Ok, basically for the past month I've been working out with the football team getting ready for the 07 season. A few of the players on the team said they took something called creatine and it helped them get stronger. I've been skeptical of pills/shakes but these guys really did seem to get an increase in strength/muscle definition when they started using it.

That seems to be the most reliable site for information on it but I'm still confused about it.
What exactly does it do? Is it safe? Should I tell them not use it?
Also there seem to be so many different brands of it, which is the best?
Now I don't plan on using it because I'm not in favor of it but rather just curious about it because they are my friends and I don't want them getting hurt in the long run.
