Guarana Seed Extract

Guarana is native to the Amazon basin and especially common in Brazil. As a dietary supplement, guarana is an effective stimulant[1] – it contains about twice the caffeine found in coffee beans.[2]

In rats, Guarana increased memory retention and physical endurance when compared with a placebo.[3] A 2007 human pilot study of Guarana extract found memory, alertness and mood were increased by the lower of four doses tested.[4]

In a study published in the journal Pharmacology Biochemical Behavior, a comparison of the absorption of caffeine from coffee, cola or capsules found the absorption from capsules was about 40% slower than that of coffee or colas.[5]

Caffeine is a central nervous system and metabolic stimulant,[6]and can result in increased wakefulness, faster and clearer flow of thought, increased focus.[7] The amount of caffeine necessary to produce effects varies from person to person, depending on body size and degree of tolerance. Effects begin less than an hour after consumption, and a moderate dose usually wears off in about five hours.[7]

Brazil produces several soft drink brands from Guarana Extract, sales of which exceed those of cola drinks.[8]

Each serving of Elebra contains caffeine from Guarana Seed Extract equal to a typical cup of coffee, and is manufactured in the USA at a cGMP facility that has an "A" rating (the highest possible) from the National Nutritional Foods Association.
