Dietary Supplements for Athlete Safety & Performance — NATA 2026 Recap
Hi everyone, Along with @Floriswardenaar and @DanaWhiteNutrition , I had the chance to present "Evaluating Dietary Supplements for Athlete Safety and Performance" at NATA 2026, and wanted to bring the conversation here since supplement questions come up in the athletic training room almost daily. Why this matters: the grand majority of competitive athletes are using supplements in some form — multivitamins, sports drinks, protein powders, caffeine, creatine — and on average athletes report using around four different products. But supplements aren't premarket-approved by the FDA (DSHEA puts the burden on manufacturers before sale, with FDA/FTC enforcing after the fact), so adulteration and spiking are real risks. Studies estimate roughly a quarter of supplements carry some risk of unintentional doping, and dietary supplements have been linked to a meaningful share of doping violations over the years. Practical framework for reviewing a product with an athlete — "Is it Safe? Is it Legal? Does it Work?" Is it safe? Is it third-party tested? Not all certifications are equal — a "certified" label doesn't automatically mean it's been screened for banned substances, so know the difference between quality-control certifications and sport-specific banned-substance testing (NSF Certified for Sport, Informed Sport, BSCG, HASTA, Cologne List, NZVT). Check for known side effects/interactions using Examine.com , ConsumerLab , or the Natural Medicines Database . Report adverse events at www.safetyreporting.hhs.gov . Is it legal for your athlete's governing body? Olympic/Paralympic/Pan Am athletes: WADA Prohibited List ( wada-ama.org ) and GlobalDRO.com to check medication status. Collegiate athletes: current NCAA Banned Substances List . Pro leagues (NFL, NBA, MLB, etc.) each have their own PED policies negotiated with their players' unions — don't assume NCAA/WADA rules apply. Does it work? The Australian Institute of Sport (AIS) Supplement Framework (ABCD classification) is a great starting point for grading evidence — Group A (sports foods, medical supplements, and performance supplements like caffeine, beta-alanine, nitrate, creatine) has the strongest support; Group D is banned/high contamination risk. A practical, real-world example: if an athlete is choosing between Pre-workout/caffiene products, it's worth knowing that some mainstream options do carry NSF Certified for Sport status — for instance, Gatorade's Fast Twitch is NSF Certified for Sport. Tell your athletes to check specific products against the NSF Certified for Sport or Informed Sport Database BEFORE purchasing. Bottom line: ATs and Sports Performance Coaches are often the first point of contact when an athlete asks "can I take this?" You don't need to be the supplement expert — but knowing this framework, and knowing when/how to loop in a sports RD, protects both the athlete's health and their eligibility. Heads up: a full peer-reviewed article on this exact topic is set to publish in the Journal of Athletic Training this August. I'll come back and link it here once it's live — it'll have more detail than we could fit into the NATA session. What’s showing up on your desk?? Is it mostly creatine and protein questions, or are athletes coming to you with riskier stuff like pre-workouts and "fat burners"? And where do you get stuck: identifying what's actually in a product, figuring out if it's legal for your athlete's level, or something else?
