Iron is one of the essential trace elements in human and animal body, and the production of heme, myoglobin and cytochrome must depend on iron. Iron is also a component of enzymes (catalase), non-heme iron (NHI) and thioproteins (succinate dehydrogenase) and an inorganic cofactor of other enzymes. The content of iron in normal human body is 35 ~ 60 mg/kg, of which 70% exists in hemoglobin, 3% ~ 5% exists in myoglobin, 15% exists in iron storage proteins - ferritin and hemosiderin. The absorption and conversion efficiency of different forms of iron in the animal body is also different, and ferrous sulfate is cheap and occupies a certain advantage, but it is easy to absorb moisture, poor taste, low absorption efficiency, easy to cause waste and environmental pollution. Organic iron sources such as iron glycine, ferrous glutamate, ferrous methionine and ferrous aspartate are getting more and more attention because of their advantages such as high biological potency, high absorption rate and beneficial to environmental protection.
