Ferrous bisglycinate, a well-tolerated iron supplement, boasts unique physical and chemical properties. It is light to dark greenish powder with occasional friable lumps and virtually no odor. Interestingly, this powder is non-hygroscopic, meaning it won’t readily absorb moisture from the air, enhancing its stability. On touch, ferrous bisglycinate has a slightly gritty texture due to its crystalline structure. Delving deeper, science reveals ferrous bisglycinate’s fascinating chemical makeup. It’s classified as a chelate, where two glycine molecules (the simplest amino acid) bond with a central ferrous iron (Fe+2) ion.

This bond creates a ring structure, improving iron’s bioavailability and reducing potential stomach upset compared to other iron supplements [1]. The chemical formula for ferrous bisglycinate is C₄H₈FeN₂O₄, offering a glimpse into its atomic composition. With its distinct properties, ferrous bisglycinate stands out as a valuable form of iron for dietary supplementation. As a leading API manufacturer, WBCIL prioritizes strict CGMP and ISO quality control measures throughout the production process. We offer a completely chelated structure confirmed by FTIR test. The prolonged experience from 1962 ensures consistent potency, purity, and safety in every dose of WBCIL’s ferrous bisglycinate.
