It plays an essential role in the production of your red blood cells and DNA, as well as the proper functioning of your nervous system.

Vitamin B12 Injection [Cyanocobalamin]
Cyanocobalamin, or vitamin B12, is a B-vitamin. It is found in a variety of foods such as fish, shellfish, meats, and dairy prod- ucts. Deficiency in healthy individuals is rare; the elderly, strict vegetarians (i.e., vegan), and patients with malabsorption prob- lems are more likely to become deficient. If vitamin B12 deficiency is not treated with a vitamin B12 supplement, then anemia, intestinal problems, and irreversible nerve damage may occur. Oral therapy is not always effective, as some persons lack in- trinsic factor, an endogenous substance produced by the stomach and necessary for oral B12 absorption.
Methylcobalamin, or vitamin B12, is a B-vitamin. It is found in a variety of foods such as fish, shellfish, meats, and dairy prod- ucts. Although methylcobalamin and vitamin B12 are terms used interchangeably, vitamin B12 is also available as hydroxoco- balamin, a less commonly prescribed drug product (see Hydroxocobalamin monograph), and methylcobalamin. Methylcobala- min is used to treat pernicious anemia and vitamin B12 deficiency, as well as to determine vitamin B12 absorption in the Schil- ling test.
