2. What Is Vitamin B12 (Cobalamin)?
Vitamin B12, also known as Cobalamin, is a water-soluble B-complex vitamin widely used as a functional ingredient in dietary supplements, fortified foods, and pharmaceutical formulations. It is commonly supplied in stable synthetic forms such as Cyanocobalamin and bioactive forms like Methylcobalamin, depending on formulation needs.
From an industrial perspective, Vitamin B12 is valued for its functional nutritional role, formulation stability, and compatibility with a wide range of dosage forms including tablets, capsules, powders, liquids, and injections (non-medical ingredient use only).
