From the guayusa leaf. USDA organic. We call it clean because it's natural energy from a single ingredient: the guayusa (gwhy-you-sa) leaf. Most energy drinks are a cocktail of hard-to-pronounce chemicals. This is just a hard-to-pronounce leaf brewed strong, the way Amazonian tribes brew it before sunrise to feel runa - meaning fully alive. Since it's naturally caffeinated and balanced with polyphenols, you get sustained energy and focus without feeling a crash. It's organic clean energy from a leaf, not a lab.
