Vitamin B12 - The Nervous System, Anaemia, Learn More

Vitamin B12 is water-soluble, a vitamin that has a vital role in the production of red blood cells, correct functioning of the nervous system, replication of DNA, controling of homocysteine levels when combined with folic acid and vitamin B6 and production of a mood-elevating substance S-adenosyl-L-methionine. Strictly speaking, vitamin B12 is not a single compound; rather it is a collective term referring to a class of cobalt compounds, the principal ones among them being cyanocobalamin, hydroxocobalamin, methylcobalamin and adenosylcobalamin. For that reason, sometimes the term cobalamin is used to refer to vitamin B12.
