Caffeine, a natural stimulant found in coffee, tea, chocolate, and other plants, is the world's most popular psychoactive substance. It provides a temporary energy boost and combats fatigue by stimulating the central nervous system.

Caffeine offers a range of health benefits. It increases alertness, improves focus, and provides a temporary energy boost by stimulating the central nervous system. Athletes often turn to caffeine to enhance physical performance, as it improves endurance, reduces fatigue, and increases heart rate through the release of adrenaline. Furthermore, caffeine enhances cognitive function, including attention, memory, and reaction time. It can also positively impact mood by stimulating the production of neurotransmitters like dopamine and serotonin, which contribute to feelings of happiness and well-being. These effects make caffeine a popular choice for those seeking increased alertness, improved performance, and a positive mood boost.
