Supplementing potassium (citrate) hasn't helped me much, but works dramatically for Anna, Kevin, and Vassar.

I can't find mention of this on LW and the first few things Google turns up have to do with treating kidney stones, which doesn't seem relevant. What benefits do you get when this "works dramatically"?

About the same as drinking a cup of coffee - i.e., it works as a perker-upper, somehow. I'm not sure, since it doesn't do anything for me except possibly mitigate foot cramps.

Might be just placebo effect.

I don't have a reference at hand, but I recall hearing of a study where they gave the same sport drink to two groups of atletes and then measured their performances. Researchers told one group that they were testing a new, high quality super-duper sport drink, while they told the other group that it was a somewhat subpar product. Guess what happened to the performances of the two groups?
