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)
Glycemic control: In type 2 diabetes patients, HbA1c dropped by 1.32.0% (from ~8.0% to ~6.0%) with 412 mg doses [1]

Long-Term Data: While short-to-medium term studies (up to several months) indicate safety, long-term safety data (over multiple years) in broad populations is still being gathered
