Vitamin B12 (cobalamin)

Identity insufficiently defined

Grade describes the published research on the molecule. It is not a quality score, a safety score, or a release state.

What this is

Cobalamin exists in several forms — cyanocobalamin, methylcobalamin, hydroxocobalamin — which are not interchangeable for identity purposes.

Evidence position

Grade U until form and concentration are documented. An official cyanocobalamin label is a comparator, not evidence about a given product.

What the record does not establish

Published research about a molecule is not a test of any particular vial. Identity, purity, strength and microbiological quality are established by lot-level analytical records tied to a matched sample — not by the literature, and not by the presence of an approved comparator.

Where a lot-level record exists it is published on the evidence page and linked from the product. Where it does not exist, the record says so.
