I take um....this stuff when I can remember and I think it helps. Two pills once a day. Easy enough. 1500 mg of glucosamine in that, plus 1210 mg of their "proprietary blend" that includes chondroitin, HA, MSM, collagen and some other stuff. It's cheap, too.
I take 2-1000 mg tablets of GNC Vegetarian Glucosamine (no Chondroitin) and 1000 mg of Rite-Aid Brand MSM every morning. With it I am mostly pain free, without it my right knee blows up and I can hardly walk.
