Vitamin B12, which is also known as cobalamin, is a water-soluble vitamin required for the production of red blood cells and normal functioning of the brain. It also aids in DNA synthesis and regulation. The vitamin is not produced by your body and since it is water-soluble, it is expelled out of the body through urine when in excess. As your body does not store the vitamin for a longer duration, you need to consume foods that rich in vitamin B12 or supplements. Vitamin B12 is found in animal products like eggs, fishes and meat. The recommended amount of vitamin B12 for adults is 2.4 microgram per day on an average. However, according to a study conducted by Metropolis Healthcare, over 15 percent of the people in India lack the recommended amount of vitamin B12 and most of them are vegetarian.
