandha, glycine, and low-dose melatonin each target a different link in that chain — and that is why combining them often outperforms doubling up on any single one.

The highest-value starting point is magnesium glycinate 30-60 minutes before bed: it supports GABA activity and muscle relaxation without next-morning grogginess. If stress is what keeps you awake, ashwagandha taken at dinner works on a 2-4 week timeline to lower evening cortisol. Melatonin is a timing tool, not a sedative — 0.5-1mg an hour before bed shifts your rhythm without the hangover of mega-doses.

Below you will find the most evidence-backed sleep supplements, the combinations with real synergy, and the interactions worth knowing — every guide includes timing details and product picks.
