Guarana is a creeping shrub native to the Amazon.  The fruit is small, round, bright-red in color, and grows in clusters. As it ripens, the fruit splits and a black seed emerges.  This seed is the active part.  It is dried and then roasted just like a coffee bean.  The roasted seeds are ground and mixed with water to form a paste.  This paste retains all the active phytochemicals and is what is used in the production of Eiro Energy.  Now, let’s look at how Guarana affects your body.

There are 4 Xanthines in Guarana: Caffeine, Paraxanthine, Theobromine, and Theophylline.  Each, working synergistically, contribute to the pharmacological effects of Guarana.  In clinical studies, the xanthine alkaloids in Guarana have been shown to stimulate and strengthen the heart, stimulate the central nervous system, enhance alertness and alleviate fatigue.(1) * Clinical evidence suggests that Guarana inhibits platelet aggregation (sticky blood) and helps prevent the formation of blood clots.(2) * Recently, Guarana was validated by scientist as effective in improving mental acuity and enhancing long-term memory and memory retention.(3) *  The xanthines in Guarana have been found to facilitate weight loss, by creating a feeling of fullness and increasing thermogenesis (fat burning).  Caffeine increases resting energy expenditure and causes an increase in turnover of fatty acids, thus promoting “fat burning” within the cells.(4) * For improving athletic performance, caffeine has been shown to decrease perceived levels of exertion, which enables the athlete to feel less tired.  It also seems to enhance muscle metabolism and improve oxygen utilization.(5) *

To sum it up, Guarana has been used worldwide as an energy tonic and natural stimulant.  In addition, it has many health promoting benefits and is accepted as a safe way to boost energy.  Another way that Eiro Energy gives your mind and body a balanced boost.
