The iron content of the body is highly conserved (Bothwell et al 1979). To achieve iron balance, adult men need to absorb about 1 mg/day and adult menstruating women about 1.5 mg/day, although this is highly variable. Towards the end of pregnancy, the absorption of 4-5 mg/day is necessary. Requirements are higher during periods of rapid growth in early childhood and adolescence.
A , Internal Medicine, answered. To replace iron lost during monthly periods, you need a diet rich in iron. In the United States, one in 10 women and girls who menstruate is deficient in iron. The recommended daily amount of iron for adult women ages 19 to 50 is 18 mg. If you are a menstruating woman, you may wish to take a multivitamin that contains iron, or check with your doctor to see if need iron supplements.
