Guarana is a climbing shrub in the maple family that grows wild in the Amazonion regions.
Most modern commercial Guarana is grown on government plantations where the highest quality plants are harvested and attempts to cultivate the planyt outside the Rainforest have not been successful.
As a dietary supplement, itis an effective stimulant as its seeds contain about twice the concentration of caffeine found in coffee seeds (about 2–4.5% caffeine in compared to 1–2% for coffee seeds).
The fruit is harvested when ripe, after turning a bright red or yellow. The gathered fruit yields a small round black seed which is crushed to form a paste containing a percentage of Guaranine (caffeine).
Besides caffeine, Guarana contains a host of other xanthines.; Theobromine and Theophylline are the primary xanthines, acting as muscle relaxants and possessing diuretic properties.
This product is standardised to 22% Caffeine.
