What is the best brand of CoQ-10?

While there are many brands of Coenzyme Q10 supplements, research reported by WebMD and the National Institute for Health shows that CoQ10 that contains active ubiquinol is more effective than supplements that contain ubiquinone. More effective ingredients mean smaller doses and limited side effects, as stated by the Mayo Clinic.

Coenzyme Q10 is a fat-soluble nutrient that naturally occurs in the body in two forms: ubiquinol and ubiquinone, according to WebMD. Research showing that ubiquinol has a higher bioavailability than ubiquinone was confirmed by researchers at The Ohio State University's Human Nutrition Program in 2014, as reported by the National Institute of Health.
