Depends
I was having trouble rating this product, as it didn't help me at all, but my mother is saying it did help her a lot. She's 85, and got severe arthritis in her knees, very painful to walk, and the pain is much easier now - she's already in her third jar.<br />However, I've also got knee pain, probably of different nature (inflammatory) - one jar hasn't changed it a bit for me, so I just quit.
Rating: 4 stars
