                                According to a 2017 U.S. survey, chondroitin (often paired with glucosamine) was one of the most popular supplements for osteoarthritis sufferers. However, despite its widespread use, there are several key reasons not to take glucosamine chondroitin, especially for those with certain health conditions or allergies.
