Guarana is one of the most known fruits of Brazilian flora, mainly when associated to beverage industry. But its nutritional richness makes it much more versatile. In addition to the use as a basis for beverage, it is also used in food supplements, phytotherapic drugs and even in cosmetics industry. Original from Brazilian tropical forests and domesticated by Indians, it has always been valued by its energy power, due to high presence of caffeine (amount of 4 to 8% more than in a coffee grain).
But the fruit can also be associated to an increased concentration and mental alertness status, fatigue combat, physical resistance growth, and also, can be used as an appetite suppressant and fat burn. Psychopharmacological tests found that guarana can improve memory and humor.
