Condition depression
Treatment magnesium chloride
Phase phase 2/phase 3
Sponsor University of Vermont
Start date May 2015
End date December 2017
Trial size 100 participants
Trial identifier NCT02466087, M15-337


The objective of this project is to test the hypothesis that magnesium supplementation will decrease depressive symptoms in adults.

This study takes place over 12 consecutive weeks. While the investigators will follow the volunteers for the full 12 weeks volunteers will only take magnesium supplements for 6 consecutive weeks. Volunteers will be randomly assigned to start the supplement at week 1 or week 7. Volunteers will take two supplement two times a day for a total of 248 mg elemental magnesium daily in the form of magnesium chloride. This amount of magnesium is less than the tolerable upper limit of 350 mg per day. The supplements will be provided. Volunteers will be asked to maintain their normal diet for the 12 weeks of the study.

The primary outcome measure is the PHQ-9 questionnaire, a validated measure of depression. Secondary measures include the GAD-7 for Anxiety and side effects.
