Bests & Worsts Reviews from Amazon

Liquid dosed via a dropper is a handy way to supplement with vitamin B-12, but it actually isn't necessary to take 5000 mcg at a time. The body can't absorb a relatively huge amount like that all at once, and it is not necessary for any health reason either. Therefore, when I take this supplement, I suck only about 1/4 inch of B-12 liquid into the very tip of the dropper, and I administer it under my tongue for immediate absorption into the bloodstream. The blood vessels under the tongue are among the closest to the surface of the skin in the body, and the mucous membranes are very thin. This supplement has a pleasant taste and it's easy to administer. I will definitely purchase it again.
