Vitamin B12, also known as cobalamin, is a water-soluble vitamin that helps perform numerous biological functions in the body. It is found in trout, salmon, tuna, yoghurt, beef, soybeans, tofu, milk, cheese, egg, chicken, ham, cheeseburger, fruits and leafy green vegetables. The recommended dietary allowance for vitamin B12 for adults is 2.4 micrograms.
Vitamin B12 is necessary for protein, carbohydrate and fat metabolism. It is needed for the calcium absorption and helps in the formation of red blood cells. It helps maintain a healthy nervous system and promotes growth in children. Moreover, it helps in the DNA synthesis and is required for the conversion of homocysteine to methionine. High levels of homocysteine may lead to cardiovascular disease particularly atherosclerosis and congestive heart failure.
