Caffeine

Caffeine is a naturally occurring stimulant most commonly found in coffee, tea, and various energy drinks. It is known for its ability to temporarily enhance alertness, reduce fatigue, and improve concentration. caffeine works by blocking the adenosine receptors in the brain, leading to increased neuronal firing and the release of neurotransmitters such as dopamine and norepinephrine. While generally safe in moderation, excessive consumption can lead to negative health effects.
