This product was recommended to me by a friend who had the same issues with her legs/hips. The problem is not in walking, but in sitting/lying down. The joints stiffen and become very painful, then it is difficult to stand. The pain goes within a minute or so. Since starting to take this supplement, the pain has become much less severe, and I would recommend to anyone to try. A side effect I have noticed and welcomed is that my finger nails have become much stronger.
