Question 3

How does Guarana work?

Accepted Answer

Stimulant Properties

The primary mechanism of Guarana involves its high concentration of caffeine. This compound acts as a central nervous system stimulant by antagonizing adenosine receptors. By blocking adenosine, which typically promotes relaxation and sleepiness, the ingredient helps maintain wakefulness and increases perceived energy levels.
