Description
Caffeine is a naturally occurring stimulant present in coffee beans, tea leaves, cacao, and select botanical sources. Classified as a xanthine alkaloid, it engages with neurotransmitter systems by modulating adenosine receptors, influencing wakefulness, cognitive function, and neural signaling. Furthermore, caffeine supports metabolic pathways involved in energy production and thermogenesis. It also influences physiological responses linked to mental focus and endurance. As a widely consumed bioactive compound, caffeine remains an essential element in both traditional and modern dietary habits.
