The Active Ingredient Is: Caffeine Anhydrous

Caffeine anhydrous is a kickstart that nudges the brain system to boost alertness and focus during activity.

This form tends to soak up quickly and is tucked into this product with energy-boosting carriers and electrolytes to help steady performance during endurance sessions [for daily training].

What Does Caffeine Anhydrous Do?

Caffeine anhydrous helps reduce perceived effort, pushes fatigue back a bit, and supports sharper focus and wakefulness through long workouts. These effects sit in the frame of endurance research done at university level.

Dr. Spriet at the University of Ottawa showed caffeine can boost endurance and mental alertness during long activity, which fits EFSA and NHS notes on normal energy metabolism and thinking function.
