serving of Red Bull is 81 mg). Recommendations While clear-cut recommendations for athletes do not exist, some groups such as the Mayo Clinic do not recommend energy drinks for athletes participating in exercise lasting less than 1 hour (15), but also admit there is a lack of long-term data to support this conclusion. Even when consumption of an energy drink results in a statistical increase in performance, this translates into a very small real-world change; it will not transform anyone into the next Olympic athlete overnight. The main ergogenic ingredient (caffeine) has a great safety record when used in moderation. The longest-term data available in the literature on one type of energy drink (Celsius) taken once a day for 10 weeks did not show any change in clinical markers for hepatic, renal, cardiovascular, or immune function, and revealed no adverse effects in response to its consumption (21). Unfortunately there are not any other data investigating other types of energy drinks for a similar length of time, especially accounting for a higher total dose and frequency. Based on current data, it appears that an occasional energy drink with regard to acute health risks is safe; but long-term studies have not yet been conducted. Source: NSCA
