Coenzyme Q10 is a molecule that plays an important part in providing energy to the body's cells, according to the University of Maryland Medical Center. It is also an antioxidant that cleans up damaging chemicals in the body's cells known as free radicals. Coenzyme Q10 is used for a wide variety of diseases, but many of its uses are unproven, according to MedlinePlus. Consult your doctor before taking coenzyme Q10.
Best Evidence
Coenzyme Q10 deficiency is a rare disorder that causes weakness, tiredness and seizures and is probably effectively treated with coenzyme Q10 supplements, according to MedlinePlus. Coenzyme Q10 may also be effective against certain mitochondrial disorders that affect energy production in the cells. But if it works, it works slowly, according to MedlinePlus. It may take six months or more for symptoms to improve. Consult a doctor to be sure this is the best option for you.
Heart and Related Conditions
Some evidence suggests that coenzyme Q10 might be helpful for congestive heart failure, guarding against additional heart problems after a heart attack, preventing blood vessel damage caused by bypass surgery and lowering high blood pressure, according to MedlinePlus. However, the research on these issues so far is not conclusive. Talk to your doctor before starting treatment with coenzyme Q10 for any of these issues, as they are serious conditions and the supplement could interfere with proven treatments. For example, coenzyme Q10 might increase the effectiveness of your blood pressure medication, lowering blood pressure too much, which would require an adjustment in your treatment plan, according to MedlinePlus.
Other Conditions
An altered form of coenzyme Q10, known as ubiquinol, is being studied as a possible treatment for Huntington's disease, according to MedlinePlus. However, early studies show that taking coenzyme Q10 in doses of 600 mg a day is not effective. Some research indicates that coenzyme Q10 may help prevent some migraine headaches, though it does not affect them once they have started. It can take up to three months for the supplement to work, according to MedlinePlus. Also, some evidence suggests coenzyme Q10 may be helpful for early Parkinson's disease, HIV/AIDS patients and people with muscular dystrophy. But these uses are not proven, so consult a doctor before trying the supplement.
