Effects of Iron amino acid chelate on animal absorption

Many studies have shown that animals have better bioavailability of iron glycine chelate, and the better biological titer of iron glycine chelate may be related to the absorption mechanism in animals. The absorption of exogenous iron mainly occurs in the duodenum and upper jejunum, and requires the assistance of related membrane transporters. Divalent Metal Transporter 1 (DMT1) can transport intestinal divalent metal ions, including Fe2+, into cells, mainly at brush margins and crypts of duodenal villi. The change of its expression is mainly regulated by the feedback mechanism of sensing iron storage in vivo. Ferroportin 1 (Fpn1) is responsible for transporting iron from cells into the blood. Phytic acid, cellulose and other anti-nutrient factors can react with ferrous ions in the intestine to form insoluble complexes, thus affecting the absorption of iron ions in the intestine. The iron element in amino acid chelate iron can avoid the influence of phytic acid and cellulose because of chelating with amino acid ligand, so as to obtain better absorption effect. In the Caco-2 cell model, iron ascorbate and iron amino acid chelate have similar iron absorption mechanisms, both of which are absorbed by DMT1 in the cell in the form of iron ion.
