Description and Uses

Iron, which is the chief constituent of Earth’s core, is the most abundant element in Earth as a whole (about 35 percent) . Ferric pyrophosphate is an iron replacement product, is a mixed-ligand iron complex in which iron (III) is bound to pyrophosphate and citrate. It is widely used to fortify cereal flours and infant cereals, dispersible ferric pyrophosphate is as well absorbed as ferrous sulfate in adults. pyrophosphate ions participate in the ion transfer processes. These ions, as chelating agents, would release iron from transferrin and form a ferric pyrophosphate complex, and that pyrophosphate alone has the ability to mediate iron exchange from transferring to ferritin. Ferric pyrophosphate citrate should only be added to the bicarbonate concentrate; do not add to acid concentrate mixtures. Ferric pyrophosphate citrate is not intended for use in patients receiving peritoneal dialysis; it has not been studied in patients receiving home hemodialysis.

Ferric Pyrophosphate is a nutrient supplement, tan or yellowish white in color, prepared by reacting sodium pyrophosphate with ferric citrate. the ingredient may be used in infant formula. it is also termed iron (iii) pyrophosphate.
