Guarana is a shrub found in Brazil and mostly in Amazon rain forest. It bears small red fruits that contain black seeds. The seeds after washing and drying are powdered and brewed in to tea by the locals. It is said that they could stay without food for two days while hunting in the wild after consuming guarana. The appetite suppressant effect is related to the caffeine content in the seed. These seeds are so rich in caffeine that they contain three times more caffeine than that of a coffee bean.

Guarana has been used in traditional medicine in Brazil and surrounding areas as they contained certain tannins and alkaloids. Subsequently research had been done on this shrub and many of its health benefits revealed.

Now it is commercially sold in the form of pills, extracts, powders. Popular energy drinks such as Red bull, Rock star, monster etc. also contain guarana. It is used as nutritional supplement to athletes looking for peak performance. It produced the greatest alertness and improvement in the performance of mental tasks.

If you miss a dose use the next dose, but do not use extra guarana to make up the missed dose. It is advised to avoid using stimulant drugs while using Guarana.
