Product Use：
Vitamin B12 is an essential vitamin for the metabolic processes of human tissues. The average total amount of vitamin B12 in the human body is 2-5mg, of which 50-90% is stored in the liver. When the body needs it, it is released into the blood to form red blood cells. Long-term deficiency of B12 can lead to pernicious anemia. B12 and folic acid are important coenzymes in the process of cellular nucleic acid synthesis, participating in the synthesis of purines, pyrimidines, nucleic acids, methionine, etc.; they can also transfer methyl groups to promote the synthesis of choline; at the same time, they can increase the synthesis of glycogen, thereby having the effect of eliminating liver fat. It is often used clinically as a drug for treating liver diseases. The human body needs about 1 microgram of vitamin B12 per day, and if the daily food can provide 2 micrograms, it can meet the normal needs. Hydroxocobalamin in vitamin B12 can react with cyanide to form cyanocobalamin, thereby eliminating the toxicity of cyanide. Therefore, people with vitamin B12 deficiency are more sensitive to cyanide than the average person. Vitamin B12 is mainly used to treat pernicious anemia, megaloblastic anemia, anemia caused by antifolate drugs, and polyneuritis, etc.
A deficiency in vitamin B12 can lead to anemia and neurological disorders. It can be used in infant food with a dosage of 10–30 μg/kg; and in fortified beverages with a dosage of 2–6 μg/kg.
It is mainly used for the treatment of megaloblastic anemia, nutritional deficiencies, hemorrhagic anemia, neuralgia, and obstructive diseases.
As a feed nutritional fortifier, it has the effect of anti-anemia and is effective for pernicious anemia, nutritional anemia, and parasitic anemia. The dosage is 15-30mg/t.
