Guarana is a climbing plant in the maple family, Sapindaceae, native to the Amazon basin and especially common in Brazil. Guarana features large leaves and clusters of flowers, and is best known for its fruit, which is about the size of a coffee berry. As a dietary supplement, guarana is an effective energy booster – it contains about twice the caffeine found in coffee beans (about 2-4.5% caffeine in guarana seeds compared to 1-2% for coffee beans). In the United States, guarana has the status of being generally recognized as safe (GRAS).
