Most magnesium is found in the cell where it activates the enzymes necessary for the metabolism of carbohydrates and amino acids. It is involved in insulin secretion and function. Magnesium has been shown to reduce hyperactivity in children who had low magnesium levels. It may improve vision in glaucoma patients, lower blood pressure, and may be a factor in chronic fatigue syndrome. The mineral is refined out of many foods and amounts are lost during cooking of foods.
