Ferrous bisglycinate, identified by CAS number 20150-34-9, is a high-quality iron chelate consisting of one ferrous ion coordinated with two molecules of the amino acid glycine. This chemical structure forms a stable, electrically neutral complex that protects the iron from reacting with other dietary components or oxidizing prematurely. It typically appears as a fine, free-flowing powder that exhibits excellent solubility in water, making it a versatile ingredient for various liquid and solid formulations.
In industrial and research contexts, this compound is valued for its superior stability and reduced reactivity compared to traditional inorganic iron salts. The chelation process ensures that the iron remains sequestered until it reaches the intended site of action, minimizing the metallic taste and oxidative degradation often associated with iron supplementation. Proper storage in a cool, dry environment is essential to maintain its integrity, as the material is sensitive to moisture and light.
