The EU has had studies that supposedly showed promising results however the doses used there are higher from what is used in American OTC doses. Also, no offense intended, at least one EU study has been discredited in the area of heart research recently.
Other problems with Glucosamine and Chondroitin are dose consistancy, label misrepresentation, and even impurities. Why it is that pharmaceuticals are held to such a high standard by the public yet these OTC's are not is beyond me.
On a personal level, as I type this, my wife who is a DC tells me that her subjective observations of her pt's are that neither of these two supplements are efficacious-
FWIW

If my memory serves, these supplements were first proven on horses for whom which the placebo effect is kinda hard to make happen.
Six months is not a very long study for soft tissue damage repair.
My next question is "peer reviewed" by whom? Think about this one before answering.
An observation I would make is this, because one area of study by the EU has been discredited then all areas of study by same are no longer valid? We could then throw out much of what any given area of science has concluded.
That last word is kinda big for a knifemaker...
