Adenosyl/Hydroxy B12

Adenosyl/Hydroxy B₁₂ offers a unique blend of vitamin B₁₂ , as adenosylcobalamin and hydroxycobalamin. Hydroxycobalamin is a precursor form of vitamin B₁₂ converted in the body's to both methylcobalamin and adenosylcobalamin. It is similar to cyanocobalamin without the cyanide moiety. Adenosylcobalamin is an activated form similar to methylcobalamin. While methylcobalamin is found in the cytosol of cells and predominates in blood and other fluids, adenosylcobalamin is the major form of vitamin B₁₂ stored in the mitochondria of cellular tissues. It is a key cofactor in carbohydrate metabolism for the enzyme methylmalonyl-CoA mutase used to produce succinyl-CoA.¹ Optimal levels also support healthy synthesis of neuronal myelin.^2‡
