Study 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.
Primary Outcome
Subjects are provided with assessment tools to use for each product. The tool contains the Stanford Sleepiness Scale to assess for wakefulness levels. All appropriate options are listed, and subjects are required to circle one option at one, three, and five hours after taking the study product for the day.
Interventions
- OTHER Regular "5-hour Energy"
- OTHER Decaf "5-hour Energy"
- OTHER Compounded concentrated caffeine liquid
- OTHER Flavored bottled water
