Coenzyme Q-10

This treatment modality is used in place of conventional therapies to treat cancer. Seek advice from a qualified physician before replacing standard cancer therapy with coenzyme Q10 therapy.

What does therapy with coenzyme Q10 involve?

Coenzyme Q10 is a naturally occurring enzyme found in the body. It is a catalyst that promotes chemical reactions in the body without being used up or altered by the reaction. Coenzyme Q10 is available in tablets, capsules or oil-based gelcaps. 

How is coenzyme Q10 thought to treat cancer?

The major functions of coenzyme Q10 are as an antioxidant to protect cells from damage by oxygen and a stimulator of both cellular respiration and immune functioning. It is believed by proponents that cancer patients lack coenzyme Q10 in their blood. Coenzyme Q10 is thought to inhibit oxidation, stimulate the immune system and induce tumor remission.

What has been proven about the benefit of coenzyme Q10?

Deficiencies in coenzyme Q10 have been documented in cancer patients. Coenzyme Q10 deficiencies have also been associated with heart damage from Adriamycin chemotherapy treatment for cancer. Two different studies suggest that coenzyme Q10 provides protection against Adriamycin and lovastatin cardiotoxicity. The University of Texas M.D. Anderson Cancer Center conducted an extensive human studies literature review of coenzyme Q10 and found twenty-five studies applicable to cancer. After review of the available studies, M.D. Anderson Cancer Center reports that coenzyme Q10 may provide beneficial results as an adjunct cancer therapy through anti-oxidant and immune system enhancing properties.

What is the potential risk or harm of coenzyme Q10 therapy?

Side effects have rarely been reported, but headache, heartburn, fatigue, diarrhea, skin reactions and increased voluntary movement may occur.

How much does coenzyme Q10 cost?

Two hundred capsules of coenzyme Q10 cost approximately $100. They can be purchased at a variety of pharmacies and natural food stores.
