Coenzyme Q10 (CoQ10) is an antioxidant that cells use to make the energy they need to grow and stay healthy. It’s in many living things and is sold as a dietary supplement. CoQ10 may help with some heart conditions but its effects on other conditions are generally inconclusive. If you take warfarin (a blood thinner), be aware that CoQ10 supplements may make the drug less effective.
