Iron syrup is a liquid dietary supplement, typically used to treat and prevent iron deficiency and anemia, especially in individuals with increased iron requirements like pregnant women, children, and athletes. It helps the body produce red blood cells, which carry oxygen, and can improve energy levels and reduce fatigue. Commonly formulated with ferrous salts (like ferrous sulfate or ferrous gluconate) and often includes vitamins like B12 and folic acid to enhance absorption and overall efficacy.
