Energy drinks (EDs) are gaining popularity every year with a broad consumer base including athletes, amateur competitors, and even those experiencing work-related fatigue. Evidence indicates that a significant number of individuals who consume EDs experience resultant morbidity and/or mortality, with a preponderance of cases involving teenagers and young adults. Adverse effects of ED consumption may occur in healthy persons, however certain individuals may be particularly susceptible to complications. At-risk populations include those of young age, the caffeine-naïve, or caffeine-sensitive, pregnant women, competitive athletes, and those with underlying cardiovascular disease. This paper summarizes the cardiovascular complications associated with ED use and provides suggestions on consumption of these drinks in various populations.
