Ferrous iron

Fe2+

Ferrous iron is the soluble, divalent oxidation state of iron, which is easily absorbed by the human body and therefore plays an important role in iron homeostasis (Yiannikourides & Latunde-Dada, 2019, Abbaspour et al., 2014). At physiological pH, it is oxidised to ferric iron (Fe3+)(Abbaspour et al., 2014).
