It works!
I have been taking Hyaluronic Acid for my shoulder pain, and it works great. However, I started developing a nagging pain in my left thumb that wouldn't go away. After a month of dealing with the pain, hoping it would go away, I ordered the glucosamine sulfate potassium powder. After about a week, I noticed I didn't have any more pain, and have been pain free ever since. I highly recommend this product!
