Chronic diseases often result in iron deficiency anemia, typically treated with oral non-heme iron that has low absorption rates and significant side effects. Intravenous iron therapy is an alternative but carries risks of allergic reactions and oxidative stress. Heme iron supplementation offers a more effective solution, with better absorption, fewer side effects, and a user-friendly dosage, exemplified by Ferrocare's Optifer® tablets made from natural bovine heme iron.
