Do glucosamine and chondroitin work?

There was some previous research that said that glucosamine and chondroitin may provide pain relief. I am now hearing something different.

Dr. Allen D. Sawitzke, an associate professor of internal medicine at the University of Utah School of Medicine, has concluded that glucosamine and chondroitin are no better than a placebo at preventing cartilage loss in knees of people with the form of arthritis caused by wear and tear.

Ouch! That is pretty devastating news for all those people who have been popping these supplements in hopes that they might work.

The only good news in the study is that glucosamine may help some people with osteoarthritis.
