Longevity · 500mcg/mL, 2000mcg/mL · TBD

Vitamin B12 (Cyanocobalamin) is a cobalt-containing corrinoid compound involved in methylation pathways, red blood cell formation, and mitochondrial energy metabolism. It has been studied extensively in longevity and metabolic research for its relationship to homocysteine regulation, neurologic signaling, DNA synthesis, and cellular energy production across a wide range of physiologic models. Its cobalt-centered corrin ring structure distinguishes it from other water-soluble vitamins and is fundamental to its enzymatic cofactor activity. Sterile injectable solution. Sold at 500mcg/mL and 2000mcg/mL concentrations. For research use only.

Cyanocobalamin form. Methylcobalamin (MeCbl, CAS 13422-55-4, MW 1344.40) is the active coenzyme form. Vial size pending vendor confirmation.
