Magnesium is vital for regulating muscle and nerve function, blood sugar levels, blood pressure, and for making protein, bone, and DNA. The current research suggests that most American adults do not consume adequate amounts of magnesium in their diet. Dietary sources of magnesium include legumes, nuts, seeds, whole grains, green leafy vegetables, fortified breakfast cereals and other fortified foods, milk, yogurt, and some other milk products.
