Caffeine is known for its stimulating effect on psychological and physiological functions.
One of caffeine’s primary sites of action is the central nervous system. Amongst others caffeine consumption increases alertness, reaction speed, vigilance, the ability to concentrate and problem-solving ability. Further, it decreases mental fatigue.*
Caffeine also stimulates fat burning during endurance activities. Thereby it helps to use fat stores in the body for providing energy and preserving the glycogen (=sugar) stores. This means that caffeine intake during endurance activities results in a more efficient supply of energy, especially in extended exertion it leads to significant improvement in performance and endurance.**
