These bioactives collectively are responsible for the ingredient's many valuable whole-body benefits. Guarana seed powder and extract have been used for centuries—and for good reason, too. The benefits of guarana span myriad areas of wellness. Below, discover some of the ingredient's most notable health effects:. When it comes to antioxidants , guarana doesn't disappoint. The Amazonian berry offers antioxidant compounds like theobromine, tannins, saponin, catechins, and caffeine, according to Paula Doebrich, MPH, RDN , registered dietitian and founder of Happea Nutrition. These antioxidants help the body fight off free radicals, Naidoo tells mbg, ultimately protecting cells, tissue, and organs from oxidative stress. If guarana had a claim to fame, this would be it. As Naidoo notes, "Guarana [promotes] energy due to its caffeine content, which is stimulating for both the body and mind. As you can imagine, this can be a lifesaver when you need to shake off physical and mental tiredness. The high content of antioxidants in guarana also lends a hand to these cognitive benefits, says Naidoo. These compounds help support brain health, which is key for optimal focus and mental clarity. According to Pasquariello, the caffeine in guarana nurtures cognitive function and performance, including important processes like memory, learning, processing, and attention. Case in point: According to a scientific review in the journal Global Psychiatry , caffeine is considered to be a nootropic—i. The same review found that guarana improved reaction time and accuracy of task performance in young, healthy adults, further bolstering this botanical's cognitive benefits. Moreover, in a Pharmacology Biochemistry and Behavior study, guarana was clinically shown to work synergistically 4 with Panax ginseng to promote cognitive performance. As a source of caffeine, guarana may also help promote digestive function, notes Doebrich. What's more, the tannins in guarana may support the formation of stool by regulating water secretion 6 in your GI tract, as indicated in a scientific review in the International Journal of Molecular Sciences. Over time, free radicals and oxidative stress can reduce skin elasticity and speed up signs of skin aging 7 , such as fine lines. However, consuming plenty of antioxidants can help protect skin tissue against these effects, especially as we get older. As sources of antioxidants, guarana tea and supplements can aid your skin by supporting your body's natural antioxidant defenses.
