NCIt 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.;
