They work well. Found this to be the best bargain here.
Very effective, no side effects.  These are large capsules.  Some might have difficulty swallowing them but, if so, just open them up and mix them with something.  The drugs are almost tasteless.  I have had cartilage removed from my knee and a bunionectomy.  I also suffer from osteoarthritis of my knees.  I found these very effective at easing my pain and increasing flexibility.  The glucosamine does NOT increase blood glucose levels.  Win-Win.  I found this to be the best bargain here on Amazon (when I bought) and far cheaper than Wal-Mart.
