Ferrous bisglycinate

Ferrous bisglycinate contains 20% elemental iron, is highly bioavailable, water soluble and shows low potential to induce changes in food through oxidation (Prentice et al., 2017). One molecule of ferrous iron (Fe2+) is chelated to two molecules of the amino acid glycine. Iron is bound to the carboxyl group of the glycine molecules via an anionic bound, forming two heterocyclic rings (Allen, 2002).

Ferrous bisglycinate can be used for iron supplementation in infants, men, non-pregnant and pregnant women without any safety concerns (EFSA NDA, 2006).

Synonym: iron bisglycinate
