Smaller amounts of iron are found in myoglobin, a protein that helps supply oxygen to muscle, and in enzymes that assist biochemical reactions in cells. About 15 percent of your body's iron is stored for future needs and mobilized when dietary intake is inadequate. The remainder is in your body's tissues as part of proteins that help your body function. Adult men and post-menopausal women lose very little iron except through bleeding.
