Vitamin B-12: 2,000mcg/ml 5ML

Vitamin B-12 (Methylcobalamin) - 2,000mcg/mL, 5mL Vial

Vitamin B-12 (cobalamin) is an essential water-soluble vitamin that serves as a cofactor for two critical enzymes: methionine synthase and L-methylmalonyl-CoA mutase. These enzymes are required for DNA synthesis, red blood cell formation, myelin maintenance, and the conversion of homocysteine to methionine. This formulation provides methylcobalamin, the bioactive coenzyme form that requires no hepatic conversion.

Why Methylcobalamin

Methylcobalamin is the neurologically active form of B-12 that participates directly in the remethylation of homocysteine and the maintenance of myelin sheaths surrounding nerve fibers. Unlike cyanocobalamin (the synthetic form found in most supplements), methylcobalamin does not require enzymatic conversion and is immediately available for metabolic use. Research suggests methylcobalamin may have superior retention and neurological bioavailability.

Key Research Applications

Published studies have investigated methylcobalamin in the context of homocysteine metabolism, methylation cycle function, red blood cell production, neurological function and nerve conduction velocity, energy metabolism, and cognitive performance in B-12 deficient models.
