The Guarana Study
Extensive research on guarana has shown amazing metabolic effects. One study showed an average of 15.6 pound weight loss in a group taking a mixture of yerba mate, guarana, and damiana, compared to an average one pound loss in a placebo group after 45 days.
The same study was later done with the Guarana Blast weight loss supplement and the results were staggering. The study showed an average of 24.3 pound weight loss in a group taking Guarana Blast, compared to an average one pound loss in a placebo group after just 45 days.
Obviously, guarana has amazing fat-burning properties that cannot be compared to anything else today. Brazilian tribes have been using guarana for quite some time and their life span was much higher than that of North Americans. It was discovered that an entire Brazilian tribe using guarana had an average life span of 90 years old and higher.
