Vitamin B12 (Cyanocobalamin) is an essential cobalt-containing vitamin.
It acts as a coenzyme in two key metabolic pathways: the conversion of methylmalonyl-CoA to succinyl-CoA (important for fatty acid and carbohydrate metabolism) and the synthesis of methionine from homocysteine (crucial for DNA and red blood cell production).
Animal Feed: Added to premixes for swine, poultry, and aquaculture to prevent deficiency, promote growth, and improve feed conversion. Typical inclusion rates are in the range of 0.01-0.05 mg/kg of complete feed, often in combination with other B-vitamins.

Dietary Supplements: Widely used in human multivitamin formulas, B-complex tablets, and sublingual drops at dosages typically between 2.4 - 100 μg per serving.

Pharmaceuticals: Used as an active ingredient in injectable solutions for the treatment of pernicious anemia and B12 deficiency.
