Guarana – Paullinia cupana
This climbing plant of the maple family is native to the basin of the Amazon, especially in Brazil. Guarana seeds contain guaranine, which is similar to caffeine. The seeds have about twice the amount of caffeine as in coffee beans. It can be found in many weight loss formulas. As with other products that contain caffeine, be sure not to overdo it. Too much caffeine can make some people jittery and anxious.
Country of origin: Brazil
Safety: Avoid during pregnancy or if there is a sensitivity to caffeine or other central nervous system stimulants.
