The Active Ingredient Is: Caffeine

Caffeine is a natural stimulant that supports mental alertness and perceived energy during activity. It is a central nervous system stimulant commonly used in beverages and supplements to help combat fatigue and maintain focus.

This form is a widely used stimulant that can be consumed in various products to support acute energy needs and alertness during physical effort.

What Does Caffeine Do?

Caffeine aids in increasing alertness and reaction time and may support endurance during exercise at typical performance doses.

Dr. Grgic of the University found that a 200 mg dose improves alertness and endurance, aligning with EFSA and NHS interpretations of caffeine’s role in maintaining energy during activity.
