Guarana Seed Powder Extract 10% Caffeine

Guaraná, from the Portuguese, Paullinia cupana, is a climbing plant in the family Sapindaceae, native to the Amazon basin and especially common in Brazil. Guaraná has large leaves and clusters of flowers and is best known for the seeds from its fruit, which are about the size of a coffee bean.As a dietary supplement or herb, guaraná seed is an effective stimulant: it contains about twice the concentration of caffeine found in coffee beans (about 2–8% caffeine in guarana seeds, compared to about 1–3% for coffee beans). The additive has gained notoriety for being used in energy drinks. As with other plants producing caffeine, the high concentration of caffeine is a defensive toxin that repels herbivores from the berry and its seeds.
