Journal ArticleDOI
The use of dietary supplements and medications by Canadian athletes at the Atlanta and Sydney Olympic Games.
TL;DR: Widespread use of supplements is demonstrated among Canadian athletes at both the Atlanta and Sydney Olympic Games, combined with an absence of evidence of their efficacy and a concern for the possibility of “inadvertent” doping, underscore the need for appropriately focused educational initiatives.
