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.
Potassium is vital for the regular functioning of all of your body's cells, tissues and organs. Unlike minerals such as zinc and iron, women and men do not require different amounts of potassium. According to the Institute of Medicine, all adult women should aim for a daily intake of 4.7 grams of potassium.
