Coenzyme Q10 (CoQ10) plays a vital role in cellular energy production, generating energy in the cell?s powerhouses called mitochondria. The highest concentrations of cell mitochondria are found in the hardest working cells in the body, such as the heart, making CoQ10 important to help support heart function. Certain statin drugs can reduce CoQ10 levels in the body. Nature Made CoQ10 can help replenish this important nutrient.
