I highly recommend the Fresh Factors but after the last two weeks I'm not sure about the Joint Health. Both Isaac and Mizzy got sick. Huston -- no change. I've stopped the JH and returning it for Fresh Factors. I'll just add Whole Foods MSM.
Changes and improvements: much easier moving for them and not so achy. The majority of the people who have not seen improvement are not using enough chondroitin. In all the dogs I've tried it on, I've seen no further improvement when glucosamine is added.
If you are now confused, I'm sorry
