Cyanocobalamin · methyl-donor / metabolic adjunct
Overview
Vitamin B12 (cobalamin) refers to a family of water-soluble cobalt-containing compounds built around a corrin ring that chelates a central cobalt ion. The four core forms are cyanocobalamin, methylcobalamin, hydroxocobalamin, and adenosylcobalamin (cobamamide). Cyanocobalamin is the synthetic, chemically most stable form and the most common commercial raw material; methylcobalamin and adenosylcobalamin are the two physiologically active coenzyme forms in the body; hydroxocobalamin is the natural intermediate form and is also the active ingredient in Cyanokit, the FDA-approved cyanide poisoning antidote (approved… Vialdyne supplies Vitamin B12 (Cyanocobalamin) as dark red crystalline powder with a batch-specific Certificate of Analysis covering identity, assay, and appearance. Each lot is released only against its documented specification.
Applications & buyer fit
Buyers for longevity-class peptides span research labs working on telomere, collagen, and circadian-rhythm models, plus cosmetic-formulation OEMs incorporating peptides like GHK-Cu into anti-aging finished products. Copper peptides in particular require attention to chelator-free water and EDTA-free buffers in downstream formulation work, incompatibility there is the most common cause of "the peptide didn't work" support tickets in this class.
