<p>Iron is an essential constituent of the body being necessary for haemoglobin formation and for the oxidative processes of living tissues. Iron salts should only be given for the treatment and as prophylaxis of Iron deficiency anaemia. Iron deficiency anaemias are most often the result of chronic haemorrhage, nutritional deficiency, pregnancy or parasite infestation or malabsorption of iron.<br />
<br />
A deficiency of Folic acid typically during pregnancy has long been known to cause a megaloblastic anaemia. The vitamin is not storable in the body and the combination of fetal demand during pregnancy and malnutrition can lead to a deficiency, hence anaemia. It has been observed that the rapid production of red blood cells following treatment with iron may deplete body folate if there is inadequate intake; combination of folic acid and ferrous fumerate avoids the complication. Iron and Folic acid are absorbed in the proximal small intestine particularly the duodenum. Ferrous Fumerate &amp; Folic acid supplements replenish iron deficiency. Thereby arresting the anaemia process. Absorbed iron is taken upto the bone marrow&#39;s tissues that form blood cells where it is used to synthesize haemoglobin.</p>
