It will really help with the knees. That's what I take it for since I've got teflon in both of them and it's pretty old.

so i got some glucosamine something with mgm or something like that... ill see how that works in a few weeks i guess... i only started worrying about this because recently it went from sore muscles after riding to sometimes a shooting pain down my spine or grinding knees...Yup I use that stuff too. And it's MSM, mgm is a movie company It'll take a few weeks (up to six) to really notice a difference, so don't get discouraged. Plus if you stop taking it for even a short time the start up can take just as long so don't forget to take it regularly. My left knee hurts after I went down on Palomar about 5 years ago, that and strong legs, and stretching help the most. I have arthritis now, so icing then only makes them hurt. But heat helps to relax them a bit, but be careful if they are a bit weak, then relaxing them can actually make them twist easier because the muscles can't hold the knee together.

Yeah, ya gotta keep taking it for it to do any good.
