Influencer sleep powders sell you cocoa flavor and marketing wrapped around a few cents of actives — and usually dust the magnesium down to a fifth of the studied dose. This stack is the calming core at full strength: magnesium glycinate, glycine and L-theanine. Mix into a glass of water 30–60 minutes before bed. (Add a pinch of melatonin only if you actually need help falling asleep — most people don't.)
