Coenzyme Q10 (CoQ10) is an essential nutrient produced in your body that assists with producing energy for cells – particularly those found in your heart and brain. CoQ10 also acts as an antioxidant; low levels have been linked to conditions like cancer and diabetes, as well as helping reduce oxidative damage which leads to muscle fatigue and skin diseases. CoQ10 dietary supplements appear safe when taken orally.

CoQ10 has been shown to decrease LDL cholesterol oxidizability and decrease oxidized blood glucose (Molyneux et al. 2000). Furthermore, its use has proven successful at reducing atherosclerotic lesions as well as improving vascular endothelial function among those suffering from Type II diabetes (Watts et al. 2002 and Belardinelli et al. 2006).

Studies conducted in vitro indicate that ubiquinol, the reduced form of CoQ10, may be more biologically active than its parent molecule. Ubiquinol comprises 93-5 percent of total plasma CoQ10 levels for healthy individuals worldwide and researchers worldwide are working to further research on ubiquinol.

Supplemental CoQ10 is a natural substance found in oily fish, organ meats (such as liver), whole grains and as dietary supplements produced via yeast fermentation process. While not regulated by the FDA and ingredients may vary between batches; some studies have reported that supplementing CoQ10 with increased energy may enhance endurance exercise performance while other results were inconsistent.
