Coenzyme Q10 is a naturally occurring substance that your body makes in small doses. As you grow older, your natural production of Co-Q10 decreases, which is why many people choose to take supplements or find ways to get more Co-Q10 into their diet. Coenzyme Q10 works as an antioxidant, helping to protect your cells from oxidative stress, which happens as you age but can be made worse by pollutants such as cigarette smoke. Co-Q10 may help to lower blood pressure slightly, and may help to improve some heart conditions.
