Guaraná {Paullina cupana} 500mg Click on product name for Information Page. Un-Roasted, Sun-Dried Stone-Ground 100% pure un-roasted sun-dried stone-ground Guaraná seed in Vegetarian-caps. Guaraná is the energy food of the Tupæ & Tamoyo Indians of the Amazon rain forest of Brazil. Amino Acid & Botanical Supply™ may be the only brand of un-roasted sun-dried Guaraná available in the U.S. Most Guaraná in the U.S. market is roasted. Roasting converts the active ingredient of Guaraná – the alkaloid Guaranine, a much gentler and longer acting stimulant into Caffeine which when concentrated is a much harsher stimulant with a following depression. Or as the Tupæ say “roasting Guaraná will anger the gods.” Yes my friends, now we all can aspire to the Protestant {or Tupæ Indian} Work Ethic without getting depressed or incurring the fury of the gods!
