Coenzyme Q10 is used for energy production by every cell in your body, and also helps protect against cellular damage from free radicals. CoQ10 is especially important if you’re taking a statin drug as statins deplete your body of CoQ10, thereby speeding up progression of heart disease
 

Ubiquinol is the reduced form of CoQ10 – the effective form your body naturally uses to transfer free electrons – and research shows that this reduced form is superior for your health in a number of ways, primarily due to its superior bioavailability if you’re over 25

CoQ10 has been available for many decades, but the reduced version, ubiquinol, has only been commercially available for about six years. Prior to that it could only be made for research studies. There are well over 100 studies supporting its use and demonstrating its many health benefits, including its beneficial effect on statin-induced myalgia and other diseases rooted in mitochondrial dysfunction

Studies have demonstrated that ubiquinol has a positive effect on: inflammatory processes, septic shock (which is also associated with mitochondrial dysfunction), cardiac arrest and stroke recovery, and periodontal disease (including gingivitis and dry mouth)
