What Are the Benefits of Coenzyme Q 10?

Coenzyme Q10 is a powerful antioxidant that is found in the human body and necessary for cells to function properly. Also called ubiquinone, coenzyme Q10 helps guard the body from free radicals known to play havoc with the immune system, which in turn cause disease. Even though coenzyme Q10 occurs naturally in the body, as people age, the body produces less and less of this essential vitamin-like substance.


According to the Mayo Clinic, coenzyme Q10 has been used, recommended, and/or studied for numerous conditions, but still needs much research and is somewhat controversial as treatment for health disorders. Yet people have included taking coenzyme Q10 along with their multivitamin in hopes that the supplement will help their chronic conditions and make them feel more energetic.

Major Benefits

Coenzyme Q10 has had many claims in helping medical disorders such as fighting gum disease, chronic fatigue syndrome, HIV/AIDS, migraines, ringing in the ears, and others, however, the ones below have had studies conducted and are being researched further. The University of Texas at Austin has recognised coenzyme Q10 as a major supplement to help in cardiovascular diseases. Studies in Japan also report patients taking coenzyme Q10, under the direction of their physicians, have lowered blood pressure, strengthened the heart muscle and immune system. These Japanese studies also suggest that this supplement helps protect the stomach lining and duodenum, and may help heal ulcers. Research has revealed that supplementation with coenzyme Q10 has the ability to counter histamine, making this supplement helpful for people with allergies and asthma. According to the American Cancer Society, small studies have been conducted suggesting that coenzymeQ10 may help treat cancer or reduce chemotherapy related heart damage.


In order to reap the rewards of this powerful antioxidant, make sure to include fish in your diet (mackerel, salmon and sardines). It is also found in beef, peanuts and spinach. However, in order to get a therapeutic dose from your diet, one would have to consume more than 2.72 Kilogram of beef, 6.35 Kilogram of peanuts, and 2.72 Kilogram of sardines daily, according to Dr. Erika Schwartz MD (an internist in New York) as stated in the book Alternative Cures: The Most Effective Natural Home Remedies for 160 Health Problems by Bill Gottlieb, 2000. Dr. Schwartz suggests taking 30-milligram supplements twice a day along with a meal.

Side Effects

No serious side effects have been reported although mild ones can occur. Consult a physician if you experience nausea, vomiting, diarrhoea, loss of appetite, itching, rash, insomnia, headache, dizziness, fatigue or flu-like symptoms. Be cautious if you have low blood pressure or taking hypertension medication, as coenzyme Q10 may decrease blood pressure.


The U.S. Food and Drug Administration does not regulate supplements or herbs, therefore, there is no guarantee on the strength, purity or safety of these nutritional supplements. If you have a medical condition or taking prescription medications, it is best to check with a health care provider before taking coenzyme Q10.
