Caffeine also stimulates cortisol secretion, particularly at higher doses, aiding in energy mobilization during stress and exercise.Energy drinks and pre-workout supplements containing caffeine have been demonstrated to enhance both anaerobic and aerobic performance.Caffeine is perhaps the most readily available stimulant in the world, yet the NCAA and the International Olympic Committee (IOC) consider it a “controlled or restricted substance.
