One of the most important Co-Enzymes is Co-Enzyme-Q10. This substance plays a critical role in the creation of cellular energy. It is critical to the cellular ATP (energy) production cycle. Most Co-Q-10 supplements are in the form of Ubiquinone. Ubiquinone has to be converted into Ubiquinol by the body. However, starting at age 30, the body has a harder time converting Ubiquinone into Ubiquinol and this process gets less efficient as we age. Until 10 years ago all Co-Q-10 supplements were made with Ubiquinone, as Ubiquinol was not stable outside the body. This problem was overcome by a company called Kaneka, who developed a unique, stabilised, patented Ubiquinol supplement, called KanekaQH Ubiquinol. KanekaQH Ubiquinol is the only stable Ubiquinol supplement on the market. Natures Aid Ubiquinol is made using the patented, stablised KanekaQH Ubiquinol and provides a full 50mg Ubiquinol per capsule.
