Background: The use of energy beverages is increasing in the general population and among military personnel. Although energy beverages contain a variety of ingredients, the main active ingredient is typically caffeine. Previous studies have reported discrepancies in the caffeine content of energy drink and dietary supplement labels and the actual amount of caffeine in the products. The possibility for intoxication/overdose is a concern if the caffeine content indicated on energy beverage labels deviates significantly from what the beverage actually contains. Objective: Examine the accuracy of caffeine content listed on the labels of various energy drinks and energy shots. Methods: Nine top‐selling energy drinks and five energy shots were chosen by using information from various sources. Three of each the 14 products were purchased and analyzed by an independent laboratory for caffeine content. Values from the laboratory reports were compared to the caffeine amount listed on the label. Results: Of the 14 products tested, three listed caffeine as ingredient but did not quantify it on their facts panel and two listed caffeine as part of a proprietary blend. The remaining nine products had caffeine amounts within 15% of amount indicated on the label, except one product, which was significantly lower. Conclusion: Although the caffeine content in the energy drinks and shots examined in this study were not accurately reflected on the labels, 64% were within acceptable ranges.
