Ferric citrate, a complex iron supplement, comes in a variety of shades depending on its composition. It typically ranges from a greenish brown to a reddish-brown powder, with some variations like orange or even garnet red being possible. Unlike some iron supplements, ferric citrate is odorless. Notably, ferric citrate is hygroscopic, meaning it attracts moisture from the air. This can cause the powder to clump or cake over time, so proper storage in a sealed container is recommended. Texture-wise, ferric citrate is usually a fine powder, although some variations might be slightly granular. It is formed by the bonding of ferric ions (Fe3+) with citrate, a molecule derived from citric acid. This interaction creates a coordination complex, where the citrate molecule acts as a ligand, donating electron pairs to the central iron ion.

The specific structure of the complex can vary depending on the ratio of ferric ions to citrate molecules, but most commonly, a single ferric ion binds to multiple citrate ligands. This complexation with citrate enhances the solubility of iron in water compared to ferric salts like ferric chloride, making ferric citrate a bioavailable form of iron for dietary supplements and medications. Ferric citrate API can be formulated into various dosage strengths and delivery forms (e.g., tablets), catering to individual patient needs and treatment preferences.
