203.98, properties: light yellowish-brown green crystalline powder, stable, long-term storage unchanged. No general iron agent of iron smell, is odorless soluble organic iron, easily soluble in water. Can avoid phytic acid to general iron absorption obstacles, its absorption rate is about 3-5 times of ferrous sulfate, still can promote the absorption of calcium, zinc, selenium and other elements, will not lead to food discoloration or flavor. Physiological function: Improve iron deficiency anemia. Ferrous glycinate is a nutritional feed additive, which provides an efficient, safe and simple way to prevent and control animal anemia, obtain the best immune level and healthy growth in feed. Compared with the first generation (inorganic ferric acid salt) and the second generation (organic ferric acid salt), ferrous glycine has the characteristics of good stability, easy absorption, no iron odor, no gastrointestinal irritation, non-toxic side effects, high bioavailability, is the latest generation of iron supplement additive, can supplement iron and glycine for livestock and poultry at the same time, improve animal palatability. General iron must be digested or dissociated in the digestive tract before being absorbed. Dissociated iron is easy to cause some gastrointestinal side effects, such as constipation and acute abdominal pain, and even nausea in severe cases; Iron through the stomach will also combine with hydrogen sulfide in the intestine to form black iron sulfide precipitation, forming black feces excretion, not only the absorption rate is low, but also due to the reduction of hydrogen sulfide content in the intestinal cavity, reduce the stimulation of hydrogen sulfide on the intestinal wall, causing constipation problems. Ferrous glycine does not dissociate in the stomach, does not have the side effects of common iron agents, has very low toxicity, high safety, stable activity, can maintain chelate state through the stomach, to the small intestine is absorbed, does not stimulate the stomach and does not cause constipation.Relative molecular mass: 203.98 Properties: Light yellowish-brown green crystalline powder, stable, long-term storage unchanged. No general iron agent of iron smell, is odorless soluble organic iron, easily soluble in water. Can avoid phytic acid to general iron absorption obstacles, its absorption rate is about 3-5 times of ferrous sulfate, still can promote the absorption of calcium, zinc, selenium and other elements, will not lead to food discoloration or flavor. Physiological function: Improve iron deficiency anemia. Preparation method: Obtained by the reaction of glycine and reduced iron.
