Mechanism of action

Iron deficiency anemia results from insufficient iron for red blood cell production. Ferrous fumarate is an iron salt that delivers ferric iron to the gastrointestinal tract for absorption. Ascorbic acid (vitamin C) acts as a reducing agent and chelating agent, improving ferrous iron bioavailability and absorption efficiency in the intestine.
