The Active Ingredient Is: Caffeine

Caffeine is a central nervous system stimulant that supports mental alertness and exercise performance. It is a naturally occurring compound commonly found in coffee and tea and is used in concentrated forms to enhance readiness for demanding activity.

This form provides a potent, fast-acting source of stimulation and energy support, aligned with sugar-free, high-concentration pre-workout formulations designed to deliver rapid uptake during training.

What Does Caffeine Do?

Caffeine plays a role in increasing alertness and may contribute to greater endurance and metabolic activity during exercise. It also supports focused attention and delayed fatigue, in line with EFSA guidance on caffeine use for performance contexts.

In addition to these effects, caffeine is associated with enhanced fat oxidation and metabolic rate during activity, supporting broader energy utilisation during workouts.
