Caffeine and Guarana
NCAA Drug Testing Fact Sheet for Student Athletes – Caffeine and Guarana
November 16, 2022
College athletes need to be careful when it comes to caffeine and guarana since they are on the NCAA Banned Substances list. While moderate amounts of caffeine can improve athletic performance, too much can actually hurt athletic performance. Overload on caffeine and you will be too anxious and jittery to play and can permanently impact your athletic career if you test positive. While many student athletes use caffeine daily and don’t test positive, it is possible. Here is what student athletes, parents, coaches and others need to know about caffeine, guarana, and NCAA drug testing.
- Caffeine is not banned outright by the NCAA, rather it must be limited. To test positive for caffeine in the NCAA there must be more than 15 micrograms per milliliter (ug/ml, parts per million) found in a urine sample. [i]
- It takes 500 mg of caffeine to reach the 15 ug/ml caffeine limit according to the U.S. Olympic Committee, Sports Cardiovascular and Wellness Nutrition (SCAN), Collegiate and Professional Sports Dietitians Association (CPSDA) and NCAA Sport Science Institute. [ii] [iii] Metabolism can vary and less may be a concern for some people.
- A statistical study in 2019 looked at caffeine levels in 7,844 urine samples from elite athletes and showed less than 0.87% violated the old World Anti-Doping Agency (WADA) threshold of 12 ug/ml. [iv] If this carries over to the NCAA where caffeine is banned at a higher limit of 15 ug/ml the positive rate may be even lower.
- A 2021 International Society of Sports Nutrition (ISSN) position stand on caffeine and exercise performance noted, “10 mg/kg body mass orally ingested over several hours,” is needed to break the 12 ug/ml caffeine limit in Olympic drug testing. [v] At 4.55 mg/lb this corresponds to 500-1,365 mg for athletes in the 110-300 pound range.
- The CPSDA, SCAN, NCAA Sport Science Institute, and ISSN agree that 3-6 mg/kg body mass of caffeine can improve exercise performance while 6-9 mg/kg can lead to “overstimulation” and other negative side-effects.
- FDA caffeine guidelines, “cited 400 milligrams a day—that’s about four or five cups of coffee—as an amount not generally associated with dangerous, negative effects.” [vi] This is also below the suggested NCAA risk level.
- Guarana is on the NCAA Banned Substances list only as an example of caffeine; guarana is not completely banned. Consumption of guarana must be limited along with the more than 60 other plant sources of caffeine including coffee, tea, cocoa, yerba mate, kola nut, and guayusa. [vii] [viii]
- NCAA drug testing does not check for any of the specific sources of caffeine like guarana, coffee, tea, or chocolate. The NCAA tests for caffeine itself in high amounts greater than 15 ug/ml in urine.
- Energy drinks containing caffeine or guarana are impermissible for NCAA schools to provide to student athletes under NCAA Division I Bylaw 126.96.36.199 Nutritional Supplements, but they can still be consumed in moderation. [ix] Excessive use of any product or food containing caffeine can put student athletes at risk of a positive drug test.
- Popular energy drinks like Celsius, Monster, Rockstar and others that contain caffeine and guarana are not totally banned by the NCAA. Energy drink brands cannot have sponsorships with the NCAA or any schools but can be name, image, likeness (“NIL”) sponsors of individual athletes.
- Some varieties of Vitaminwater, like Energy, include caffeine and guarana, a 2009 NCAA press release confirmed that “normal daily consumption of any of the 13 Vitaminwater varieties will not place a student-athlete at risk for testing positive for banned substances.” [x]
