The Active Ingredient Is: Caffeine Anhydrous

Caffeine anhydrous is a stimulant compound that gives central nervous system support to help boost energy and focus.

This form is delivered in a vegetarian capsule and is the main active ingredient in this product, with extra inert ingredients used for capsule delivery. The formulation is Halal certified and batch tested for quality.

What Does Caffeine Anhydrous Do?

In scientific contexts, caffeine acts as a central nervous system stimulant and can help maintain alertness and concentration, with effects on energy and endurance seen after intake.

Dr. Spriet from the University of Ottawa found that single caffeine doses can boost alertness and endurance performance, supporting the role of caffeine in sustaining mental and physical performance. This aligns with general guidance on caffeine’s role in energy and focus during activity.
