The Origin of Methylcobalamin vs Cyanocobalamin
Vitamin B12 was discovered in the 1940s while studying anemia. Scientists later found different forms of B12.
- Methylcobalamin occurs naturally in animal foods like fish, meat, eggs, and milk. It is one of the active forms used directly by the nervous system.
- Cyanocobalamin is synthetic. It was created because it is stable, cheap, and easy to store.

- Methyl- refers to a methyl group.
- Cyano- refers to a cyanide group (very small and safe in supplements).
