These two different B12 forms are very similar. The only chemical difference between them comes down to one small part of the molecule, Methylcobalamin has a methyl group (just carbon and hydrogen), cyanocobalamin has a cyanide group. And obviously cyanide isn't something you normally expect in anything you would consume. In fact, cyanocobalamin isn't something nature ever intended your body to deal with – it exists only as a chemical synthesized in laboratories. It doesn't occur naturally in any living organism.

Cyanocobalamin is a less efficient way to supplement your vitamin B12 intake. You also face the problem of what happens to the cyanide group that is liberated during conversion into the ‘active' (useful) form of B12 i.e. Methylcobalamin. Cyanide is of course famous for being a poison, so your body needs to remove this unwanted substance. It's probably fair to say that most people would prefer not to start deliberately ingesting cyanide!

Cyanocobalamin is cheaper for manufacturers to buy...that's why they use it, despite it being unhealthy for the consumer - YOU! So anytime you pick up an energy product or dietary supplement - take a quick look at the ingredients and make sure you avoid all products that say "cyanocobalamin" in them.
