The Active Ingredient Is: Caffeine

Caffeine is a pick-me-up that occurs naturally in certain plants and is often used to boost alertness and cognitive energy.

This form comes from green coffee beans and is valued for its quick uptake and energising effects.

What Does Caffeine Do?

Caffeine helps spark alertness and focus and keeps attention during tough tasks. It blocks adenosine receptors, which may cut fatigue and boost metabolic activity.

The information reflects normal bodily function and is backed by well recognised energy metabolism and neural activity mechanisms.
