Supplement-Specific Guidance
Most people get ~200–300 mg/day from food, so typical supplement doses are:
- 100–200 mg/day → for minor deficiency or sleep support
- 200–400 mg/day → common range for sleep, muscle recovery, or stress
- 400+ mg/day → not usually needed unless medically indicated
Upper Limit (Safe Supplemental Max)- 350 mg/day from supplements only
Some people tolerate more, but above ~350 mg/day of supplemental magnesium can cause GI issues, depending on the type (oxide → worst; glycinate → best tolerated).(This doesn't include food sources.)
