Coenzyme Q*0 (CoQ*0) is a substance that helps convert food into energy. CoQ*0 is found in almost every cell in the body, and it is a powerful antioxidant. It has shown many benefits for cardiovascular health and supplementing with it may improve blood sugar and help manage high blood pressure in people with diabetes. Primary dietary sources of CoQ*0 include oily fish (such as salmon and tuna), organ meats (such as liver), and whole grains. People lacking these foods in their diet, or taking strong medications, may be low in this essential enzyme. Supplement with CoQ*0 to support healthy cholesterol, maintain a healthy immune system, for improved energy production and antioxidant support.
