The Active Ingredient Is: Caffeine

Caffeine is a handy central nervous system stimulant that helps you feel alert and ease fatigue you notice. In this formula it's present as caffeine anhydrous, a commonly used form for quick uptake and steady effects.)

What Does Caffeine Do?

Caffeine helps raise energy and focus, keeps you awake and aware. It plays a role in reducing perceived exertion during activity and may help with endurance during high-intensity exercise. This understanding is reflected in EFSA and NHS guidance on caffeine use for physical performance. This is true for daily use, and it’s a reference point many athletes rely on when planning training sessions.
