According to the National Institutes of Health, the Tolerable Upper Intake Level (UL) for supplemental magnesium is 350 mg per day for adults over nine years old. While taking 400 mg of magnesium glycinate at once may not be immediately dangerous for a healthy individual, it exceeds the recommended daily limit for supplements and could lead to side effects.
