Hi. I have advancing osteo arthritis: shoulders, hips, back, knees so far. I was wondering if anyone has had substantial success with any of the more "natural" products like Lyprinol, Lurosil, or Phosoplex? I have become overwhelmed with the claims of all the products out there, and I only get modest results from taking large doses of glucosamine/chondroitin/MSM capsules religiously every day. I am facing the prospect of eventual multiple joint surface replacements if I can't find a way to slow down the cartilage loss. Any stories of results (positive and negative) would be much appreciated.
