Guarana Extract
A natural source of caffeine for sustained energy and mental focus.
Also known as: Paullinia cupana
Overview
Guarana extract is derived from the seeds of the Paullinia cupana plant, native to the Amazon basin. It is well-known for its high caffeine content, which is released more slowly than the caffeine from coffee, providing a more sustained and less jittery energy boost. In addition to caffeine, guarana contains other stimulants like theophylline and theobromine, as well as antioxidants.
