Clinical Studies
Caffeine has been widely studied for its effects on mental alertness and physical performance. A study published in the Journal of Applied Physiology found that caffeine consumption enhances endurance and reduces perceived exertion during exercise, making it a popular choice among athletes. Another study in Psychopharmacology demonstrated caffeine's ability to improve cognitive performance, including attention and reaction time, especially during prolonged periods of activity.
