The APortha ® Q10Vital ® Coenzyme Q10 oral spray offers the following benefits: 50 mg of water-soluble, highly bioavailable coenzyme Q10Vital ® Q10 per recommended daily dose (5 sprays, easy application) individual optimal dose in 10 mg increments The dietary supplement offers very effective absorption directly through the oral mucosa, optimized with heart-healthy vitamin B1 (thiamine), which contributes to the normal functioning of the heart. Product features: Q10Vital ® is a unique, patented, water-soluble form of Coenzyme Q10 (ubiquinone) with a bioavailability up to 4 times higher than conventional, crystalline Coenzyme Q10. When administered from the bottle as an oral spray, Q10Vital ® Coenzyme Q10 is absorbed through the oral mucosa, sent directly to the heart via the superior vena cava and distributed throughout the body. This circumstance increases bioavailability. Crystalline coenzyme Q10, which is absorbed through the gastrointestinal tract, has a low bioavailability of only about 6%. With 50 mg of Q10Vital ® per day as an oral spray, you can easily and safely replace 200 mg of crystalline coenzyme Q10 from capsules or tablets. Ubiquinol or ubiquinone? Because our body needs both forms of coenzyme Q10 and converts them from one form to the other as needed, the form of coenzyme Q10 (ubiquinol or ubiquinone) in which we absorb it is insignificant.
