Our bodies rely on cellular energy for our heart and other organs to function effectively. CoQ10 is critical in the production of cellular energy and is produced naturally in our bodies. For CoQ10 to be effective in this process it must convert to its active form, Ubiquinol Ubiquinol is associated with over 90% of our cellular energy production. As we age, our bodies produce less CoQ10, which can result in lower Ubiquinol levels. By taking a Ubiquinol supplement, you can bypass the conversion process and replenish Ubiquinol levels. Look for the Kaneka Quality seal on your favorite brand of Ubiquinol.
