Natural Caffeine: The Clean Stimulant
Caffeine is a plant alkaloid that acts as a central nervous system stimulant. It works by blocking adenosine receptors in the brain, adenosine being the neurotransmitter that signals fatigue. By doing so, caffeine increases alertness, reaction time, and perceived energy.
But not all caffeine is created equal. Natural caffeine, especially from green tea, is absorbed more gradually and is often accompanied by compounds that modulate its effects, making it smoother and more sustainable.
