The burst open fruits of the guarana plant with their black seeds and white coating present a miraculous image in the wild: eyes staring at you. Numerous legends and myths of the indigenous peoples are linked to this phenomenon. Guarana is a highly caffeinated fruit that grows in the Amazon region of South America. With its 3.9% caffeine content, the South American jungle plant is a real powerhouse. This makes it the ideal energy supplier for people looking for a substitute to coffee. Since guarana is also free of irritants, it is significantly more tolerable than products made from the coffee bean. In addition, it releases its contained caffeine more slowly and evenly compared to coffee, which additionally increases the beneficial effect. Thus, the well-dosed use of guarana becomes a strengthening alternative to coffee or tea.
