Dose and safetyThe dose that worked and the upper limit
The studies of magnesium oxide taken by mouth that showed an improvement gave 50 mg to 1.5 g a day.
The upper limit from supplements is 350 mg of magnesium a day, counted as the magnesium itself, not the weight of the compound; above it, members see a note and are told they can take less.
