Iron Polysaccharide

**Semantic type:** Pharmacologic Substance

**Definition:** A delayed-release formulation of iron supplement consisting of an iron atom bound by a polysaccharide molecule. Upon oral administration, there is delayed-release of iron and iron absorption in the stomach and small intestine. The absorbed iron combines with apoferritin to form ferritin, which is stored in the liver, spleen, red bone marrow, and intestinal mucosa. Important in transport of oxygen by hemoglobin to the tissues, iron is also found in myoglobin and transferrin, and is a component of many enzymes such as catalase, peroxidase, and cytochromes. The delayed-release of iron may minimize the gastrointestinal upset caused by iron supplements.
