IMPROVES COGNITIVE FUNCTIONS:
The methylated xanthines present in guarana are stimulants of the central nervous system, with caffeine having the most powerful action.
Caffeine works by binding to adenosine receptors, increasing alertness in the individual, thus promoting an improvement in the association of ideas and intellectual activities, greater resistance to fatigue and a feeling of well-being (KUSKOSKI. Et al; 2015 ).
Its polyphenols have been related to a decrease in lipid peroxidation, and may help prevent the formation of atheroma plaques (Portella et al .; 2013) In addition, it has been suggested that the combination of caffeine and catechins has an activity that inhibits platelet aggregation. , being beneficial to decrease the risk of cardiovascular diseases (Subbiah and Yunker; 2008)

Most of the therapeutic properties of guarana, such as its antioxidant capacity, are attributed to high concentrations of phenolic compounds (tannins, among others), which have a retarding effect on cells. (KUSKOSKI. Et al; 2015)
It has been shown by Espinola et al., That after the intake of a dose of 0.3 mg / mL of guarana, a significant increase in the physical capacity of rats subjected to a stress situation is observed, in periods of 100 and 200 days of treatment. (KUSKOSKI. Et al; 2015)
An improvement in cancer-induced fatigue, both physical and mental, has also been described thanks to the consumption of guarana (Oliveira Campos et al. 2011)
Anti-inflammatory capacity in the presence of saponins, plant species with saponins and triterpenoids are known to be anti-inflammatory. It is also due to the presence of theophylline and theobromine that has these anti-inflammatory properties and its broncho-protective effect. (KUSKOSKI. Et al; 2015)
Tannins, especially the catechol type, confer useful astringent properties in cases of diarrheal states. (KUSKOSKI. Et al; 2015)
Aqueous extracts of guarana orally and parenterally have been shown to inhibit platelet aggregation (a part of the blood, clump together and cause blood clotting) and reduce thromboxane synthesis (which plays an important role in formation of the clot) both in vitro and in vivo. (KUSKOSKI. Et al; 2015).
HOW TO USE?

Guarana capsules (500mg)
Analysis was made in groups of animals treated with guarana with doses of 2000 mg / kg (vo) and 1000 and 2000 mg / kg (ip), which did not present significant differences compared to control groups in parameters such as urinary frequency, defecation, piloerection, motor activity, tremors, seizure, muscle tone, posture, loss of reflexes, lacrimation and salivation.
