Sports supplements. Can dietary additives boost athletic performance and potential?

Nutritional sports supplements, many of which are endorsed by professional athletes, are increasing in popularity among casual and adolescent sports enthusiasts, bodybuilders, and weight lifters.

Drs Rubinstein and Federman present an interesting overview of several sports supplements and examine the consequences and caveats of their use, as well as the reasons for their popularity.
