Is there a good natural supplement for arthritis?

Natural Exercise. Perhaps not the answer you wanted to hear but for many types of arthritis specialized exercises can help. Some people have felt glucosamine and chondroitin can help osteoarthritis, but not everyone with osteoarthritis responds. It can depend on the dosing and quality since these are "over the counter medications" and the fda does not evaluate these products like they do prescription meds.
Yes. Glucosamine and chondroiton combined in one supplement has shown significant promise for arthritis in many orthopedic studies, and especially in veterinarian arthritis studies. Our fda says it is a placebo. Not all mds agree with this conclusion.
