The Guarana Animal Study
A study was conducted on the effects of guarana on the metabolism and its fat-burning properties. The research was conducted on mice and rats during a 14 day period. The study showed a significant fat-cell reduction in the mice and rats that participated, when given a chronic guarana dose over 14 days.
The study also showed that the fat-burning properties of the guarana plant was due to its caffeine content. When given the non-caffeinated version over the same period of time to the mice and rats, the guarana extracts had no effect on lipid metabolism.
The rats and mice were not harmed during this study, but on the contrary, they seemed more energetic, more alert, and their metabolism rate improved as well.
