Ubiquinol is the active, antioxidant form of CoQ10 that’s ready for immediate use by the body. Conventional CoQ10 supplements, however, use the inactive form of Coenzyme Q10 called Ubiquinone.
Ubiquinol supplements are typically stocked on the same shelf as conventional CoQ10 supplements in pharmacies, vitamin shops, and in the supplement aisles or health sections of most grocery stores. When shopping, you should be aware that many Ubiquinol supplements are often labeled as “CoQ10 Ubiquinol,” which can cause some confusion. To avoid any guesswork, check the supplement facts label on the bottle for “Ubiquinol (Kaneka QH®).” Authentic Ubiquinol products include the Kaneka QH logo, so you can be certain you are buying the active, antioxidant form of CoQ10.
