Caffeine is a core nervous system booster that helps sustain alertness and mental focus.

This variant is caffeine anhydrous, a pure powder form used in energy drinks to deliver rapid, portable stimulation.

EFSA notes caffeine boosts alertness and focus at doses of 75mg and higher, with steady gains in exercise performance seen at 200mg and above.

In this formula, caffeine helps to maintain sustained focus during demanding activities and supports short-term energy availability, which can be relevant for athletes and active individuals (which matters).
