FAQs

How much magnesium do adults need each day?

Recommended amounts vary by age, sex, and life stage. For adults, the recommended dietary allowance is generally 400–420 mg per day for men and 310–320 mg per day for women. Requirements differ during pregnancy and for younger age groups.²

What does “elemental magnesium” mean?

Elemental magnesium is the amount of magnesium the supplement provides. The complete magnesium compound weighs more because it also includes the substance bound to the magnesium. Check the label for the amount of magnesium supplied per serving.⁴

Yes. Higher amounts of supplemental magnesium can cause diarrhea, nausea, or abdominal cramping in some people. Follow the product label and speak with a healthcare practitioner if you have concerns.³
