However, the body is known to store this Vitamin in the liver for years at an end. Vitamin B12 like all the other B Vitamins is very crucial for the metabolism process of the body. Vitamin B12 is also helpful for the formation of the new blood cells as well as maintaining the CNS (Central Nervous System).
