What does it do?

Iron(II) fumarate is a form of iron, a mineral component used to supply iron in the body. It is primarily included in vitamins or mineral preparations for the prevention and treatment of anemia. Iron plays an essential role in the transportation of oxygen in the blood.

Iron(II) fumarate is absorbed as iron in the body and contributes to the production of hemoglobin in the blood. Hemoglobin carries oxygen from the lungs to the entire body, alleviating symptoms of anemia. Therefore, it helps improve fatigue and weakness due to iron deficiency.
