Rawji et al. 2024, magnesium for anxiety and sleep quality

Cureus systematic review of supplemental magnesium for self-reported anxiety and sleep quality. Of eight sleep studies, five reported generally positive results, two negative and one mixed. The authors stressed that firm conclusions were limited by heterogeneous data, small samples and varied dose, form and duration, and that magnesium is likely useful mainly in people with low baseline status. Observational links are stronger than the interventional evidence; larger trials are needed. A thin, low-quality base behind the “magnesium for sleep” marketing.
