Not certain if it is doing anything, but nothing getting worse.
I don't feel any worse, which could mean that it is preventing me from feeling worse, or that it's doing nothing.  But, I don't feel any better, either. However, because it could be restorative and preventative rather than simply palliative for pain, I will continue to use it (connective tissue disorder).  I use a similar product for my cat (vet brand), and it has an off label benefit of bladder health (according to vet).  Just an interesting tidbit, wonder if it works that way on humans.
