Guarana is a creeping shrub native to the Amazon rainforest that produces clusters of small bright red fruit, the seed of which has been used by indigenous tribes for centuries to help to reduce mental fatigue and to help maintain mental awareness. It gains its energizing benefits from a number of actives that are found in the seed. These include caffeine and two other stimulants - theophylline and theobromine. These stimulants are found in a complexly named guaranine that provides gentle stimulation over a period of several hours without the peak and trough in energy that is associated with many sources of caffeine. This powder is ideal for use in punches or in smoothies. Alternatively.
