A dietary supplement added to formula feeds, other manufactured foods, or regular diets. Additional “mineral” content is often combined with vitamins. The most widely used minerals include iron, magnesium, and calcium. Iron supplements sometimes help persons with iron-deficiency anemia, but iron is more often taken in pills. Calcium is added to milk, orange juice, etc. Magnesium is seldom required as a supplement unless foods containing chlorophyll are unavailable. Iodine (not a mineral) is added to table salt. Various other supplements are also used. See http://www.nlm.nih.gov/medlineplus/vitaminsandminerals.html for indications and details.
