The liver is the best source of VB12, then from milk, meat, eggs, fish and so on.VB12 is an essential coenzyme in the synthesis of RNA and DNA.

Chronic lack of B12 can cause pernicious anemia. B12 and folic acid are important  fear of enzymes during cell nucleic acid synthesis, involved in the synthesis of purines, pyrimidines, nucleic acids and methionine; and allows methyltransferase to promote the synthesis of the base; at the same time to increase the synthesis of sugar yuan, thus eliminating the role of liver fat. Clinical often as a drug for the treatment of liver diseases. Human need vitamin B121 micrograms per day, every day foods provide 2 micrograms, to ensure the normal needs.
