- After 6 wk, magnesium supplementation was associated with reduced symptoms of depression and anxiety, but the study did not include a placebo control.
Why this matters
- Magnesium supplementation is safe and inexpensive.
- 108 adults with depression were randomly assigned to 6 wk of treatment (248 mg of elemental magnesium per day) or to delayed treatment.
