  • Applications

    Ferrous glycinate (CAS 20150-34-9) is an iron(II) chelate with glycine, primarily used as an iron nutrient source in animal feeds and as an ingredient in human dietary supplements. It is also employed in food processing and fortification as an iron supply with potential advantages in bioavailability and reduced mineral interactions. In agriculture, it can serve as a micronutrient source for fertilizers or crop nutrition via foliar or soil applications. As a metal chelate, Ferrous glycinate may be used as an intermediate in industrial chelation systems and in formulations requiring a stable iron source with controlled release. Uses depend on local regulations and formulation limits.
