Ascorbic Acid / Ferrous Gluconate / Vitamin B12
This is a combination supplement containing iron, vitamin C (ascorbic acid), and vitamin B12 used primarily to treat or prevent iron deficiency anemia. The formulation is designed so that vitamin C enhances iron absorption in the digestive tract while B12 supports healthy red blood cell production. It is commonly prescribed for patients with anemia, those with increased iron needs such as pregnant individuals, or people with conditions affecting nutrient absorption.
A multi-ingredient supplement combining iron, vitamin C, and B12 used to treat iron deficiency anemia by supporting hemoglobin production and enhancing iron absorption.

Treatment and prevention of iron deficiency anemia, general iron deficiency states, and conditions with increased iron requirements such as pregnancy, adolescence, or recovery from blood loss. May also be used for patients with malabsorption syndromes affecting iron or B12 uptake.
Ferrous gluconate provides elemental iron for hemoglobin synthesis and red blood cell production. Ascorbic acid acts as a reducing agent to convert ferric iron to the more absorbable ferrous form and creates an acidic environment that enhances iron uptake in the gastrointestinal tract. Vitamin B12 (cobalamin) supports DNA synthesis in red blood cell precursors and proper red blood cell maturation.
Should be taken on an empty stomach with water or juice for optimal absorption. May cause gastrointestinal upset, constipation, or dark stools. Avoid taking with calcium, antacids, or dairy products as they can significantly reduce iron absorption. Oral iron supplements can interact with certain antibiotics (tetracyclines, fluoroquinolones), thyroid medications, and proton pump inhibitors. Some individuals may require periodic monitoring of iron studies and B12 levels.
