Uses:

See also Precautions section. Cyanocobalamin is a man-made form of vitamin B12 used to prevent and treat low blood levels of this vitamin. Most people get enough vitamin B12 from their diet. Vitamin B12 is important to maintain the health of your metabolism, blood cells, and nerves. Serious vitamin B12 deficiency may result in a low number of red blood cells (anemia), stomach/intestine problems, and permanent nerve damage. Vitamin B12 deficiency may occur in certain health conditions (such as intestinal/stomach problems, poor nutrition, cancer, HIV infection, pregnancy, old age, alcoholism). It may also occur in people who follow a strict vegetarian (vegan) diet.
