Because of concerns regarding the cardiovascular safety of energy drinks, products such as Red Bull (RB) have been banned in some countries; however deleterious cardiovascular effects have not been well documented. Fasting human subjects (aged 19.8 ± 1.6 years; 47 = female; 21 = male) were randomly selected to receive a single 250 ml serving of RB (110 Cal; 110RB), Sugar Free RB (10 Cal; 10RB), 110 Cal placebo (110CP) or 10 Cal placebo (10CP). Blood pressure, EKG, blood glucose, urine formation rate, and saliva caffeine content were evaluated prior to beverage administration, then 60 and 120 minutes postprandially. Saliva caffeine content was significantly increased only following 110RB and 10RB. RB did not significantly affect urine specific gravity or formation rate, nor did it affect plasma glucose, heart rate or blood pressure. A 30 second EKG was evaluated for arrhythmias, QT‐interval, and RR‐interval, but RB was found to have no effect. Administration of a single serving of RB did not cause any observed deleterious effects. Further studies may need to characterize the physiological effect of larger doses of RB or interactions with other dietary materials such as alcohol.
