                                A 2024 review in StatPearls noted that once absorbed, cyanocobalamin is converted in tissues into a cofactor for various metabolic processes. Most widely used in supplements and fortified foods due to its stability, cyanocobalamin breaks down into the two metabolically active forms of vitamin B12: methylcobalamin and adenosylcobalamin.
