Personal note: I have taken glucosamine for a long time to ease arthritic joints. I ran out and did not have any for a week, and the joint pains came back in full force. Since I started taking it again, the joints have improved greatly. That's enough to convince me that it works. Your mileage may vary.

If you don't care for reality, just wait a while; another will be along shortly. --A Rose
