Osteoarthritis is the most common type of arthritis. Supplements made with glucosamine, chondroitin, and/or MSM may reduce symptoms by helping to maintain and repair cartilage. These products have become top selling supplements.
But eight supplements for osteoarthritis failed ConsumerLab's testing. Four had less than 8% of their listed amounts of key ingredients, including a "maximum strength" product that contained no chondroitin at all. Three others had only 52% to 75% of listed ingredients. One failed because it would not properly break apart to release its glucosamine and chondroitin.
In this Review, you'll get ConsumerLab's test results for thirty-seven glucosamine, chondroitin, and/or MSM supplements and information about five products similar to those tested. The report even includes pass/fail results for five supplements for pets. We'll tell you what to look for and what to look out for, so you'll understand the potential benefits and risks of these popular and potentially useful supplements.
