Vitamin B12 Foods


Vitamin B12 is a B complex vitamin that contains cobalt and hence is also known as cobalamin. This vitamin plays a major role in formation of red blood cells and maintaining a healthy nervous system. It is also necessary for the rapid synthesis of DNA during cell division.

Vitamin B12 help in rapid ‘synthesis of DNA’ at the time of cell division – a process that holds high importance in bone marrow tissues which are responsible for the formation of red blood cells.Hence vitamin B12 deficiency leads to abnormal DNAs and leads to formation of abnormal cells named megaloblasts. The nervous system is insulated by a fatty sheath called myelin sheath.

Vitamin B12 has a major role in metabolizing the fatty acids which are essential for maintaining the myelin sheath in good condition. Thus vitamin B12 deficiency can results in degeneration of nerves and irreversible neurological damage.

Vitamin B12 is synthesized by bacteria and hence is naturally available from animal products such as milk, egg, meat etc. There is no risk in consuming excess vitamin B12 as that which isn’t absorbed will either be stored in the liver up to one year for future use, or excreted.
