CoQ10 MAY PREVENT PARKINSON’S
The popular dietary supplement coenzyme Q10 (CoQ10 or ubiquinone) appears to
slow the progression of Parkinson’s disease, according to the results of a study
presented at the American Neurological Association’s 127th annual meeting in New
York City. The study also appears in the Archives of Neurology.
Clifford Shults, MD randomly assigned 80 patients to regimens of CoQ10 at
dosages of 300, 600, or 1200 mg/day, or to a placebo group. Patients were
assessed one month after beginning the study and then every four months during
the sixteen-month study. Neither the patients nor the study investigators knew
which treatment a patient was receiving until after the study was completed.
By the eighth month, patients taking the highest (1200 mg) dose of CoQ10 were
scoring significantly better on the Unified Parkinson Disease Rating Scale than
patients in the other groups.
By the end of the trial, patients in the high-dose group were scoring 44% better
than the placebo group on the test battery.
