The Active Ingredient Is: Caffeine Anhydrous. Caffeine anhydrous is a purified stimulant used to help boost energy and alertness, and this dehydrated form is ready for use in supplements. This formula centres on caffeine anhydrous as the primary active ingredient, with additional botanical extracts that may enhance its metabolic and focus effects.

What Does Caffeine Anhydrous Do?

Caffeine anhydrous helps maintain energy expenditure and supports fat oxidation through acute metabolic effects. Scientific research indicates that caffeine intake can increase thermogenesis and fat breakdown, particularly when combined with botanical extracts used in this product.

Dr. Dulloo of the University of Lausanne found that caffeine acutely increases thermogenesis and fat oxidation, contributing to higher energy expenditure and supporting metabolic rate.
