Does magnesium help with sleep?
Magnesium may help sleep a little, but the evidence is thinner than the hype. Small studies suggest mild benefit, mostly in older adults or the deficient, and the popular glycinate form is calming for some. It is not a sleeping pill.
Magnesium is reasonably safe at modest doses, though it loosens stools and interacts with some medicines, so kidney disease changes the calculus.
Try it if you like for a month as an experiment, but the durable wins remain unglamorous: fixed wake time, morning daylight, caffeine curfew, alcohol honesty and a cool dark room. No capsule outruns those.
