Vit B-12 (also known as cyanocobalamn) should be plentiful in most of our diets but the body’s ability to utilize it is often impaired, especially as we age. 20% of elderly people are thought to be deficient in vitamin B-12 even if many of them have no overt symptoms. Supplements are therefore often recommended with advancing age. It has been known to cure pernicious anaemia which can be a potentially fatal disease affecting older adults in particular. Vitamin B-12 is the only B vitamin that the body stores in large amounts, mostly in the liver. It is usually taken in conjunction with folic acid.
How it works and benefits:
The body absorbs Vitamin B-12 through a very complicated process. It binds to protein in food. Digestive enzymes in the presence of enough stomach acid, that is hydrochloric acid, separate it from the protein in foods and so it is released. Once released, vitamin B12 combines with a substance called intrinsic factor (IF), a protein produced by cells in the stomach lining, before being carried to the small intestine, where it is absorbed. This compound can then be absorbed by the intestinal tract.
Low levels of stomach acid or an in adequate amount of IF both of which occur with age and in other conditions can lead to deficiencies. Because the body has good reserves of Vit B-12, it can take several years for a shortfall to develop.
Vit B-12 is essential for cell replication and is particularly important for red blood cell production. It maintains the protective sheath around nerves (myelin), assists in converting food to energy and plays a critical role in the production DNA and RNA, the genetic material in cells.
The RDA is 1 mcg per day for adults and children over the age of 10. Many recommend that we get 100 to 400 mcg daily. Initially if extremely exhausted or severe conditions 4 tablets per day can be used which can be reduced to 1 per day and then phased out.
