Recommended daily intake of iron

Iron plays an essential role in delivering oxygen to the body via the bloodstream. It also has many muscular and metabolic functions. A lack of iron can lead to anemia and reduce your resistance to infection. Studies show that iron supplements can prevent or treat iron deficiency anemia. Research also has demonstrated that iron supplements may benefit women during menstruation or pregnancy. Iron deficiency is uncommon in postmenopausal women.

(i)There is evidence that iron absorption can be significantly enhanced when each meal contains a minimum of 25 mg of Vitamin C, assuming three meals per day. This is especially true if there are iron absorption inhibitors in the diet such as phytate or tannins.
(k)Neonatal iron stores are sufficient to meet the iron requirement for the first six months in full term infants. Premature infants and low birth weight infants require additional iron.
(l)Bio-availability of dietary iron during this period varies greatly.
(m)Non-menstruating adolescents.
(n)It is recommended that iron supplements in tablet form be given to all pregnant women because of the difficulties in correctly evaluating iron status in pregnancy. In the non-anaemic pregnant woman, daily supplements of 100 mg of iron (e.g., as ferrous sulphate) given during the second half of pregnancy are adequate. In anaemic women higher doses are usually required.
