Evidence is still building up
Summary
A double-blind, placebo-controlled RCT giving magnesium 500 mg/day for 8 weeks to 46 elderly adults with primary insomnia. Subjective sleep time and sleep efficiency improved significantly, early morning awakening decreased, and serum melatonin and renin rose while cortisol fell. Because participants were elderly, the results may not generalize to young athletes, and the sample size was small.
Key findings
- 1
Subjective sleep time and sleep efficiency improved significantly
- 2
Early morning awakening decreased significantly
- 3
Serum renin and melatonin increased, cortisol decreased
