I think some brands may work a little better than others
I try to take 1-2 Glucosamine Chondroitin MSM pills everyday, especially when I start running or exercising. I usually cannot run without my ankles, knees, hips, and/or sometimes my neck hurting.  When I take the glucosamine chondroitin, I notice a huge difference with my joints. I think some brands may work a little better than others, but as long as I'm taking one of them, it helps.  I've recommended this to my family and anyone who tells me they have joint pain.
