I tried posting a thread like this about a year ago, but it didn't really go anywhere, I'm hoping with some new knowledge/new blood on the forums we can make something of this. Basically, I'm free of joint problems right now, but I want to make sure I stay that way so I can keep training well into the future. How can I further this cause through nutrition and supplementation? Here's some thoughts to get things started: Glucosamine/Chondroitin/MSM: Seem effective in treating joint pain, but can they work at all in a preventative capacity? Calcium: I've never thought supplementation was necessary for someone who sticks to a sound diet, am I wrong here? Should athletes be supplementing additional calcium? Cissus: Lots of anecdotal evidence of effectiveness, but the fact that no one knows HOW it works and the fact that it involves some sort of hormonal action bothers me somewhat. Shark Cartilage: Basically comes down to additional calcium and phosphorus, right? Fish Oils (Omega-3s): I think the verdict is pretty much in on these. Pretty sure we're all taking them already.
