What ingredients are in cyanocobalamin?

Cyanocobalamin is a synthetic form of vitamin B12, primarily composed of the vitamin itself, which contains a cobalt ion at its core. It typically includes a cyanide group, which is what distinguishes it from other forms of B12. In its commercial form, cyanocobalamin may also contain excipients like lactose, starch, or preservatives, depending on the formulation (e.g., tablets, injections). However, the primary active ingredient is the cyanocobalamin compound itself.
