Coenzyme Q10 occurs in small amounts in the diet, such as meat and fish. The body can produce Q10 itself, but athletes and the elderly can sometimes some extra use. Especially endurance athletes can, if desired, use additional Q10.
In the body, coenzyme Q10 especially for as ubiquinol, the active form of Q10. Ubiquinol is better absorbed by the body than conventional ubiquinone because it is readily available. Until recently, this variant of Q10, however, not stable for use in a nutritional supplement, since the compound is very sensitive to light and air. Moreover crystallizes coenzyme Q10 in oil form and thus impedes the absorption of Q10.
A very recent development is the combination of the patented stable form of ubiquinol with d-limonene. D-limonene is a volatile oil from citrus fruits.
This prevents the formation of crystals. By the addition of alpha-lipoic acid are ubiquinol and d-limonene effectively protected from oxidation. ReduQuinol contains the patented form of ubiquinol and d-limonene. ReduQuinol with reduced CoQ10 (ubiquinol) is readily available and stomach friendly.
