Supplements are not a shortcut to success and do not replace a well-planned periodized meal plan that meets the requirements of the athlete’s training program. In a few situations where supplements may provide a performance advantage, sports dietitians are encouraged to work with athletes and coaches to ensure protocols are achievable and effective.
The definitions and categorizations of dietary supplements are broad and can include products that provide practical sources of nutrients, address medical or clinical issues related to nutrient deficiencies, or achieve indirect or direct effects on performance. Sports dietitians should be well versed in the numerous ways of classifying dietary supplements and on the intended modes of use. They should also be aware of products that are sold or promoted as dietary supplements but are more accurately defined as pharmaceutical agents.
Sports dietitians should have an in-depth understanding of the safety, legality, and effectiveness of dietary supplements, which allows them to educate athletes to make informed decisions about use of dietary supplements.
Programs that include sports dietitians and other professionals as key gatekeepers to supplement access may provide a safe and supportive environment in which athletes follow evidence-based supplement practices, as opposed to unregulated use.
