Vitamin B12 or cyanocobalamin is a water soluble vitamin that can be found in fish, meat and dairy products. This vitamin is associated with elevations in energy, and hence is sometimes called the energy vitamin. Vitamin B12 injections usually are recommended for treating deficiencies of vitamin B12 due to pernicious anemia, malabsorption syndromes, or a strict vegetarian diet.
