May Relieve Chronic Diarrhea and Treat Constipation

Since ancient times, guarana has been utilized as a natural stomach tonic to treat digestive issues like constipation and persistent diarrhea. Due to its high concentration of tannins, which are plant-based antioxidants, it could offer anti-diarrhea qualities. Because of its astringency, or ability to bind and constrict tissue, tannins are well recognized. This enables tannins to limit the amount of water released into your bowels by waterproofing the walls of your digestive system.

On the other side, guarana contains a lot of caffeine, which has the potential to have laxative effects. The peristalsis mechanism, which is stimulated by caffeine, causes the muscles in your colon and intestines to contract. Forcing the contents to the rectum may help with constipation. Guarana dosages that are low in caffeine are more likely to have an anti-diarrheal effect. Increased caffeine intake may have laxative effects.
