Ferrous lactate, or iron(II) lactate, is a chemical compound consisting of one atom of iron (Fe2+) and two lactate anions. It has the chemical formula Fe(C3H5O3)2.


It is used as a food additive with E number E585. It is an acidity regulator and colour retention agent, and is also used to fortify foods with iron.


It is toxic and may cause irritation. Avoid inhalation of dusts. Remove all contamination, rinse with plenty of water. May cause some health symptoms including nausea after ingestion both acute and delayed.[1]
