So, what is in a label?
An April 2000 study published in the Journal of the American Nutraceutical Association reports that 27 out of 32 (84 percent) products tested contained less than 90 percent of the amount of chondroitin sulfate stated on the label.
While the study did not list specific product manufacturers, it did find that products with a standard retail price of less than or equal to one dollar per dose of 1200mg of chondroitin sulfate were seriously deficient in meeting label claims. In fact, the study also reports that deviations from label claims ranged from 0 percent to 115 percent.
Nutramax Laboratories went on the offense after release of the study citing that manufacturers' quality control efforts are critical. So much so, the company says that it has taken substantial measures to voluntarily police itself, including independent testing review of its raw materials and finished products.

"Overall, nearly one-third of the products did not pass testing. Among glucosamine/chondroitin combination products, however, almost half (6 out of 13) did not pass — all due to low chondroitin levels. Similarly, the two chondroitin-only products tested did not pass. In contrast, all ten of the glucosamine-only products passed testing. One possible explanation for the low pass rate for chondroitin-containing products is economic — chondroitin costs manufacturers approximately four times as much as glucosamine."
