  • Applications

    Ferrous fumarate (CAS 141-01-5) is used primarily as an iron source in pharmaceuticals and in food fortification, and as a component in dietary supplements. In the pharmaceutical sector, it is used as an oral iron supplement in tablets or liquids. In the food industry, ferrous fumarate is employed to fortify iron in processed foods such as cereals and flour-based products. It is also used in dietary supplements and in specialized nutrition formulas as an iron source for everyday nutrition and for targeted dietary products.
