The Active Ingredient Is: Caffeine (Caffeine Anhydrous)

Caffeine acts as a natural stimulant that delivers a quick energy lift and boosts focus and mental alertness. This form, caffeine anhydrous, serves as a purified, concentrated source used in many pre-workout formulations.

It comes in its anhydrous state to help with rapid energy delivery and is used as a common stimulant element in sport nutrition items.

What Does Caffeine Do?

Caffeine helps lift alertness and reaction time and plays a part in boosting exercise power during tough workouts. EFSA and related guidance recognise caffeine as a contributor to normal energy metabolism and to less fatigue when energy production and performance are tested during exertion. This product isn't meant to diagnose, treat, cure, or prevent any disease.
