The purpose of this report is to present the results of analysis of actual glucosamine
and/or chondroitin contents of several such products in the market place and to determine
if they significantly deviate from their label claim. A total of fourteen products containing
glucosamine sulfate and nine products containing chondroitin sulfate were evaluated. The
amounts of glucosamine and chondroitin were found to be significantly different from
the label claim in one product, ranging from as low as 59.00% to over 112.14% of the
lable claim for glucosamine and 77.69% to over 94.86 % for chondroitin. Retail price of
the product did not appear to be related to the quantity of active ingredients. The overall
results of this study show that famous brands are better candidates for counterfeiting than
expensive ones.
