What is Vitamin B12 Methylcobalamin 1mg/mL?

Vitamin B12 Methylcobalamin 1mg/mL (Injectable bioactive cobalamin — research grade) is methylcobalamin — the active, methyl-donor form of B12 — in aqueous injectable solution. Unlike cyanocobalamin, methylcobalamin is the biologically active coenzyme form requiring no conversion. Essential coenzyme for methionine synthase (homocysteine → methionine methylation cycle) and methylmalonyl-CoA mutase (odd-chain fatty acid metabolism). Critical for myelin synthesis, neural function, DNA methylation, and red blood cell production.

Research Applications

Methylation Cycle Research

Methionine synthase coenzyme — homocysteine to methionine conversion and SAM cycle

Neurological & Myelin Research

B12 in Schwann cell myelination — peripheral neuropathy, nerve regeneration, and neurological function

DNA Methylation

SAM-dependent methylation — epigenetic regulation, gene expression, and cell differentiation

B12 Deficiency Models

Injectable B12 for rapid repletion in pernicious anaemia and malabsorption research models

Methylcobalamin vs Cyanocobalamin

Active methylcobalamin direct bioavailability vs cyanocobalamin hepatic conversion requirement
