Health and Nutrition

Vitamin B12 is a water-soluble essential vitamin. In its molecule is an atom of cobalt and hence the name cobalamin. It has an important role to play in the body, it is required for DNA synthesis and for maintaining nerve myelin sheath.


Role of vitamin B12 in our body and the importance of vitamin B12 rich foods in our diet:

Vitamin B12 is very important for the appropriate utilization of folate in the body. If vitamin B12 is deficient in the body it can lead to folate deficiency too. Because of vitamin B12, folate requirement is kept at the level we right now are recommended, otherwise, the amount of folate we need would be much higher.

It is also required in the metabolism or breakdown of certain amino acids and fatty acids. 

Vitamin B12 plays a vital role in the maintenance of the myelin sheath that serves as an insulation for nerve cells. The speed with which the nerve impulses are passed depends on this myelin sheath.

Vitamin B12 also plays a critical role along with other B vitamins in homocysteine metabolism. In the case of vitamin B12 deficiency, elevated levels of homocysteine are seen in blood. And elevated homocysteine levels are linked to cardiovascular issues and hence the need for vitamin B12 rich foods or supplements.

RDA of vitamin B12 is 2.4 µg a day for healthy adults. The RDA during pregnancy increases to 2.6 µg and during lactation to 2.8 µg.
