WebDietary iron occurs in three major forms: ferrous iron (Fe2+), ferric iron (Fe3+), and heme iron (Fe2+ chelated into a complex organic compound to complete the heme structure, which occurs in hemoglobin, myoglobin, and certain enzymes). Why is heme iron important? It’s used to make red blood cells, which carry oxygen around the body. WebDietary iron occurs in three major forms: ferrous iron (Fe2+), ferric iron (Fe3+), and heme iron (Fe2+ chelated into a complex organic compound to complete the heme structure, which occurs in hemoglobin, myoglobin, and certain enzymes). What is the heme iron? Heme iron is derived from hemoglobin.
