Magnesium Glycinate: Benefits, Sleep and How It Compares
Magnesium glycinate is magnesium bound to glycine, also sold as magnesium bisglycinate. In the only sleep trial of this form, 155 adults who took 250 mg of magnesium a day for 4 weeks slept a little better than with placebo, but the effect was small. Adults should keep supplement magnesium at or under 350 mg a day, and people with kidney disease should ask a doctor first.
