Ferrous ascorbate and folic acid capsules are used to treat and prevent iron deficiency anemia and folate deficiency anemia, supporting red blood cell production and hemoglobin levels. The ferrous ascorbate provides iron for oxygen transport, while folic acid helps form red blood cells and is crucial for a baby's brain and spinal cord development during pregnancy. This combination is especially beneficial for pregnant women, after surgery or blood loss, and for people with poor diets or chronic illnesses.
