Methylcobalamin Information & Coordination for Licensed U.S. Clinics
Methylcobalamin is a form of vitamin B12 with a different FDA regulatory record from cyanocobalamin.
Phoenix Meds Inc. supports licensed U.S. healthcare organizations with clinic verification, documentation organization, access to publicly available regulatory information, and administrative pharmacy coordination with independent licensed pharmacies.
For clinics reviewing a methylcobalamin inquiry, the specific B12 form, formulation, labeling, pharmacy documentation, and current FDA context all matter.
What Licensed Clinics Should Know About Methylcobalamin
Methylcobalamin is one of several forms, or vitamers, of vitamin B12.
FDA’s 2021 Pharmacy Compounding Advisory Committee materials distinguished methylcobalamin from cyanocobalamin and hydroxocobalamin. Those materials stated that methylcobalamin was not a component of FDA-approved products, while cyanocobalamin and hydroxocobalamin were components of approved products.
For clinic teams, the specific B12 form, formulation, labeling, dispensing entity, and supporting documentation should therefore be reviewed rather than relying on the general term “vitamin B12.”

Current FDA and 503A Context
FDA currently lists methylcobalamin in Category 1 — Bulk Drug Substances Under Evaluation for section 503A.
FDA defines Category 1 as substances that may be eligible for inclusion on the 503A Bulks List, were nominated with sufficient supporting information for FDA to evaluate them, and remain under evaluation.
Category 1 status is not FDA approval and does not mean methylcobalamin has been finally added to the 503A Bulks List.
FDA presented methylcobalamin to the Pharmacy Compounding Advisory Committee in 2021 and proposed that it not be included on the list. The committee voted 9–5 in favor of recommending inclusion.
That recommendation was advisory. FDA retains regulatory decision-making authority, and its May 14, 2026 materials continue to list methylcobalamin in Category 1 as a substance under evaluation
