The Active Ingredient Is: Caffeine

Caffeine is basically a stimulant that helps to support energy and mental alertness as part of normal bodily function.

This form is often used in pre-workout blends to deliver quick energy and focus before activity.

What Does Caffeine Do?

Caffeine helps with energy and alertness, and plays a role in supporting peak power during workouts.

Dr. Glaister of the Journal of the International Society of Sports Nutrition found that caffeine significantly enhances exercise energy and alertness, aligning with EFSA guidance on energy metabolism and performance [which many users find reassuring].
