Magnesium is a common mineral in the human body, involved in hundreds of body reactions, from muscle health to metabolism. Magnesium is found in many foods; it is especially abundant in whole grains, nuts and seeds, and leafy green vegetables, such as spinach. Meat, dairy foods and mineral water also contain fairly high amounts of magnesium. Should you consider taking a magnesium dietary supplement? Low magnesium can contribute to fatigue and muscle weakness.
