Details

What it is

A corrinoid vitamin built around a cobalt ion, the largest and most structurally complex vitamin known. Not a peptide. The cyanocobalamin form supplied here is the stable synthetic form, converted in the body to the active methyl and adenosyl forms.

Also sold as: cyanocobalamin, cobalamin, B-12

Supplied in solution, so there is nothing to reconstitute. Ranges rather than dates, because stability depends on the solvent and the container and we have not tested this material — see storage and stability.

What you receive differs from the figures above. Figures are for cyanocobalamin itself. Supplied as a solution, so the vial contents are not pure substance.
