Not all B12 Vitamins are created equal! When looking to supplement B12 into your daily diet, make sure that you are getting the best, most absorb-able form of this essential vitamin.* Many B12 products, as well as multivitamins, use synthetic Cyanocobalamin. This non-active form of B12 needs to be converted in the body to an active form, versus the readily active version Methylcobalamin. That is why we used this preferred form in our Mega B-12, which delivers a full 1,500 mcg per serving.* Because B-Vitamins are water-soluble nutrients that are not readily stored in the body and can be easily eliminated, we utilize our Liquid Soft-Gel delivery along with our BioPerine Complex, to ensure that this essential vitamin is delivered fast into your system.*
