what is l guarana caffeine
Guarana (Paullinia cupana) is a sacred plant that originated in the Amazonian forest and was used for more than 3,000 years by the Indians. Guarana has become very well known as a highly effective tonic plant, thanks in no small part to the fact that it contains 4-5 times more caffeine (guaranine) than coffee itself.uarana is a plant that is used by many people, particularly in Brazil, but as is the case with coffee, which is used by millions of people throughout the world, this is not to say that it is necessarily good for general health.
