What Works for Joint Health? ConsumerLab.com Reviews Glucosamine, Chondroitin, MSM and Boswellia Supplements for People and Pets

White Plains, New York, June 3, 2016 — Do popular joint health supplements with ingredients such as glucosamine, chondroitin, Boswellia, and MSM really work to relieve pain or slow the progression of osteoarthritis? And, with so many to choose from, which supplements are best? To find out, ConsumerLab.com recently tested 30 popular joint supplements for people and 6 supplements for pets to see whether they contained their claimed amounts of key ingredients without contaminants and would disintegrate properly.

Twenty-seven percent of people who take multiple dietary supplements take a joint health supplement, according to the latest ConsumerLab.com consumer survey.

Among the 16 products for people which ConsumerLab.com selected and tested, most contained what they claimed, as did fourteen additional products tested through CL's voluntary Quality Certification Program. However, one product contained just 50.4% of the Boswellia promised on the label, based on its content of boswellic acids. Other products listed a dose far smaller than what has been shown to work, or hid amounts of important ingredients within "proprietary blends." Among the products Approved for Quality in the tests were then compared on price to show which offer the best value.

Among the four products for dogs and cats which ConsumerLab.com selected and tested, only one met quality standards. A product which claimed to contain chondroitin was found to contain none, while another was found to contain only 8% of its listed amount. A third product was contaminated with arsenic. Two additional pet products which were tested through CL's voluntary Quality Certification Program met quality standards and were Approved for Quality.
