CoQ10 is a coenzyme that helps enzymes function in the body. In addition to its antioxidant properties, CoQ10 may be used as a complementary treatment for chronic health conditions such as heart disease and cancer. While CoQ10 can also be found in foods, you should not take CoQ10 supplements without first talking to your doctor.
What is CoQ10?
CoQ10 is the short name for coenzyme Q10, a substance your body uses to make the energy needed for your cells to function. CoQ10 is abundant in your organ tissues, such as the liver, kidneys and heart. The aging process can reduce your body's natural CoQ10 levels, as can certain prescription medications such as statins or antidepressants. Taking CoQ10 supplements may not only help prevent a potential coenzyme deficit but may also play a role in the treatment of other medical conditions such as gum disease, heart disease and cancer.
CoQ10 and Cancer
CoQ10 has antioxidant properties. Antioxidants are substances that fight free radicals in the body, which can speed the aging process and lead to a number of chronic health conditions. CoQ10 may not only boost the immune system, according to the University of Maryland Medical Center, UMMC, but can also destroy some of these unhealthy substances that may increase your cancer risks. Supplemental CoQ10 may prevent cancer cells from forming and growing in your body, according to the National Cancer Institute. While most of the studies to date have involved animals only, the National Cancer Institute reports the supplement does show promise in both the treatment and prevention of cancerous tumors.
Clinical Evidence
Most of the research involving CoQ10's effects on tumors relates to breast cancer. CoQ10 supplementation has contributed to tumor reduction and cancer remission in more than one trial, according to the National Cancer Institute. CoQ10 was not the only supplement used, however, and other standard treatments may have also played a role in tumor size. UMMC reports that CoQ10, used along with other antioxidants such as vitamins C and E, did seem to help shrink breast cancer tumors. Whether CoQ10 itself shrunk the tumors, or it was a combination of many supplements and treatments, is not entirely evident. MayoClinic.com grades the evidence for CoQ10 use a "C" when it comes to both breast and prostate cancer treatment because the scientific evidence remains unclear.
Guidelines
CoQ10 is one of many antioxidants that can help people with cancer, although it may or may not contribute to tumor reduction. CoQ10 may, however, prevent some chemotherapy drugs from negatively affecting your heart. It should not be taken without the guidance of your doctor, and CoQ10 should not be used as a substitute for your usual medications. While most side effects are not serious, CoQ10 can cause digestive upsets, a rash or irritability. It may also interfere with the effect of certain blood-thinning medications.
