What is Guarana?


Guarana is a shrub or small tree in the Sapindaceae family, native to Venezuela and northern Brazil. Traditional uses of guarana by natives of the Amazonian rain forest include crushed seeds added to foods and beverages to increase alertness and reduce fatigue. As a dietary supplement, it's no wonder that guarana is an effective energy booster - as it contains about twice the caffeine found in coffee beans (about 3-4% caffeine in guarana seeds compared to 1-2% for coffee beans). Concentrated guarana extracts, however, can contain caffeine at levels of as much as 40-50%, with popular supplements delivering 50-200mg of caffeine per day (about the same amount found in 1-2 cups of strong coffee).

What is the effective dosage of Guarana supplementation?

The effective dosage of Guarana is 50 too 200 mg per day or follow the directions written on product labels.
