Not enough research for coenzyme Q10


coenzyme q10ROCHESTER, Minn., Nov. 3 (UPI) -- Scientific evidence doesn't support most of the health claims concerning coenzyme Q10, but some studies do have merit, says a U.S. newsletter.

It's not known if low coenzyme Q10 levels cause disease or if taking supplements can prevent or treat disease, according to the Mayo Clinic Health Letter.

Of the many coenzyme Q10 studies, most have been small. Many have not been "controlled," where some participants take a placebo, but some coenzyme Q10 studies appear to have scientific merit, the newsletter says.

There has been some evidence of benefit for people with Parkinson's disease, migraine and high blood pressure, but more studies are needed, the newsletter says.

"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," says the newsletter.

"The role for this supplement in any therapy is supportive at best. It's not a substitute for proper medical care."
