The National Cancer Institute stated the body can use CoQ10 to protect cells from damage that might lead to cancer. Animal studies have shown it helps the immune system work better and helps the body resist infections and certain cancers, according to the institute, which also points out studies in breast cancer patients have resulted in patients improving with CoQ10 treatment.
Researchers at the University of Western Australia in Perth found that CoQ10 improved blood pressure when used by people with type 2 diabetes. The study, published in the November 2002 issue of the "European Journal of Clinical Nutrition" tested 74 subjects and showed it also helped control blood glucose levels.
Evidence suggests that there is often a CoQ10 deficiency in heart failures and CoQ10 plasma concentrations have also been used as a predictor of mortality in heart failure. Oxidation of the circulating LDL is thought to play a key role in causing heart attacks and strokes and ubiquinol (a form of Coenzyme Q10) in human LDL provides protection against the oxidation process, resulting in a healthy heart for you.
