DescriptionSome people vape to get high, others vape to get healthy. You'll be firmly in the latter with VitaminVape. Each of these Vitamin B12 vaporizers contains 28 servings of 500 mcg, or 14,000 mcg, which is about 14 times the amount found in a typical B12 shot. And with three vaporizers, it's more like 42 times! Considering adults are supposed to get about 2.4 mcg of B12 each day, a single serving is more than enough to meet your daily quota.
