Summary

The line of "5-hour Energy"® products are available over-the-counter as energy supplements. The appeal of these products involves ease of use, low caloric value, and the absence of sugar to prevent a "crash" later in the day. The definitive efficacy and potency of the products is unknown due to the lack of evidence-based clinical reports. It is suspected that the efficacy related to these products is due to the caffeine content, which was reported as 138 mg per 2-ounce bottle in an online caffeine content chart. The purpose of this randomized, double-blind, placebo controlled, four way crossover study is to evaluate the efficacy of "5-hour Energy"®, "5-Hour Energy Decaf"®, caffeine, and placebo for perceived energy and wakefulness.
