Pharmacology
Mecobalamin is one of the two active forms of vitamin B12 in the body. Unlike cyanocobalamin, it carries a methyl group in place of the cyano group attached to its cobalt atom. It acts as a cofactor for the enzyme methionine synthase, which transfers methyl groups to convert homocysteine back into methionine. This function makes it essential for maintaining the myelin sheath, supporting normal nerve activity, forming red blood cells properly, and synthesizing DNA. Mecobalamin also supports the production of lipids needed by nerve cells, aids in regenerating axonal nerves, promotes axonal transport, and provides protective effects for the nervous system.
