Magnesium Supplementation Improves Sleep Quality in Elderly with Insomnia
Does Magnesium Supplementation Help Elderly Adults Sleep Better?
Yes, this double-blind placebo-controlled study demonstrates that magnesium supplementation significantly improves sleep quality in elderly adults with primary insomnia. Participants taking 500mg of magnesium daily for 8 weeks showed substantial improvements in sleep efficiency (from 75% to 85%), total sleep time (increased by 17 minutes), sleep onset latency (reduced by 7 minutes), and early morning awakening. The study also found improvements in serum melatonin and cortisol levels, suggesting that magnesium helps regulate the hormonal systems involved in sleep-wake cycles.
