Coenzyme Q10 (CoQ10) is a naturally occurring antioxidant found within the human body and is a key component of cellular respiration, a process in which the body makes energy. CoQ10 can also be obtained via supplementation. Touted by the University of Maryland Medical Center as an energy-booster, CoQ10 is clinically studied for its health benefits.
Cardioprotective Benefits
CoQ10 offers cardioprotective health benefits, guarding against heart disease, heart failure and high blood pressure. The Memorial Sloan-Kettering Cancer Center reports that CoQ10's antioxidant properties have a demonstrated ability to carry out essential physiological functions of the myocardium (heart muscle) during episodes of ischemia (insufficient blood flow). Additionally, a study published in a 2007 edition of the "European Heart Journal" determined that when supplemented with 300 mg of CoQ10 daily for one month, patients displayed improved endothelial function, which allowed for better blood flow.
Anticancer Benefits
CoQ10 is additionally recognized for its anticancer properties. The American Cancer Society relays that some studies have shown a correlation between low plasma levels of CoQ10 and cancer. While correlation does not equal causation, the University of Maryland Medical Center reports that studies have shown CoQ10 (in addition to other traditional treatments and dietary supplementation) reduces tumor size and pain in women with breast cancer. An additional benefit of CoQ10 may be its ability to protect against toxicity associated with various cancer treatments. A review published in a 2004 edition of the "Journal of Clinical Oncology" reports that CoQ10 may help to guard against cardiotoxicity or liver toxicity during cancer treatment.
Additional Benefits
Besides its cardioprotective and anticancer benefits, CoQ10 may provide additional benefits to health conditions ranging from diabetes and high cholesterol to periodontal (gum) disease and fatigue. The University of Maryland Medical Center reports that research has shown that people with periodontal disease often possess lower levels of CoQ10 in their gums. Additionally, a clinical study published in a 2008 edition of "Nutrition" discovered that CoQ10 supplementation improves physical-performance-inducing fatigue and the overall sensation of fatigue.
