However, ferrous gluconate contains less elemental iron than ferrous sulfate, so a greater dosage may be needed to correct a deficiency. Iron administered parentally increases hemoglobin levels to a greater extent and is associated with fewer side effects than oral iron supplementation in patients with anemia of chronic disease [86]. Although iron deficiency is the most common cause of anemia, deficiencies of other micronutrients (such as folate and vitamin B12) and other factors (such as chronic infection and inflammation) can cause different forms of anemia or contribute to their severity.
