“…Their results show that the mean prevalence of supplement use among athletes was 46 %. Approximately the same percentage was found for adolescents and high-school athletes (Bell et al 2004;Sobal & Marquart, 1994b). It is not known whether prevalence of use varies widely between the sexes.…”

Based upon recent sales numbers, nutritional supplements play a key role in the lifestyle of a substantial proportion of the population. As well as products such as vitamins or minerals, several precursors of anabolic steroids are marketed as nutritional supplements. Another group of commercially available supplements are products for weight loss based upon herbal formulations originating from Ephedra species. Apart from supplements indicating the presence of these active compounds, numerous non-hormonal nutritional supplements were found that were contaminated with non-labelled anabolic steroids. Stimulating agents other than naturally occurring analogues of ephedrine were detected. A major group using dietary supplements are sportsmen, ranging from amateur level to elite athletes. Besides the possible health risks associated with the use of dietary supplements, athletes should take care not to violate the rules of the World Anti-Doping Agency because athletes remain responsible for substances detected in their biofluids, irrespective of their origin. Several analytical methods have been developed to determine the presence of doping agents as contaminants. The present review attempts to address the issues concerning the use of nutritional supplements and the detection of doping agents as contaminants in dietary supplements.

“…For example, research on adolescent ergogenic supplement use has shown that lack of knowledge makes adolescents more susceptible to misinformation from peers, trainers and marketers (Bell, Dorsch, McCreary, & Hovey, 2004). Therefore, failing to provide knowledge about negative health consequences, results in adolescents with knowledge deficits that can make them more susceptible to misinformation than adolescents with accurate knowledge about negative health consequences.…”

“…While deficits in actual knowledge about negative health consequences can make adolescents susceptible to misinformation (Bell et al, 2004;Laure & Binsinger, 2005), work by Goldberg and colleagues (2003) demonstrate that the more negatively an adolescent perceives the consequences of AS misuse, the less likely they are to use. Together these studies imply that prevention efforts should do more than alter adolescents' perceptions about negative health consequences associated with AS misuse, as such perceptions may or may not be based upon accurate knowledge (Bell et al, 2004;Laure & Binsinger, 2005).…”
