Coenzyme Q10: Should You Take This Supplement?

November 7, 2006

You may have heard claims that the supplement coenzyme Q10 can lower

blood pressure, boost the immune system and improve certain heart

diseases. There are also claims it can help fight cancer,

Parkinson's disease, wrinkles, diabetes, gum diseases and many other

problems.

It appears that taking a coenzyme Q10 supplement should be

beneficial. Coenzyme Q10 is a vitamin-like compound found in the

energy-producing center of each cell in the body. It plays a vital

role in producing energy in cells. It's also an antioxidant, a

natural compound thought to protect against disease. And,

concentrations of coenzyme Q10 decline with age and are low in

people with diseases such as heart disease, Parkinson's disease,

cancer and diabetes.

But according to the November issue of Mayo Clinic Health Letter,

scientific evidence doesn't support most of the health claims. So

far, it's not known if low coenzyme Q10 levels cause disease or if

taking supplements can prevent or treat disease. Of the many

coenzyme Q10 studies, most have been small. Many have not

been " controlled, " where some participants take a placebo.

However, some coenzyme Q10 studies appear to have scientific merit.

There has been some evidence of benefit for people with Parkinson's

disease, migraine and high blood pressure, but more studies are

needed. So far, there's not enough evidence to make medical

recommendations.

Talk with your doctor about the pros and cons before taking coenzyme

Q10 to help treat a disease. The role for this supplement in any

therapy is supportive at best. It's not a substitute for proper

medical care.
