It is a well known fact that caffeine and maltodextrin mouth rinses improve exercise performance, according to the authors:

Experiments, carried out as part of this study, were designed to find out whether there are additional benefits. See abstract below for the objective and results:
“Objectives: Caffeine (CAF) and maltodextrin (MALT) mouth rinses (MR) improve exercise performance. The current experiment aims at determining the effect of CAF and MALT MR on cognitive performance and brain activity. Methods: Ten healthy male subjects (age: 27±3yrs) completed 3 experimental trials. Each trial included 4 Stroop tasks: 2 familiarization tasks, 1 task before and 1 after MR. The reaction time (ms) and accuracy (%) of simple, congruent and incongruent stimuli were assessed. Electroencephalography was applied throughout the experiment to record brain activity. Amplitudes and latencies of P300 were determined during the Stroop tasks before and after MR. Subjects received MR with CAF (0.3gram/25mL), MALT (1.6gram/25mL) or placebo (PLAC) in a randomized, double-blind cross-over design. During MR, the brain imaging technique standardized low resolution brain electromagnetic tomography was applied. Results and discussion: Magnitude based inferences showed that CAF MR is likely trivial (63.5%) and likely beneficial (36.4%) compared to PLAC MR, and compared to MALT MR likely beneficial to reaction time on incongruent stimuli (61.6%). Additionally, both the orbitofrontal and dorsolateral prefrontal cortex were activated only during CAF MR, potentially explaining the likely beneficial effect on reaction times. MALT MR increased brain activity only within the orbitofrontal cortex. However, this brain activation did not alter the reaction time. Furthermore, no significant differences of the accuracy of the stimuli responses were observed between conditions. In conclusion, only CAF MR exerted a likely beneficial effect on reaction time due to the subsequent activation of both the orbitofrontal and dorsolateral prefrontal cortex.
What does this mean to you?
In simple terms, a dose of rinse - a little less than 1oz (25 ml) water containing 300mg caffeine - exerts a likely beneficial effect on reaction time, by activating the prefrontal cortex of our brains.
What does this mean to CaffeinAll™?
This is very good news to us, as our CaffeinAll™ is a blend of these two ingredients. So it’s incumbent upon us to evaluate it as a potentially useful component of mouth rinses, be they be self-prepared or pre-packaged - and that’s what we’ll do in the coming months.
We are thinking about putting together a home use test study. Let us know if you are interested. We’ll send you details, as well as a free CaffeinAll™ shaker, if you are chosen to be a participant!
