Healthy people with good sleep don't usually need magnesium supplements, but if you're deficient (common in India due to diet/soil) or notice poor sleep quality, 200–400 mg of magnesium glycinate nightly can modestly improve sleep onset and depth.
Evidence for sleep benefits
-
Magnesium calms the nervous system by binding GABA receptors, reducing cortisol, and boosting melatonin—trials show better sleep efficiency and less insomnia in those with low levels or mild issues.
-
In healthy adults with self-reported poor sleep, 250–500 mg forms like bisglycinate cut insomnia scores by 20–28% vs. placebo over 4–8 weeks.
When to skip or consider
-
No strong need if sleeping well: Observational data links higher dietary magnesium to better sleep, but supplements add little benefit without deficiency (test serum/RBC levels).
-
Safe for most at 300–400 mg elemental Mg (glycinate best for sleep, less GI upset); pregnant women like you should cap at 350 mg supplemental to avoid excess.
