Prevalence of dietary supplement use among male Brazilian recreational triathletes: a cross-sectional study.

BACKGROUND AND RATIONALE: The literature shows that the prevalence of dietary supplements is high and guidance by a nutritionist or specialized professional is low in professional triathletes. It is reasonable to assume that in recreational triathletes, the prevalence of dietary supplements will also be high and that a significant portion of the sampled population will use supplements without any guidance from a qualified professional. The present study investigated dietary supplement use among Brazilian male recreational triathletes.

METHODS: A total of 724 Brazilian male recreational triathletes (age: 38.00 [10.00] years and body mass index: 24.16 [3.02] kg/m2 ) took part in this study. All participants answered an online questionnaire containing questions about their demographic characteristics and the nutritional aspects of their diet.

RESULTS: The results showed that ~ 90% (n = 653) of the interviewed participants reported using at least one dietary supplement. Surprisingly, ~ 25% did not receive supplement advice from a professional nutritionist.

CONCLUSION: The prevalence of dietary supplements in male recreational triathletes was high, and a substantial part of the sample did not receive professional recommendations. This situation is worrisome because dietary supplements should be prescribed by a professional nutritionist.

PRACTICAL IMPLICATIONS: Our results suggest the need for an appropriate attitude and guidance by health professionals who deal with this population, especially nutritionists, to promote safe practices.
