Related pairings
Glycine + Magnesium
A sleep pairing with a built-in shortcut: magnesium glycinate is magnesium bound to glycine, so that form already delivers both. A standalone 3 g dose before bed (the amount sleep studies used) tops up the glycine, lowering core body temperature while magnesium relaxes muscles and calms the nervous system.
Magnesium + Vitamin D3
Magnesium is required to convert vitamin D into its active form, so low magnesium blunts D3's benefits.
L-Arginine + Magnesium
Magnesium supports vascular smooth muscle relaxation alongside nitric oxide from arginine.
Ashwagandha + Magnesium
Commonly combined for stress relief and better sleep quality.
