Ferrous fumarate

Ferrous fumarate (CAS 141-01-5), also sold under the trade names Feostat and Ercoferro, is an iron(II) salt used across pharmaceutical, nutritional, and feed industries as a bioavailable source of elemental iron.

Its high iron content and relatively low solubility make it a preferred choice for solid-dose iron supplementation where tolerability and stability are formulation priorities for manufacturers.

In pharmaceutical manufacturing, it is the active ingredient in oral iron deficiency treatments, formulated into tablets, capsules, and chewable dosage forms to ensure effective delivery.

Nutritional supplement producers use it to fortify food products such as breakfast cereals, infant formula, and meal replacement powders where iron enrichment is required for health.

Animal feed compounders incorporate it into premixes and complete feeds to address iron deficiency in livestock and companion animals, supporting overall growth and metabolic health.

In personal care, it functions as a colorant and stabilizing agent in select cosmetic formulations. The material is supplied as a fine reddish-brown powder for easy blending.

It is available in USP, BP, and Ph. Eur. grades for pharmaceutical and nutraceutical applications, as well as feed-grade specifications for animal nutrition.

Technical-grade material is also available for industrial and cosmetic use cases. This ensures that all regulatory and quality requirements are met across various global markets.
