COQ10 is a fat-soluble antioxidant that provides protection against development of breast cancer; researchers have found that women who have low levels of CoQ10 in their blood have a higher risk for developing breast cancer.
Levels of CoQ10 drop as we age and can be depleted by medications such as statin drugs. Low levels of coenzyme Q10 are associated with increased cancer incidence and poor recovery (Cooney, 2011). Coenzyme Q10 is critical to production of adenosine triphosphate (ATP) and energy production (Lance, 2012). CoQ10 levels can be increased with supplementation which is effective in treating oxidative stress in those who have low circulating levels in their blood.
CoQ10 supplementation also provides therapeutic actions for breast cancer treatment as it has been found to program cancer cells to self-destruct via apoptosis.
CoQ10 supplementation appears to enhance tamoxifen therapy by restoring mitochondrial function and reducing tumor necrosis factor. A supplement containing coenzyme Q10, riboflavin, and niacin was found to reduce markers of breast cancer cells in those also taking tamoxifen (Yuvaraj, 2008).
Only take the form of CoQ10 called ubiquinol. Avoid the ubiquinone form.
Recommendation: 100 mg ubiquinol per day.
