Caffeine is a stimulant that jolts the nervous system to boost alertness and energy. It’s commonly consumed to help focus and performance during tough activity [which helps you push through].

This blend draws caffeine from eight different sources, including green tea, yerba mate and guarana, giving a steady energy profile through several natural inputs.

What Does Caffeine Do?

Caffeine contributes to heightened alertness and can help delay fatigue during tough, high-intensity efforts. Dr. Spriet from the University of Guelph found that caffeine boosts performance and lengthens exercise capacity in trained individuals.

The mix of caffeine with the other performance ingredients supports focus and energy during training, aligning with typical physiological responses to stimulants.
