There is a good (at least it appears so to me) overview of mainstream nutritional supplements for athletic performance in this article from the current (Feb 8, 2016) of 'Chemical and Engineering News' from the Amercan Chemical Society.
It is somewhat unusual to see an article of this type outside of a 'jock magazine' or a scientific journal.
It might be a useful resource as an introduction to supplements for people who are dubious about their value.
