B12, Activated by Daily Manufacturing (180 caps)

What the brand says

Vitamin B-12 in our food supply is estimated to be 78% less than in the 1960s. Diet alone is hard pressed to provide the necessary levels of this important nutrient. In addition, stress and reduced hydrochloric acid (HCl) and intrinsic factor production in the stomach impair absorption. The most commonly used forms of B-12 require activation in the body, making uptake quite low - rarely more than 50%. Activated B-12 contains equal amounts of 5-deoxyadenosyl cobalamin and methylcobalamin. These are the active forms of vitamin B-12. For normal absorption, B-12 requires intrinsic factor; but even without intrinsic factor, 1-2% of B-12 can be absorbed. Therefore, since there are 500 mcg per capsule, considerably more than the RDA of 2 mcg should be absorbed by anyone taking it.
