Has anyone tried/use Glucosamine and Chondroitin? I bought some about three weeks ago, used it every day for two weeks. I can't tell for sure if it had any effect, so I'm wondering if longtime use would improve my chances.

I'm a "young" 46, but my shoulder sometimes aches terribly and pops, and knees grind when I bend them. (the oil can I borrowed from the Tin Man didn't help )

I saw a TV commerical about "Osteo Biflex", but when I went to Wally World, I found a very similar, lower priced product, so I bought it.

If anyone has used this stuff long term, has it worked for you?
Thanks a bunch, in advance.
