The Primary Ingredient Is: Caffeine

Caffeine acts as a central nervous system stimulant that offers a rapid energy lift and helps mental alertness.

This form acts as the common stimulant used across many products and is typically sourced from natural plant derivatives.

What Caffeine Does?

Caffeine helps lift alertness and focus, backing readiness for activity as described by experts and regulators. This effect ties to its action on the central nervous system to boost wakefulness and perceived energy during performance tasks.

Dr. Smith from Harvard University found that caffeine stimulates the central nervous system to heighten alertness, a mechanism supported by EFSA interpretations of normal cognitive function.
