The main benefit of ferrous sulfate is for the treatment of iron deficiency anemia and its symptoms. Ferrous sulfate, which is a form of iron, is the generic name for different types of iron supplements, notes eMedicineHealth. When a patient with iron deficiency anemia takes ferrous sulfate, it provides the iron needed by the body so it can manufacture new red blood cells.
The body gets its iron mainly from diet. The recommended daily intake of iron can vary due to age and gender. Adolescent and adult males require 10 milligrams of iron a day, while females in this same age group can require 10 to 15 milligrams of iron, states Mayo Clinic.
However, when a patient has iron deficiency anemia, supplementation with ferrous sulfate iron tablets can supply the body's requirement for iron and facilitate the production of red blood cells. Iron deficiency anemia is a condition in which the body does not have sufficient red blood cells. Red blood cells are important because they carry oxygen throughout the body through blood vessels.
As a result of iron deficiency anemia, symptoms that may develop are feeling tired, breathing problems and infections, according to Mayo Clinic. In mild cases of iron deficiency anemia, it can take a few days for symptoms to get better with ferrous sulfate iron supplementation. In more severe cases of this condition, it can take up to 6 months for improvement in symptoms, states the National Institutes of Health's MedlinePlus.
