Adenosylcobalamin and hydroxycobalamin  B12  in liquid form—to support neurological and mitochondrial function.* Hydroxycobalamin serves as a precursor to both methylcobalamin and adenosylcobalamin, offering a cyanide-free alternative to cyanocobalamin. Adenosylcobalamin, the predominant mitochondrial form of B12, plays a critical role in cellular energy metabolism, particularly as a cofactor for methylmalonyl-CoA mutase in the conversion of propionate to succinyl-CoA. This process is essential for maintaining healthy myelin synthesis and optimal nervous system function.* The liquid format ensures enhanced bioavailability, easy administration, and is formulated with hypoallergenic, vegan-friendly ingredients.
