    What is cyanocobalamin made of?
    Cyanocobalamin is a manufactured form of B 12. Bacterial fermentation creates AdoB 12 and MeB 12, which are converted to cyanocobalamin by the addition of potassium cyanide in the presence of sodium nitrite and heat. Once consumed, cyanocobalamin is converted to the biologically active AdoB 12 and MeB 12.
