NOW Foods Vitamin B-12 Complex Liquid delivers a synergistic combination of vitamin B-12 (as cyanocobalamin), folate, and B-6 in a convenient liquid format for fast, flexible dosing. The liquid form allows for easy sublingual absorption — holding under the tongue for 30 seconds dramatically increases bioavailability compared to swallowing B-12 in tablet or capsule form, particularly important for those with low intrinsic factor production (common in older adults and those on acid-blocking medications). B-12 is essential for neurological function, red blood cell formation, and DNA synthesis, while folate and B-6 work synergistically with B-12 in the methylation cycle to reduce homocysteine — a cardiovascular and neurological risk factor. NOW Foods' liquid formula is free from artificial colors and flavors, pleasant-tasting, and ideal for children, seniors, or anyone who prefers liquids over pills.
