Magnesium is an important part of the more than 300 enzymes found in your body. Enzymes are body chemicals that helps regulate many bodily functions, including the production of energy, body protein and muscle contractions. It also plays a role in maintaining healthy bones and a healthy heart.
Magnesium is a major mineral, meaning it exists in your body in significant amounts. The average person needs to consume between 300 and 400 milligrams of magnesium a day.
Foods rich in magnesium include green leafy vegetables, whole grains, beans and nuts. Fresh fruits and vegetables also provide a modest amount of magnesium.
