Proferrin is a brand name for a specific type of iron supplement known as heme iron polypeptide. Heme iron is a form of iron that is derived from animal sources, particularly red blood cells, and is considered highly bioavailable and easily absorbed by the body.
Proferrin, or heme iron polypeptide, is often used as a dietary supplement to address iron deficiency or iron-deficiency anemia. Iron deficiency occurs when there is an insufficient amount of iron in the body, leading to symptoms such as fatigue, weakness, pale skin, and difficulty concentrating. Iron-deficiency anemia is a more severe form of iron deficiency characterized by low levels of red blood cells and reduced oxygen-carrying capacity.
