Vitamin B12 is also called cobalamin, vitamin B12 is synthesized by microorganisms in nature, and higher plants and animals cannot produce vitamin B12. Vitamin B12 is the only vitamin that needs the help of intestinal secretions (endogenous factors) to be absorbed. Some people have abnormal stomach and intestines, so they lack this endogenous factor, and even if they eat an adequate diet, they will suffer from pernicious anemia.
There is almost no vitamin B12 in plant-based foods. It stays in the intestines for a long time, taking about 3 hours (most water-soluble vitamins only take a few seconds) to absorb.
What is the role of vitamin B12?
<>1.Improve the utilization rate of folic acid, in the process of synthesizing folic acid to synthesize methionine (from gostin) and cobalamin such as choline, methylcobalamin and coenzyme B12, make purines and peptides, participate in the methylation process of many important compounds. Vitamin B12 deficiency reduces the activity of methyltetrahydrofolate to transfer methyl groups, making folate an unusable form, leading to folate deficiency.
2. Maintain the metabolism and function of the nerve myelin sheath. Vitamin B12 deficiency can cause neurological disorders, spinal cord degeneration, and severe psychiatric symptoms. Vitamin B12 deficiency can cause peripheral neuritis.
Early symptoms of vitamin B12 deficiency in children are mood disturbances, sluggish expressions, unresponsiveness, and eventually anemia.
3. Promote the development and maturation of red blood cells. Methacrylic acid-Coa is converted to succinic acid-CoA, which participates in the tri-acid cycle, of which succinate-CoA is involved in the synthesis of hemoglobin.
4. Vitamin B12 is also involved in the synthesis of deoxyribonucleic acid (DNA), the metabolism of fats, carbohydrates and proteins, and increases the synthesis of nucleic acids and proteins.

It can promote the development and maturation of red blood cells in the body, especially when taken with folic acid, it can fully improve the utilization rate of folic acid and is used for megaloblastic anemia. Second, it can also enhance brain memory and promote brain metabolism to participate in the synthesis of neurotransmitters, so it can be used for Alzheimer's disease.
