Most participants in the study had mild knee pain. Those who received the prescription drug had better short‐term pain relief (at 6 months) than those who received aplacebo. – Overall, those who received the supplements had no significant improvement in knee pain or function, although the investigators saw evidence of improvement in a small subgroup of patients with moderate‐to‐severe pain who took glucosamine and chondroitin together. – In several European studies, participants reported that their knees felt and functioned better after taking glucosamine. The study participants took a large, once‐a‐day dose of a preparation of glucosamine sulfate (Rottapharm) sold as a prescription drug in Europe. – In general, research on chondroitin has not shown it to be helpful for pain from knee or hip osteoarthritis. http://nccam.nih.gov/health/glucosaminechondroitin 13 Glucosamine for osteoarthritis • A few studies have looked at whether glucosamine or chondroitin can have beneficial effects on joint structure. Some but not all studies found evidence that chondroitin might help, but the improvements may be too small to make a difference to patients. There is little evidence that glucosamine has beneficial effects on joint structure. • No serious side effects have been reported in large, well‐conducted studies of people taking glucosamine, chondroitin, or both for up to 3years. • However, glucosamine or chondroitin may interact with the anticoagulant (blood‐ thinning) drug warfarin (Coumadin) and also the way your body handles sugar, especially if you have diabetes or other blood sugar problems, such as insulin resistance or impaired glucose tolerance.
