In order for vitamins to be utilized by the body, they must first be converted into their active coenzyme forms. This coenzymated sublingual b-12 goes directly into your bloodstream in its active form, ready to go to work immediately. This avoids the loss that may occur not only during digestion, but during the liver's conversion process as well. Dibencozide is a primary active coenzyme form of Vitamin B-12. It is required for processing branch chain amino acids through the Krebs' cycle, for sustained energy production. Supplementation with dibencozide may reduce fatigue during prolonged exertion. Suitable for vegetarians and hypoallergenic.
