# Vitamin B12 (cyanocobalamin)

Cobalt-containing vitamin (not a peptide)

Cyanocobalamin is the cyanide-bound form of vitamin B12, a cobalt-containing corrinoid. It is a small molecule, not a peptide. Solutions are red and light-sensitive.

Sable Peptides does not stock Vitamin B12 (cyanocobalamin) yet. There is no price, no vial page and nothing to order. This page will say so plainly until a lot with its own Certificate of Analysis is in stock.
