Caffeine bioavailability time-course after administration of caffeinated mouth spray

There is increasing interest in consuming caffeine through non-traditional methods, e.g., coffee and teas. Previous research has shown that caffeine appears in the bloodstream faster after chewing gum containing caffeine compared to swallowing caffeine pills. This suggests that caffeine can be absorbed faster through the mouth compared to digestion. However, it is unknown how caffeine appears in the bloodstream after using a mouth spray containing caffeine and how this compares to drinking commercial caffeinated drinks, such as coffee and energy drinks. This research will compare how quickly caffeine appears in the bloodstream after participants drink coffee or an energy drink or use a caffeine-containing mouth spray. The partner organization (VAE Labs) developed and sells the mouth spray commercially. Testing whether caffeine enters the bloodstream faster after using their mouth spray compared to commercial caffeinated rinks will be expected to benefit VAE labs as it will provide scientific evidence to support their product claims.
