Encourages Red Blood Cell Function, Energy Metabolism, and Neurological Health.† Hydroxycobalamin is a precursor form of vitamin B12 converted in the body to both methylcobalamin and adenosylcobalamin. It is similar to cyanocobalamin without the cyanide component. 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. Optimal levels also upholds the healthy synthesis of neuronal myelin. It is a unique liquid blend of adenosylcobalamin and hydroxycobalamin that offers unmethylated B12 to promote nerve and mitochondrial health.
