Vitamin B-12 is the most chemically complex of all the vitamins and is the general name for a group of essential biological compounds known as cobalamins. Cobalamins are similar to hemoglobin in the blood except that instead of iron they contain Cobalt.



Vitamin B12 is needed to prevent anemia, it aids folic acid in regulating the formation of red blood cells, and helps in the utilization of iron. B12 is essential in converting Homocysteine into Methionine, which is used to build protein. It is also required for proper digestion, absorption of foods, and the metabolism of carbohydrates and fats. It aids in the cell formation and cellular longevity. Vitamin B12 prevents nerve damage and is needed for making use of protein, and helps the blood carry oxygen. It maintains fertility, and promotes normal growth and development by maintaining the fatty sheaths that cover and protect nerve endings. A study reported in the American Journal of Obstetrics and Gynocology in 2004 found that women who gave birth to children with Spina bifida had vitamin B12 levels that were 21 percent lower than those of mothers who had healthy children. Vitamin B12 is also linked to the production of Acetylcholine, a neurotransmitter that assists memory and learning.



A deficiency in B12 can be caused by malabsorption, which is most common in older adults and in people with digestive disorders. Vegetarians must remember that they require Vitamin B12 supplements, as this vitamin is found exclusively in animal tissue. Although Vegetarians may not see signs of deficiency for a while—the body can store up to five years’ worth of Vitamin B12, but signs will eventually develop. For those who have followed a vegetarian diet for more than 5 years should have their B12 blood levels checked annually.

Supplementation is necessary! The most common and inexpensive form of Vitamin B12 is Cyanacobalamin which is difficult for the body to absorb, as a result people taking this form of B12 continue to be deficient in the vitamin and will have to resort to B12 injections. The most effective form is Methylcobbalamin. Therefore it is wise to take Methylcobalamin in the first place either swallowed in tablet form or sublingually. Those with severe digestive disorders may have no choice but to resort to vitamin B-12 injections.
