Description:

Vitamin B12, abbreviated as VB12, also known as cobalamin, is one of the B vitamins. It is a kind of complex organic compounds of Gulin containing cobalt. The trivalent cobalt is located in the center of the Gulin ring plane similar to porphyrin. It is the largest and most complex vitamin molecule found at present, and it is also the only vitamin containing metal ions; Its crystal is red, so it is also called red vitamin.

Plants do not contain VB12 and cannot make VB12. Liver is the best source of VB12, followed by milk, meat, eggs, fish and so on. VB12 is an essential coenzyme in the synthesis of RNA and deoxyribonucleic acid. The lack of VB12 in vivo can cause pathological changes of nervous system such as peripheral nerve and central encephalopathy.

Application:
  1. It is mainly used to treat various VB12 deficiency diseases, such as megaloblastic anemia, anemia caused by drug poisoning, aplastic anemia and leucopenia; When used in combination with pantothenic acid, it can prevent malignant anemia and contribute to the absorption of Fe2 + and the secretion of gastric acid; It is also used to treat arthritis, facial paralysis, trigeminal neuralgia, hepatitis, herpes, asthma and other allergies, allergic dermatitis, measles, eczema and bursitis; VB12 can also be used for the treatment of neuroticism, irritability, insomnia, memory loss and depression.

  2. New research shows that VB12 deficiency can also cause mental diseases such as depression. VB12 is very safe as a therapeutic agent or health care product. VB12 more than thousands of times RDA was injected intravenously or intramuscularly, and no poisoning was found.

  3. VB12 can promote the growth and development of poultry and livestock, especially young poultry and livestock, and improve the utilization rate of feed protein, so it can be used as feed additive. Treating fish eggs or fry with VB12 aqueous solution can improve the tolerance of fish to toxic substances such as benzene and heavy metals in water and reduce mortality. At present, most of VB12 produced in the world is used in feed industry.
