Increase of bioavailability of coenzyme Q(10) and vitamin E

Commercial coenzyme Q(10) (CoQ(10)) and alpha-tocopherol (vitamin E) formulations often show poor intestinal absorption. Delivery of CoQ(10) and vitamin E was enhanced when used with a new formulation, NanoSolve (Lipoid GmbH, Ludwigshafen, Germany), as shown by an open, comparative monocenter, crossover study of 24 volunteers. Plasma CoQ(10) and vitamin E were determined from predose until +14 hours. To compare bioavailability, corrected maximum concentration, time to reach maximum concentration, and area under the curve from 0 to 14 hours were assessed. The NanoSolve test formulation contained 100 mg of CoQ(10) and 120 mg of vitamin E. The pure substances in hard gelatin capsules served as the reference. Although identical amounts of CoQ(10) and vitamin E were administered, absolutely higher serum concentrations of the active ingredients were achieved by the NanoSolve formulation than by the pure materials in gelatin capsules. The bioavailability of CoQ(10) increased fivefold after administration of the NanoSolve formulation, and the bioavailability of vitamin E was enhanced 10-fold both compared to the pure substances.
