B12-ND 2 fl oz

Premier Research Labs’ B12-ND contains fully active co-enzymes of vitamin B12 that are rich in the desirable “blood circulating forms” of vitamin B-12 , namely, methylcobalamin, adenosylcobalamin and hydroxycobalamin. When vitamin B12 is provided as methylcobalamin, it is already in the biologically active form and is able to yield optimal bioavailability and tissue retention. B12-ND is a probiotic-fermented, vitamin B12 formula that uses a unique probiotic culture which allows rapid oral delivery with superior bioenergetic properties. Refrigerate after opening.
