Research brief · Metabolic
Vitamin B12
Cobalamin cofactor used in methylation and lipotropic research.
Class
Cobalamin cofactor
Half-life
~6 days (systemic)
Studied in
One-carbon metabolism, methylation and lipotropic research models.
What it is
Vitamin B12 (cobalamin) is an essential cofactor used in laboratory research as a reference compound for one-carbon and propionate metabolism, and as a co-component of lipotropic research blends.
Mechanism studied
Cofactor for methionine synthase and methylmalonyl-CoA mutase in one-carbon and propionate metabolism.
Research notes
- Standard component of MIC / Lipo-C lipotropic research blends.
- Methylcobalamin and cyanocobalamin forms differ in cofactor handoff kinetics.
Before sourcing any material
- Confirm a lot-matched third-party certificate of analysis (HPLC purity and mass-spectrometry identity).
- Check the stated peptide content per vial, not just the gross vial mass.
- Plan reconstitution volumes first so the vial size matches your protocol.
- Verify what is lawful in your jurisdiction — these are in-vitro research reagents, not medicines.
