Methods and compositions that enhance bioavailability of coenzyme-Q10
View Patent ↗Bioavailability of Coenzyme-Q10 (“Co-Q10”), an oil-soluble substance, can be enhanced in a subject by modifying, e.g. nanonizing or charging, the form of Co-Q10. Co-Q10 bioavailability also can be enhanced by administering Co-Q10 to the subject as an oil (lipid)-based and water (hydro)-based mixed composition, along with other optional components, such as oils, resins and other carriers. Accordingly, the invention provides various Co-Q10 compositions, e.g. compositions comprised of (i) Co-Q10 dissolved in one or more Co-Q10-soluble oils and (ii) Co-Q10 in admixture with at least one water-dispersible agent. A Co-Q10 complex of the invention, therefore, yields an increased cell absorption rate, as well as an enhanced percentage of Co-Q10 peak absorption, compared to previously known compounds. Methods for making and using the aforementioned compositions also are provided.
1. A composition comprising
an effective amount of nanosized crystalline coenzyme-Q10;
at least one hydro-dispersible compound; and
a pharmaceutically acceptable carrier,
wherein the hydro-dispersible compound selected from the group consisting of lecithin, polysorbate-80.
2. The composition according to claim 1 , further comprising at least one lipid-based compound that dissolves the coenzyme-Q10 and enhances bioabsorption of the coenzyme-Q10.
3. The composition according to claim 2 , wherein said lipid-based compound is selected from the group consisting of a tocopherol, a vegetable oil and lecithin.
4. The composition according to claim 3 , wherein said tocopherol is selected from the group consisting of an alpha tocopherol, a beta tocopherol and a gamma tocopherol.
5. The composition according to claim 3 , wherein said vegetable oil is selected from the group consisting of palm, coconut, palm kernel, palm stearin, coffee, soya, soybean oil, safflower, canola, rapeseed, flax, cotton, cottonseed, wheat germ oil, maize germ oil, sunflower, lucerne oil, poppy oil, red kuri oil, sesame oil, rapeseed oil, evening primrose oil, millet oil, barley oil, quinoa oil, rye oil, candlenut oil passionflower oil, and rape seed oil.
6. The composition according to claim 1 , wherein said coenzyme-Q10 has a net ionic positive or negative charge.
7. A composition according to claim 1 , wherein said composition is a dietary, nutritional or pharmaceutical composition.
8. A composition according to claim 1 , wherein the nanosized crystalline coenzyme-Q10 is substantially purified.
9. A composition or formulation according to claim 1 , further comprising an ion exchange resin.
10. A composition or formulation according to claim 9 , wherein said coenzyme-Q10 is coated on said resin.
11. A method for treating a patient suffering from a condition associated with decreased Co-Q10 levels, comprising the steps of:
administering to said patient an effective amount of a composition or formulation according to claim 1 ; and
observing a reduction in severity or frequency of at least one symptom associated with said condition, wherein said condition is selected from the group consisting of an age-related degenerative disease, periodontal disease, a blood-circulation disease, impaired memory, fatigue, coronary disease, irregular heartbeat, high blood pressure, immune system impairment, and the aging process.
12. A composition for enhancing the bioavailability of coenzyme Q-10 comprising nanosized crystalline coenzyme Q-10, polysorbate 80, and a pharmaceutically acceptable carrier, wherein the composition enhances the bioavailability of coenzyme Q-10.
13. The composition for enhancing the bioavailability of coenzyme Q-10 of claim 12 , wherein the composition is combined with a tocopherol and a vegetable oil.
14. The composition for enhancing the bioavailability of coenzyme Q-10 of claim 13 , wherein the composition is combined with a resin.
15. The composition for enhancing the bioavailability of coenzyme Q-10 of claim 14 , wherein the resin is an ion-exchange resin.
16. The composition for enhancing the bioavailability of coenzyme Q-10 of claim 14 , wherein the resin is coated with nanosized, crystalline coenzyme-Q 10.
