Just use the Kirkland Signature Glucosamine and chondroitan supliment. The 1500/1200. My wife and i use them. She has bad knees, and i have a bad hip. Cut the pain down well over 50%. About $20 a bottle for a 70+day supply (for one person)
My doc says there is more and more proof that it works. Better for hips and shoulders than knees though. I am seeing an arthritis specialist tomorrow and will ask him as well.
