Ubiquinol supplements deliver a more bioavailable—or body ready—form of CoQ10 (Coenzyme Q10). CoQ10 is an important nutrient found throughout the body, but your body must break it down into a usable form. That usable form is ubiquinol, and more than 90% of the CoQ10 found in your body is stored in the form of ubiquinol, a “ready-to-go reserve” of CoQ10 power. For adults over the age of 50, supplementing with ubiquinol is a smart move, as the body’s ability to naturally produce CoQ10 declines with age. Swanson offers the lowest price on this advanced CoQ10 supplement.
