Magnesium

A structural component of bones, magnesium is involved in over 300 enzyme systems. Magnesium is required for energy production, heart and nerve function, supplying the compounds necessary for DNA and RNA synthesis during body cell replication and keeping potassium levels consistent.

Food & Beverage Sources

Magnesium is found in whole grains, broccoli, potatoes, squash, beans, nuts and seeds. Meat, milk and chocolate also supply some magnesium, although animal sources typically contain less magnesium than plant sources.

Beverages including milk and milk-based products, tap water with a high mineral content and coffee may contain magnesium.

Recommended Intake Levels

The adult recommendation for magnesium is 310-420 milligrams daily for adults over age 18 and increases to 360-400 milligrams daily during pregnancy, and 320-360 milligrams daily during lactation. The recommended intake levels for women are slightly lower than men (about 320 milligrams versus 420 milligrams daily). On average, men and women consume about 100 milligrams less magnesium than the recommended amount.
