Caffeine has been found to improve physical performance, particularly endurance activities, as well as alertness, attention, and mood. Caffeine consumption has also been shown to decrease fatigue and improve reaction time. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4320759/
These studies provide evidence that caffeine can indeed be used to optimize mental and physical performance.
However, it is important to note that caffeine intake should be limited, as excessive consumption can lead to negative side effects such as anxiety, jitters, and elevated heart rate. It is best to consult a medical professional to determine the appropriate amount of caffeine intake for an individual’s needs.
