Summary

This study tested whether taking 400 mg of magnesium citrate daily for 90 days could improve sleep quality and cognitive function in healthy Saudi adults who reported poor sleep. Researchers compared 41 participants who took the supplement to a control group that took nothing. The study measured sleep using a standard questionnaire and thinking speed with a trail-making test.
