What does it do?

Caffeine is an alkaloid compound found in nature, primarily used in pharmaceuticals to stimulate the central nervous system. It helps in recovery from fatigue and enhances concentration, used to maintain a state of wakefulness.

Caffeine blocks adenosine receptors in the brain, suppressing signals that induce drowsiness. As a result, the central nervous system is activated, reducing feelings of fatigue and clearing the mind.

Approved uses differ by product. Check each product's information for its actual use.
