A large NIH study hit the headlines this fall because of the disappointing effect of Glucosamine on knee pain. The Prescriber’s Letter pointed out that that study used the hydrochloride form of Glucosamine. Several other studies using the sulfate form showed significant benefit in osteoarthritis. This is another example of how special interests (drug manufacturers) get to the media to put their twist on scientific evidence to distort it and maintain their profits.
