Moderate evidence suggests magnesium glycinate can reduce insomnia severity and improve sleep quality in adults. However, the overall effectiveness varies, and some studies show limited benefits, particularly in older populations.
Sleep quality in adults with poor sleep (magnesium bisglycinate RCT)Adults aged 18–65 with self-reported poor sleep (n=155) · RCT (double-blind, placebo-controlled)Moderate
250 mg elemental magnesium as bisglycinate modestly but significantly reduced Insomnia Severity Index score vs. placebo (−3.9 vs −2.3, p=0.049) by week 4; well-tolerated with minimal GI effects.

Magnesium supplementation reduced sleep onset latency by ~17 min vs. placebo; increased sleep time & efficiency. Evidence rated low-to-very-low quality; all trials at moderate-to-high bias risk.
