There are many good studies which indicate glucosamine is more effective than a placebo in decreasing pain and / or increasing function for people with chronic joint conditions. (See Research)
In my experience it does not work for everyone but it is worth trying.
My advice is to give your sore area a score out of 10 every day for a week before you you start taking Glucosamine. Hide the scores!
Commence the recommended dose for three months and then repeat the scoring process. Most people know if Glucosamine is helping but sometimes the average score is lowered surprisingly. If there is no change in your scores then you may as well not buy it. Good luck!
