Ferrous bisglycinate is a chelated iron compound in which Fe(II) is coordinated to glycine ligands. This form is part of the broader family of iron amino acid chelates and is used in a range of supply formulations. In chemical terms, ferrous bisglycinate combines iron with two glycine molecules, creating a stable complex that can be handled in production and formulation processes. With ferrous bisglycinate, the glycine ligands coordinate to the iron center through the amino nitrogen and carboxylate oxygen, generating a chelate structure. This arrangement leads to a discrete three- or five-membered ring depending on coordination geometry and contributes to the overall stability of the compound. Ferrous bisglycinate is categorized as an iron chelate, a class of compounds designed for chemical versatility in pharmaceutical and supplement settings. Manufacturing ferrous bisglycinate typically involves controlled reactions between ferrous sources and glycine under specific pH and temperature conditions, followed by drying and purification steps. The resulting material can be formulated into powders, capsules, or tablets and is used as an iron source in various product categories. Ferrous bisglycinate thus occupies a modular role in chelated mineral formulations. In product labeling and technical specifications, ferrous bisglycinate is described in terms of its chemical composition and chelated nature, with the iron content quantified as elemental iron. The term ferrous bisglycine or ferrous bisglycinate is often used to denote this chelated iron form across industry literature, research references, and formulation notes. For readers exploring this topic, ferrous bisglycinate represents a specific chelate variant within the broader landscape of iron chelates.
