Vitamin B12 is part of the vitamin B complex, and lack of it affects our metabolism. Vitamin B12 is also important in helping to form red blood cells, which carry oxygen throughout the body, and in maintaining the nervous system.
Vitamins fall into two general categories. The first are called fat-soluble vitamins and include vitamins E and K, among others. These vitamins can be stored in the body and, in some cases, produced by the body, so deficiency is very rare. However, vitamin B12 is a water-soluble vitamin. While is can be stored in the liver, only small amounts can be stored this way, and it takes a long time to build up a store of Vitamin B12 in the liver. Therefore, a daily intake is very important.
Balanced Diet
As with most vitamins, the best way to get vitamin B12 into your body is through a balanced diet. If you eat a healthy, balanced diet, you will already be taking in all the Vitamin B12 you require. However, if you have special dietary needs or medical conditions, vitamin supplements may be needed. High levels of vitamin B12 can be found in eggs, poultry, beef, pork, shellfish, and dairy products, especially milk.
