The Active Ingredient Is: Guarana Seed Powder

Guarana seed powder is a plant-derived extract used for its phytonutrient content and traditional energy-support role. This whole-seed form provides a spectrum of components from Paullinia cupana that contribute to the product's energising profile.

This form is sourced as a full spectrum seed powder, meaning it reflects the natural composition of the seeds and their accompanying bioactives rather than a single isolated compound.

What Does Guarana Seed Powder Do?

Guarana seed powder participates in supporting alertness and concentration through its caffeine content, which stimulates the central nervous system. It also contains other plant compounds that may contribute to its overall profile.

Educational guidance from health bodies notes caffeine-containing substances can support wakefulness and daily cognitive function within normal use, aligning with EFSA and NHS perspectives on routine energy and focus support.
