Treatment and prevention of iron deficiency anemia, including anemia from pregnancy, poor nutrition, blood loss, or malabsorption conditions. Also used for general iron and B-vitamin supplementation when dietary intake is insufficient.
Ferrous fumarate provides elemental iron, a critical component of hemoglobin. Ascorbic acid (vitamin C) converts iron to a more absorbable form and enhances its uptake in the intestines. Vitamin B12 (cobalamin) supports red blood cell production and nerve health, often depleted in anemia cases.
Take with food to minimize stomach upset, though absorption is best on an empty stomach if tolerated. Avoid taking with calcium, antacids, or dairy products as they reduce iron absorption. May cause dark stools or constipation. Iron overdose can be dangerous, especially in children—store securely. Oral iron can reduce absorption of certain antibiotics and thyroid medications; space doses accordingly.
