Podcast 101: Osteoarthritis, chondroitin, and glucosamine — one of these things doesn’t belong.

Answer: Osteoarthritis. Two are nostrums and the other is a disease, but the nostrums have no appreciable effect — on osteoarthritis at least. We discuss a BMJ meta-analysis that uses novel methods to prove the point.

The good news is that neither chondroitin nor glucosamine is dangerous, but the bad news is that we spend so much hoping that this is the right combination to alleviate arthritic pain.
