Magnesium Overload: When Supplements Go Overboard
Magnesium is essential and best met through a balanced diet, but excess comes from supplements (hypermagnesemia), with adults advised to cap supplemental magnesium at 350 mg/day; dietary needs are about 320 mg for women and 420 mg for men, so focus on magnesium-rich foods like leafy greens, nuts, seeds, legumes, whole grains, and dairy, using supplements only if needed and under medical guidance.
