Guarana is obtained from dried and peeled seeds of the Paulinia Cupana plant. Originally it comes from the Amazon region. It was used there for a long time by the natives to suppress the feeling of hunger and against fatigue. This effect is due to the caffeine contained in these seeds. Unlike coffee, where caffeine is free, however, the caffeine in guarana is tied to tannins. Therefore, it is released more slowly and thus allows the great advantage – a longer lasting caffeine effect. In Guarana 1,800 shots we have used the best guarana quality for high caffeine levels and best taste. The liquid form allows a faster start than tablets or capsules, but without compromising the longer-lasting effect. With 1,800 mg of highly concentrated guarana extract, you get one of the highest dosing levels on the market. 180 mg caffeine with a longer-term effect corresponds to 2-3 cups of filter coffee.
