Reduce Fatigue and Improve Focus

The most well-known use for guarana is as a component of popular energy drinks. It's a great source of caffeine, which keeps your attention and energy levels high. Actually, guarana seeds might have four to six times the amount of caffeine in them than coffee beans.

The way caffeine works are by counteracting the effects of adenosine, a substance that promotes mental relaxation. Adenosine receptors are bound by it, which stops them from being triggered. According to research, participants who took a vitamin supplement containing guarana had less exhaustion while undergoing a battery of tests than those who took a placebo. Surprisingly, research demonstrates that guarana can lessen cancer treatment-related mental weariness without having a major negative impact.
