Ferrous salts

ferrous sulphate, ferrous fumarate, ferrous gluconate, ferrous lactate, ferrous succinate

These are iron salts with good bioavailability, which usually offer a cheap treatment option for iron deficiency. They exhibit gastrointestinal side effects and partially unpleasant taste. Over‑dosage is possible and can lead to negative effects caused by iron´s toxicity potential (Nagpal & Choudhury, 2004).
