ConsumerLab.com, White Plains, NY, has released test results for supplements used in treating osteoarthritis that contain glucosamine, chondroitin and/or MSM. Several combination products were found to be low in chondroitin. Two products for use by people contained less than 20% and 85%, respectively, of the expected chondroitin. In addition, two pet supplements had no detectable chondroitin despite a “guaranteed analysis” on the label of each showing significant chondroitin.
