WHITE PLAINS, NY — November 2, 2003 — today announced test results for supplements used in treating osteoarthritis that contain glucosamine, chondroitin, and/or MSM. These ingredients accounted for $790 million in product sales in 2002 according Nutrition Business Journal and are also popular supplements for pets. Several combination products were found to be low in chondroitin — a particularly expensive ingredient. Two products for use by people contained less than 20% and 85%, respectively, of the expected chondroitin. More shocking, two pet supplements had no detectable chondroitin despite a "guaranteed analysis" on the label of each showing significant chondroitin.

"The problem of 'missing chondroitin' is one that we first identified three years ago looking at products for human use," said Tod Cooperman, M.D.,'s President. "Most manufacturers seem to be doing a better job now with products for people, but pet owners seem particularly at-risk for getting ripped-off." In conjunction with its ongoing testing of supplements for human use, now intends to evaluate other popular types of pet vitamins and supplements.

The Review can be found at and includes results for 49 products, of which 6 are for pets. Twenty-six of the products were selected by and twenty-three others are included for having passed the same evaluation through's Voluntary Certification Program. The Review also provides information on how to best choose and use these supplements. Subscription is required for the full report.
