A third of osteoarthritis supplements fail quality tests; vitamin E fairs better.
ConsumerLab.com also found problems with four of the six animal supplements tested. One supplement sold in capsules contained only 17% of the claimed chondroitin. A chicken treat provided only 6% of the claimed glucosamine and only 16% of the claimed chondroitin. Each treat provided only about 1 mg of each of these two ingredients. Two different liquid supplements provided only 5.4% and 16% of the labeled amount of chondroitin, respectively.
Of 13 vitamin E products recently tested by ConsumcrLab.com, 10 met quality standards and FDA labeling requirements. While most supplements contained what they claimed, according to tests, two vitamin E oil products provided synthetic vitamin E when their labels suggested they were natural. One of these was also short on the total amount of vitamin E promised. Tests also showed that a vitamin E tablet failed to properly break apart, taking 128 minutes to disintegrate in solution rather than 30 minutes or less as required by the U.S. Pharmacopoeia (USP).
