Iron is one of the necessary trace elements of animals’ body. It is the formation of heme, myoglobin, cytochromes and other components.Iron have a great correlation with animal hematopoiesis, carrying oxygen, capacity and other processes . Animals require the action of purines in the synthesis of somatic proteins, and iron is an essential substance in the synthesis of purines. When animals are deficient in iron, the first manifestation is slow growth, weak disease resistance, reduced feed utilization, poor reproductive performance, followed by anemia, diarrhea, and death.

Ferrous fumarate, also known as Fumaotu, is a safe and effective organic nutritional iron supplement that belongs to organic acid iron (including: iron lysine, iron glycine, iron methionine, etc.).Its organic divalent iron content is up to 30% or more, when ferrous fumarate is absorbed, ferrous ions are easier to break down into the red blood cells without additional energy.It does not stimulate the stomach and can improve and maintain the normal heme Level.Ferrous fumarate can be used as long-term nutritional supplement. In terms of clinical treatment,it is used to treat iron deficiency anemia.

Ferrous fumarate is absorbed in the upper body duodenum and jejunum in the form of ferrous ions.The majority of absorbed iron is involved in the synthesis of hemoglobin in the bone marrow and the remainder is stored in the reticuloendothelial cells of the bone marrow, liver and spleen in the form of ferritin and hemosiderin,another part exist in intestinal mucosal cells.This absorption method is different from the inorganic iron supplements (ferrous sulfate, ferric carbonate and iron oxide, etc.), it can ease the absorption of trace elements in the competitive antagonism and will not destroy vitamins. It will not catalyze the oxidation reaction.
