The Active Ingredient Is: Caffeine Anhydrous

Caffeine anhydrous is a boosting compound commonly used to support alertness and energy levels. It is a water-free form of caffeine that is rapidly absorbed by the body.

This form is derived from natural sources and is selected for rapid uptake to help deliver its effects efficiently.

What Does Caffeine Anhydrous Do?

Caffeine helps maintain energy expenditure and supports mental focus in line with EFSA guidance, with evidence suggesting acute caffeine intake can boost energy use during activity. This line of research from Dr. Astrup at University of Copenhagen shows acute intakes of caffeine lift energy expenditure and fat oxidation, especially around exercise
