Why Should You Have Guarana?
1. Helps In Appetite Suppression
Guarana is rich in bioactive compounds like caffeine, theobromine, theophylline, tannins, saponins, catechins, epicatechins, and proanthocyanidins. When teamed with yerba mate and damiana, guarana managed to suppress appetite in obese women. In other words, their hunger pangs and desire to eat reduced, leading to weight loss (1). Guarana has also been found to control the expression of genes that are involved in fat accumulation. It downregulates the expression of pro-adipogenic genes while promoting the expression of anti-adipogenic genes (2). Anecdotal evidence suggests that this fruit may also boost metabolism due to its caffeine content, which can aid weight management. Hence, it can be used to stimulate healthy weight loss in obese individuals and treat eating disorders.
2. Stimulant And Energy Boosting Effect
Along with caffeine, guarana has tannins, alkaloids, catechins, and epicatechins. This is why it has many stimulant mechanisms. It mobilizes calcium, helps in the binding of caffeine to its receptors in the CNS, triggers the production of ATP (energy), and ultimately improves cognitive performance, concentration, and alertness. Research says that it is the cumulative effect of caffeine along with other active components that make guarana an effective stimulant for vitality. Guarana has no significant effects on long-term psychological well-being, anxiety, and mood (3), (4). Therefore, it is used in many energy drinks and dietary supplements to increase endurance for workouts and daily tasks.
3. Manages Anxiety And Neurodegenerative Disorders
Guarana powder can have protective effects on your brain and nervous system. It prevents amyloid plaque formation (or accumulation) and protein glycation, reduces oxidative stress, eliminates reactive oxygen species (ROS or free radicals), and decreases acetylcholinesterase activity. All these effects prevent neuronal death, thus proving beneficial for treating cognitive disorders like Alzheimer’s, Parkinson’s, and Huntington’s diseases in model organisms. Thanks to its interesting phytochemical composition, guarana improves memory and lifespan of organisms suffering from anxiety despite having a high caffeine content (5). Thus, it may be a beneficial ingredient to improve brain function.
4. Antibacterial Properties
Tannins make up a significant fraction of the bioactive ingredients in guarana. Along with other phytochemicals, tannins pose a threat to several notorious bacterial strains, such as MRSA (methicillin-resistant Staphylococcus aureus), Streptococcus mutans, and Streptococcus sobrinus. Guarana also reduces the levels of pro-inflammatory compounds (viz. interferons and interleukins) in your body. This indirectly shows that it can be a potent anti-inflammatory agent and protect you from bacteria-induced hypersensitivity (6).
5. Might Improve Quality Of Life In Cancer Patients
Due to the antioxidant and anti-inflammatory effects of guarana, it can be used as an inexpensive and non-toxic alternative for treating fatigue, anxiety, anorexia, and other chemotherapy-induced disturbances. Cancer patients undergoing chemotherapy and radiation therapy showed improvement in their behavior, appetite, body weight, and quality of life when given various forms of guarana extract. Alcoholic extracts of guarana have free radical-scavenging, antimicrobial, antiproliferativei It refers to the property of a substance to inhibit the spread of malignant cells into the surrounding tissues. , and antineoplastici It refers to the property of a medicine or substance to prevent the growth and spread of cancer cells. properties. Hence, along with treating the side effects, guarana could also help in limiting the growth and spread of certain cancers. However, there is scope for further in-depth research in this dimension (7), (8), (9).
6. Cleanses Skin And Scalp
The seeds of guarana have potent antioxidant and antimicrobial properties as they contain high amounts of methylxanthines (caffeine, theobromine, and theophylline), saponins, pigments, and choline. Guarana is used in skin and hair products due to these properties. Guarana can give you young and glowing skin, shiny hair that is free of dandruff, and also cure most of the pathogenic infections on your skin and scalp. Some products used to treat cellulitis have also incorporated guarana and its various parts because of its high caffeine content (10).
7. May Aid Digestion
8. May Improve Respiratory Health
Guarana’s high caffeine content may provide beneficial effects for overall respiratory health. Caffeine has anti-inflammatory and bronchoprotective properties, giving it the reputation of an effective ventilatory stimulant (12). It is also used to help relax breathing during exercise in highly trained athletes. What is it in guarana that gives it the benefits mentioned above? Read the next section to find out.

Apart from caffeine, guarana has many phytochemicals in its leaves, fruits, and seeds. The seeds of guarana contain methylxanthines, saponins, starch, polysaccharidesi Naturally occurring plant carbohydrates present in plant cells, and acts as a crucial source of energy for animal cells. , pigments, fats, acylglycerols, cyanolipids, and choline. Its beans contain catechutannic acid, catechic acid, starch, protein, oils, calcium, phosphorus, and tannins, along with caffeine. So, it’s not just caffeine that’s responsible for its stimulant effect. There is little to no information about the macro- and micronutrients present in guarana. So, until we find out more about its nutrient profile, let’s just eat guarana for its loaded phytochemical profile.
Do You Get Guarana Everywhere? In What Forms Is It Available?
Importing guarana is an expensive affair. Climate also plays an important factor in keeping the fruits viable. A relatively cheaper and more practical way is to use its supplements. The recommended dosage for guarana is about 200 mg to 800 mg (or 2-3 mg/kg). Long-term dosage is not recommended because it contains high levels of caffeine and other methylxanthines (13).
