The Active Ingredient Is: Caffeine

Caffeine is a natural stimulant that exists in plants and is commonly used to support wakefulness and focus. This ingredient is typically sourced from green coffee beans and is a key energy-boosting part in many products.

This form is derived from green coffee beans and plays a central role in delivering quick, sustainable energy and mental alertness.

What Does Caffeine Do?

Caffeine helps boost alertness, attention, and cognitive performance. Dr. Smith from Harvard University found that caffeine can enhance these functions, which aligns with evidence on its effects on mental performance.

The combination of caffeine with cognitive-support nutrients in this kind of product is discussed in EFSA and NHS contexts as supporting normal mental function and alertness during daily activities.
