The aim of this study was to compare the following aspects between junior- and senior-generation athletes to obtain basic data for future nutritional support activities for athletes, such as education on supplements and nutrition: the awareness of anti-doping; the type of supplements used; the frequency, purpose, and effects of use; the sources of information and access; and the inclination to buy. Although no association was found between dietary consciousness and generation, the awareness of anti-doping was lower in junior athletes. Differences between the two generations were also noted in the type of supplements used, the frequency and subjective effects of use, the source of information and access, and the inclination to buy. Therefore, generation-suited approaches should be considered for the education of elite athletes on supplements and nutrition.
