— Increasingly Popular Supplement, But Health Professionals and Consumers Cautioned To Check Brands —
WHITE PLAINS, NY — January 13, 2004 — (Updated January 30) — today announced that among the coenzyme Q10 (CoQ10) supplements it recently tested there was no detectable CoQ10 in one product. Such a variation is of medical concern since CoQ10 is used in treating tightly controlled conditions such as congestive heart failure, Parkinson's disease, hypertension, and AIDS. CoQ10 acts as an anti-oxidant and is also involved in energy production.

Total U.S. sales exceed $200 million, making CoQ10 one of the top selling supplements according to Nutrition Business Journal. Over the past year, sales of CoQ10 products increased 22% in the U.S. mainstream channel and 30% in the health food store channel according to research firms AC Nielsen and SPINS.*

"When a patient can go from full dose to zero dose just by switching brands, there is potential for a real problem in managing a disease," said Tod Cooperman, M.D., President of "Patients and doctors may never suspect a change in supplement brand to be the reason for a change in a patient's condition." Dr. Cooperman urged people to use CoQ10 products that have been independently tested. first warned of potential problems with CoQ10 in November 2000 when it found a product that contained only 17% of its claimed amount.
