So why do some people still believe that guarana causes high blood pressure? It may be due to a misunderstanding of correlation and causation. While it is true that some people who consume guarana may have high blood pressure, it is not necessarily the result of consuming guarana.

One of these bacteria is Escherichia coli E. coli , which lives in the intestines of humans and animals. Most E. coli bacteria are harmless, but some can cause diarrhea or illness 38 , Studies have also found that guarana can suppress the growth of Streptococcus mutans S.

Phosphatidylcholine is known to boost cognition, but its potential benefits don't stop there. However, the success of production, exporting and consumption of guarana can be explained in one word: caffeine.

You see there is a reason why in Brazil one of the popular names for this supplement is "Zoom" The seeds from which the extract is taken consist of between 2. Whilst there is some variety in caffeine content, to put it in perspective, the average concentration would be greater than both tea and coffee In fact the amount of caffeine in guarana is twice the amount found in Arabica coffee beans 1.

These levels of high caffeine potency lend guarana it's significant stimulant effects. Such a high concentration of caffeine modifies hormonal action norepinephrine and epinephrine release and inhibits central adenosine receptors.

Thus, leading to gross central nervous system excitation. Energy drinks come in all concoctions and forms, some of which get a boost from added guarana.

It is well established that the success and efficiency of energy drinks comes most predominantly from their caffeine content , which of course can be supplied by this supplement. Energy drinks containing caffeine show various benefits for performance including delaying training fatigue 18 ; enhancing muscle strength 18 and increasing muscle endurance There is also evidence that caffeine positively stimulates our resting energy expenditure, meaning we burn more calories at rest This augmentation of metabolism is caused by stimulation of a cycle which boosts levels of adrenalin 21, This is an amount of caffeine easily supplied by guarana making it a perfect constituent of energy drink beverages which are sold on the premise of being ergogenic aids.

One study examined the effect of guarana consumption over a period of 14 days on rats, and measured the effect on lipid metabolism This study showed a reduction in plasma lactate concentration in exercising rats, as well as increased muscle glycogen content.

These results would therefore indicate changes in lipid metabolism during exercise and muscle glycogen sparing; changes which these authors explain are dependent on the degree of caffeine in the particular guarana supplement. However, secondary results of this study outline other potential theoretical weight loss mechanisms.

Firstly, food intake was decreased in a higher dose group of guarana, indicating a potential effect on satiety in the test animals. Their results also show that the animals had a reduced content of bodily fat post experiment, which the authors explain is likely due to both caffeine content and theophylline content, which is a potent adenosine receptor antagonist and which has been associated with fat breakdown However, most intriguingly the final weight gain of the animals fed and exercised in the study was lower in a group who were given a decaffeinated guarana extract, which suggests a mechanism beyond the caffeine-induced changes in lipid metabolism.

The authors suggest that the content of other biological compounds tannins and catechine also contribute to body weight changes following guarana supplementation. The question remains whether these changes to fat metabolism, body fat content and weight gain actually transfer to us humans if we take a guarana supplement?

A randomised controlled trial of a guarana supplement consumed by 67 overweight adults for 8 weeks aimed to shed light on this question This study gave half of the subjects an herbal weight supplement containing 40mg guarana, alongside a secondary component of 12mg Ma Huang a preparation from the Chinese plant ephedra sinica ; and the other half they gave a placebo supplement.
