The effect of magnesium supplementation on primary insomnia in elderly: a systematic review
Mah J, Pitre T
Published in BMC Complementary Medicine and Therapies
Key Findings
Three RCTs showed magnesium reduced sleep onset latency by about 17 minutes versus placebo, with no significant change in total sleep time.
Conclusions
Evidence for oral magnesium in insomnia is of very low quality and effects are modest.
Limitations
Only three small trials, all at risk of bias.
Supplements Studied
Magnesium supplementation decreased sleep onset latency by approximately 17 minutes, but the quality of evidence was very low.
Outcomes Measured
Magnesium supplementation decreased sleep onset latency by approximately 17 minutes.
Post-intervention sleep onset latency time was 17.36 min less after magnesium supplementation compared to placebo (95% CI - 27.27 to - 7.44, p = 0.0006).
