Coenzyme Q10 (CoQ10) is part of an enzyme complex that affects certain chemical reactions in the body. It occurs naturally in the body and can also be found in a number of foods, such as mackerel, salmon, sardines, beef, soybeans, peanuts, and spinach.
CoQ10 as a dietary supplement may promote health and fight some diseases, but more research is needed to find out the role of these supplements. Some small studies have suggested that CoQ10 may help treat cancer or reduce chemotherapy-related heart damage, but these results need to be confirmed by larger randomized clinical trials. It is uncertain whether CoQ10 reduces the effectiveness of chemotherapy, but most oncologists would recommend avoiding CoQ10 during chemotherapy.
Scientists believe CoQ10 is an antioxidant (a compound that blocks activated oxygen molecules, known as free radicals, that can damage cells), and that it may also have an effect on the immune system. Some studies have suggested that deficiencies of CoQ10 may contribute to certain diseases such as cancer.
CoQ10 is sometimes promoted as a treatment for cancer (most commonly breast cancer), often in combination with other vitamins. Supporters also claim CoQ10 supplements may protect the heart from the damaging effects of certain chemotherapy drugs, such as doxorubicin (Adriamycin).
CoQ10 supplements have also been promoted for heart disease, stroke, gum disease, and immune deficiencies. Some claim that CoQ10 can reduce pain and weight loss in people with cancer.
Many of these claims are currently being studied.
