Anyone who says the cramps don’t exist can stuff it. They are there, at least for me, are unmistakeable and have occur every time I have tried it – at least 10 times, over the years. I keep thinking that maybe the cramps are a reaction to creatine insufficiency.

I have yet to see a study that included ‘normal’ people, as opposed to members of collegiate athletic teams or other high fitness groups and creatine. It may be that there is a difference there. But, for whatever reason, don’t doubt the cramps if you have them: plenty of other people experience them too, and they are unmistakeably due to the creatine.

One of creatines main benifits is that it lets your train longer and harder before your muscles become exahusted. Thus you can get extra muscle gains. As you list overtraining/overlifting as a cause of cramps it seems likely that creatine simply creates the ability for people to train longer icreasing the chances of overtraining and thus give themselves cramps.

Maybe creatine stops the body metabolizing sodium. I don’t think so though, I don’t think creatine is the cause or even makes it more likely. I’ve never had any problem during exercise with creatine more than wothout.
