What is coq10?

CoQ10 is used by mitochondria to make energy and acts as an antioxidant. The body makes less with age, and statins lower it further. Studies suggest benefits for some people with heart conditions and for statin-related muscle aches, though results vary.

Forms. Ubiquinone (standard) and ubiquinol (active form). Softgels with oil absorb best.
