Methylcobalamin has a methyl group (just carbon and hydrogen) while cyanocobalamin contains a cyanide molecule. Although the amount of cyanide in a normal B12 supplement is too small to be harmful, your body will still need to remove and eliminate this compound. As it has no use for the cyano-compound itself, it will set about converting any cyanocobalamin you take into methylcobalamin as soon as possible - it’s the methyl-compound that the human body needs to function properly.
Methylcobalamin the most bio-available form of Vitamin B12, i.e. it is the most readily absorbed. Further to this research has shown that it remains in the body for a longer period of time and at higher levels than cyanocobalamin, which means that your body is supplied with vitamin B12 for longer if you use methylcobalamin than if you use cyanocobalamin.
