The Claim
After 4 weeks of magnesium bisglycinate supplementation, although there is a statistically significant improvement in insomnia severity, the mean Insomnia Severity Index score remains in the subthreshold insomnia range, suggesting that magnesium bisglycinate supplementation alone is unlikely to eliminate insomnia in many individuals.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking a magnesium supplement for 4 weeks can improve sleep problems, but the average score on a sleep questionnaire still shows some insomnia. So the supplement by itself does not cure insomnia for most people.

The supplement gives the body more of two important substances: magnesium and glycine. Magnesium helps the brain's calming system work better, making nerve cells less jumpy. It also helps muscles relax. Glycine also calms the brain and makes the body slightly cooler, which helps sleep. Together, these effects make it easier to fall asleep, but they don't fix sleeplessness completely for most people.
What the research says
1 studyThe study shows that magnesium helps a little bit with sleep, but most people still have some sleep problems after taking it.
