Coenzyme Q10 is a ubiquitous molecule that can be seen everywhere in the human body. This is good news! Because it can be used as a powerful antioxidant. By definition, almost any molecule in your body that releases and receives electrons has a similar antioxidant effect. Your excess coenzyme Q10 (those molecules that do not participate in energy production) can shuttle through various membranes in your body to provide antioxidant protection.
