Research Data

What Is Vitamin B12?

Injectable methylcobalamin (vitamin B12) bypasses gastrointestinal absorption limitations, achieving near-complete bioavailability. B12 serves as a cofactor for methionine synthase (methyl group transfer, homocysteine metabolism) and methylmalonyl-CoA mutase (odd-chain fatty acid metabolism). Deficiency research and repletion studies demonstrate effects on neurological function, red blood cell production, and DNA synthesis.

Research Context

  • Methylcobalamin cofactor function in methionine synthase and methylmalonyl-CoA mutase
  • Homocysteine remethylation and cardiovascular risk factor modulation
  • Neurological function: myelin sheath synthesis and maintenance
  • Injectable vs oral B12 bioavailability and tissue uptake kinetics
  • Energy metabolism support in B12-deficient research models
