As I mentioned a while back, I’ve been doing a bit of running and, unsurprisingly, had knee problems. One response has been to take drinks made of a foul-tasting powder containing glucosamine sulphate and chondritin, which has been widely held out as having promise in relieving symptoms of osteoarthritis. There were some promising case studies, enough to prompt both widespread use, including by me, and a full-scale trial and meta-analysis.
The tests results are now in, and I have mixed feelings in reporting that the both glucosamine sulphate and chondritin appear to be useless. (H/T Neurologica, but link isn’t loading). I was tempted to finish off what was left, on the theory that it might be doing some good anyway, but my commitment to evidence-based policy, along with the fact that the stuff tastes foul, has prevailed.
Out it goes. Now, if anyone can recommend a good broad-spectrum placebo, I’m in the market.
