What is Chewable Fully Active B12?
Chewable Fully Active B12 is a fast acting and pleasant tasting vitamin B12, provided as Methylcobalamin, its most biochemically active form. Vitamin B12 is essential for healthy mood and memory management and for fundamental life processes such as healthy gene regulation (epigenetics), nerve cell communication, and the recycling of homocysteine, a potentially toxic metabolite, from pregnancy through old age.

How does it work?
Vitamin B12 is the most chemically complex of all the vitamins. The most basic B12 unit is cobalamin, a large molecule with an intricate cage-like structure that encloses a single cobalt atom. The cobalt atom is highly reactive on its own, but the cobalamin cage channels its reactivity to serve specific biochemical functions. For use as an enzyme cofactor the B12 usually has another chemical group attached, which most often is a methyl group. Vitamin B12 is a necessary cofactor for two human enzymes, but both are important for basic life processes. Impairment of their functioning due to mutations or insufficiency of B12 can pose serious threats to health.
