Yet the consequences are unknown Bioavailability: there are four specific metabolic steps necessary to convert cyanocobalamin into one of the coenzyme forms, which is a clear metabolic disadvantage (3) Utilisation problems: certain hereditary diseases, as well as metabolic disorders, prevent the conversion of cyanocoalamin into the active B12 forms (4) Steals methyl groups: cyanocobalamin requires a methyl group to convert into methylcobalamin, which it takes from the important amino acid S-adenosylmethionine (SAM)
