The Active Ingredient Is: Caffeine

Caffeine is basically a central nervous system stimulant and commonly used to help with alertness and energy levels [which is kind of just a nudge, not a magic cure]. This form comes from natural sources and is blended with other botanical components to support its role in energy and metabolism during activity.

What Does Caffeine Do?

Research shows caffeine ramps up energy burn and fat oxidation during workouts, contributing to metabolic activity. Dr. Astrup from the University of Copenhagen found that caffeine can boost heat production and fat burn in real-world tests.

These effects line up with guidance on energy metabolism and are seen with caffeine-containing blends that include different natural stimulants
