Coenzyme Q10 May Slow Parkinson's
High Doses of Popular Supplement Delays Deterioration
"While tremendously encouraging, ours is only a preliminary finding and still needs to be proved in a larger study," says Shults, who presented his study at the annual meeting of the American Neurological Association. "The next step is to do that, and we're working on a proposal to study the effects of coenzyme Q10 at even higher doses."
One concern: coenzyme Q10 is chemically similar to vitamin K, which is essential for blood clotting. "So it can negate the effectiveness of 'blood-thinning' drugs like Coumadin," says Lieberman. "While there's a study using 3000 mg of coenzyme Q10 to see its effect on ALS (amyotrophic lateral sclerosis, or "Lou Gehrig's disease"), most of the studies testing coenzyme Q10 on heart disease and other conditions involve smaller doses of around 300 mg." -->
