Adult women between the ages of 19 and 50 need 18 mg of iron each day, and men the same age require 8 mg, according to the recommendations of the Institute of Medicine's Food and Nutrition Board. The recommendation for both men and women 51 or older is only 8 mg.
Iron is not made in the body and must be absorbed from what you eat. The adult minimum daily requirement of iron is 1.8 mg. Only about 10 to 30 percent of the iron you consume is absorbed and used by the body. The daily requirement of iron can be achieved by taking iron supplements.
