Hmmm, this thread has quite a bit of hostility.
My take on supplements is that they may work, and they may not. I've always been skeptical of them because most are backed by feelings rather than controlled studies. I'm also skeptical because many of the positive reports on them come not from the general public, but from people who stand to gain financially from them. When I do read reports from people who aren't connected to the supplement, it's quite common to hear them say essentially the same thing as the promoter. Many people want to believe...
So, if you think they will help you, and you have checked to be sure that they do not have any negative effects, go for it. Even if they don't actually do anything, just thinking they do (the placebo effect) might make you feel better. However, more important than any supplement is to eat a balanced diet, to establish and maintain a regular, and reasonable exercise plan, and to listen to your body.
