Guarana and brain health -
If you notice these or any other side effects after consuming guarana, consider decreasing your dosage or discontinuing use altogether. Women who are pregnant should limit or avoid guarana-containing products. Increased caffeine consumption may be linked to a higher risk of birth defects and preterm delivery.
Additionally, guarana is often used as an additive for unhealthy beverages. These include guarana energy drinks or guarana alcohol products. Drinks that this are often pumped full of unhealthy added sugar and extra ingredients.
These products essentially negate any health benefits of guarana. They can actually do more harm than good when it comes to your health. There are many individual ingredients or products known for their ability to increase energy levels, boost fat-burning and fine-tune focus.
How do these ingredients compare? What sets them apart from one another? Taurine is a type of amino acid that is found in the tissues throughout the body. It can also be produced in small amounts. It is available in certain foods, including meat, dairy products and seafood.
It is believed to be associated with a number of health benefits, such as increased fat-burning during exercise and improved heart health. Adderall, on the other hand, is a type of prescription medication used to treat attention deficit hyperactivity disorder and narcolepsy.
When abused or taken in high doses for prolonged periods of time, it may also cause addiction and trigger withdrawal symptoms, similar to caffeine. Caffeine pills boast all the same benefits of caffeine, such as reduced constipation and increased energy levels.
However, they also come with the same set of side effects, which can include anxiety, restlessness and headaches. Coffee and green tea can be enjoyed as is, but guarana is typically found in supplement form or processed guarana drink products, such as guarana soda. In terms of caffeine content, guarana extract is significantly higher in caffeine than coffee.
Some studies indicate that the seeds contain four to six times as much caffeine than coffee beans. Green tea is the lowest in caffeine among the three. It has just 35 milligrams in a single eight-ounce serving. That is nearly one-third of the amount found in coffee.

Guarana is also found as an extract in some nootropic supplements 2 , like capsules and tablets. You'll want to look for the botanical genus and species Paullinia cupana on the label, along with the plant part i. As a botanical ingredient, guarana offers an impressive cocktail of native antioxidant compounds, including the unique phytonutrient caffeine.
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.
Additionally, a review from Skin Pharmacology and Physiology states the caffeine in guarana can enhance blood flow to the skin 8 , helping it look healthier and more youthful.
Due to the rich antioxidant content of guarana, the ingredient may have cardioprotective effects, according to a scientific review in Comprehensive Reviews in Food Science and Food Safety.
Specifically, the antioxidants in guarana have been found to protect lipid levels , which is crucial for maintaining cardiometabolic health. Interestingly, guarana might benefit the very body part it resembles. According to a compelling study 9 in the Journal of Functional Foods , the antioxidants in guarana can help nurture eye health and vision.
Needless to say, it's a guarana benefit you probably didn't see coming pun intended. Guarana supplements are available in several different dosage forms—with capsules being the most common.
Manufacturers in the United States make guarana products. To safely take natural products—like guarana—inform your healthcare providers and pharmacists about any medication changes. This includes over-the-counter OTC , herbal, natural medicines, and supplements.
Your healthcare provider can help prevent possible interactions and side effects. There are several sources of guarana, but nutrition guidelines typically favor food sources over supplements. Although food sources are preferable, there is still a place for supplements for people who have trouble absorbing nutrients, such as people in certain age groups or with certain medical conditions.
Guarana is naturally available as a native Amazonian Paullinia cupana P. cupana plant from the soapberry family called Sapindaceae. The U. Department of Agriculture USDA generally categorizes guarana or P. cupana as food. Guarana is made by shelling and washing the P.
cupana seeds. Afterward, the seeds are dried, roasted, and crushed grounded into a powder. This powder can be used to prepare tea.
It's also used as a flavoring agent. In fact, the FDA placed guarana on its approved list of substances added to food. Guarana is also commonly found in energy drinks. Guarana supplements are commonly available as capsules. Other supplement forms include:. Vegetarian and vegan options might also be available.
You may also see guarana in combination with other ingredients. Guarana is naturally available as a native Amazonian plant from the soapberry family. It may have potential antioxidant effects, brain health support, heart health support, and relief from the side effects of cancer or its treatments.
But like any medication or natural product, side effects and interactions are possible. And because no conclusions have been made regarding the efficacy and safety of guarana, it should not be taken in place of getting an accurate diagnosis and treatment for any symptoms or conditions you may have.
Before using guarana, involve a registered dietitian, pharmacist, or healthcare provider to help you safely achieve your health goals. Encyclopaedia Britannica.

Severe allergic reaction : Avoid guarana if you have a known allergy to it or other ingredients or parts of the supplement. If you need clarification on whether it's safe, ask a registered dietitian, pharmacist, or healthcare provider for more information.
Pregnancy : Guarana is a plant with a high caffeine content. Generally, caffeine may raise your heart rate, blood pressure, and the amount of urine you make. Other potential effects are tremors, indigestionlight-headedness, nauseaand sleeping problems. While pregnantyou might be more sensitive to these effects.
As for the impact on the unborn fetus, there is conflicting information about caffeine's effects on miscarriagespreterm birthsand low birth weights.
But adverse effects are unlikely with daily caffeine amounts of milligrams mg or less than one to two cups of coffee daily.
Since additional research on guarana is needed, contact a healthcare provider to discuss the benefits and risks before using guarana during pregnancy. Breastfeeding : Guarana is a source of caffeine. For this reason, guarana will likely have similar effects as caffeine on nursing infants. For example, 10 cups of coffee per day from a breastfeeding parent might be too much for a nursing infant.
The breastfeeding infant may experience fussiness, tremors, and sleeping problems at these high amounts of caffeine. And more than milliliters mL of coffee per day can reduce iron levels in breast milk, increasing the chances of low iron levels and anemia in nursing infants.
In general, try to limit the amount of coffee to a maximum of to mg, or five cups of coffee per day. These amounts are likely safe for babies at least 3 weeks old. But preterm and newborn infants tend to clear out caffeine slower. Therefore, be sure to use guarana with caution.
Before you use guarana, contact a healthcare provider to discuss the benefits and risks. Adults over age 65 : Older adults participated in some guarana-related studies.
In general, however, more rigorous research on guarana is still needed. Moreover, older adults are generally more likely to have medication side effects than younger people.
For this reason, people in this population should use caution with guarana. Children : Children may get caffeine from various sources, such as plant-based foods and drinks—like guarana.
According to a systematic review a methodical review of a collection of studiescaffeine may have positive and negative effects on children. Positive ones may include supporting brain function and athletic performance.

Animals : There are reports of poisoning in dogs from herbal products that contain guarana. Symptoms may include:. Before using guarana in animals, you can contact a veterinarian to talk about the benefits and risks.
Heart conditions : High doses of guarana may be similar to caffeine overdose symptoms, such as abnormal heart rhythm and rate. Therefore, a healthcare provider may want to monitor you and make any necessary medication adjustments closely. Liver problems : Guarana has some similar plant substances as green tea.
And these substances might have a role in liver toxicity associated with green tea use. While there are no reports of liver injury with guarana, long-term guarana use at high doses isn't recommended in people with liver problems.
Seizures : Guarana may work against anti-seizure medications and increase your risk of seizures. A healthcare provider may want to monitor you closely and make any necessary medication adjustments if you have seizures. Always speak with a healthcare provider before taking a supplement to ensure that the supplement and dosage are appropriate for your individual needs.
While some studies on guarana in humans exist, more research with high-quality clinical trials is still necessary.
For this reason, there are no guidelines on the appropriate dosage to use of guarana for any condition. The specific dose may vary based on the dosage form and any medical conditions you may have. If you use guarana, follow a healthcare provider's recommendations or product label instructions.
More information about the safety, toxicity, and overdose of guarana in humans is needed. However, guarana toxicity likely resembles that of a caffeine overdose.
Signs of a potential overdose include:. Per a systematic review, side effects might be less of an issue with maximum daily guarana doses of between and 1, mg.
But in another review, clinical trials studied daily guarana doses of 3, mg. If you suspect you're experiencing life-threatening side effects, seek immediate medical attention.

Guarana is a small, round berry that's native to Brazil, according to Uma Naidoo, M. For thousands of years, it's been used by Indigenous communities in the Amazon 1 for its naturally stimulating effects. It consists of a red outer skin and white pulp that, when ripe, breaks open to expose a black seed. In turn, it resembles a human eye. The seed, however, is the real star of the show. According to a scientific review in the Comprehensive Reviews in Food Science and Food Safety , the seeds are separated from the skin and pulp—then fermented, roasted, and ground into a powder. Traditionally, this powder is consumed in tea or mixed into beverages, says Naidoo. Guarana is also found as an extract in some nootropic supplements 2 , like capsules and tablets.

A Paulínia cupana o guaraná é uma planta da flora brasileira que goza de grande prestígio na medicina popular, entre eles de ser potente estimulante das funções cerebrais. Os autores avaliaram os efeitos da administração crônica da guaraná sobre a cognição de voluntários idosos normais. Foram estudados 45 voluntários, sendo distribuídos aleatoriamente para um dos três grupos experimentais. Não obteve-se nenhuma mudança significativa na cognição desses voluntários. The effects of long-term administration of guarana on the cognition of normal, elderly volunteers. Brazilian Information Center on Psychotropic Drugs of the Department of Psychobiology at the Federal University of São Paulo - São Paulo, Brazil. Address for correspondence Address for correspondence: José Carlos Fernandes Galduróz Escola Paulista de Medicina - Depto. Psicobiologia Rua Botucatu, - 1º andar - V. The concept of adaptive or resistant drugs has arisen in the past years thanks to extensive research done by Soviet, Japanese and Korean scientists on several plants, especially those from the Araliaceae family. Although folkloric use of these plants has always spurred curiosity, there have been, in general, few scientific studies on these plants. In fact, it has been difficult to observe any immediate effect of these plants in relation to all the alleged therapeutic effects that have been reported by popular medicine 11, It was only possible to verify their typical effects and isolate their active ingredients 2 when investigations stopped searching for short-term effects in normal animals, and demonstrated the plants' protection against aggressive agents through long-term use. Of ten adaptive plants studied in the former Soviet Union, five have already been officially approved for therapeutic use 2 : Panax ginseng, Aralia elata, Aralia cordata, Acanthopanax senticocus used for astronaut preparation and Oplopanax elatus. In Brazil, our scientific community has devoted little effort to investigating our vast flora for adaptive plants. Therefore, it is not possible to find scientific studies relevant to this matter. However, in Brazilian popular medicine, several plants are used with the same purpose as other folk medicine found in China and other countries. Guarana Paulinia cupana and the Pfaffia paniculata are good examples. Guarana is attributed with powerful preventive and curative actions all without scientific proof and, among these, we can cite some of its indications: neuralgia, migraine, arteriosclerosis, menstrual pain, weight loss, renal activation, bad digestion, heart and brain stimulation, and others Anthropologist A. HENMAN, in his study of guarana 16 , describes the use of this plant by the Satere-Maue Indians who live in the Amazon, emphasizing its use as a liquid preparation which is diluted and taken several times during the day on a long-term basis. He also reports that guarana has been used by these Indians for centuries as a stimulant, headache medicine, and for relief of cramps, etc. In relation to its botanical classification, PIO CORREA 21 as well as HENMAN 16 , describe guarana as being from the Sapiendaceae family, with two subspecies: Paulinia cupana var sorbilis and Paulinia cupana var typica. Chemically guarana is characterized by its high-grade caffeine, with a smaller quantity of theophylline and theobomine. It is known that these substances do not have pharmacological actions that can explain all the therapeutic effects popularly attributed to guarana. In fact, the central stimulating effect of caffeine cannot explain the majority of them 3. On the other hand, a presence of a high concentration of tannin in guarana has been described as percent, according to HENMAN The following study considers the effect of the long-term use of guarana on the cognition of normal, elderly volunteers. The project was approved by the Ethics Committee of the Federal University of São Paulo in Anima Nobili. All volunteers signed a Term of Agreement to participate. GROUP II - CAFFEINE, in quantities equivalent to doses of administered guarana. The purpose of this group was to assess the different cognitive effects of guarana and caffeine, if any. The sample of guarana used was analyzed by EMBRAPA Brazilian Agropecuarian Research Company and had the following components:. The volunteers in each experimental group took two capsules a day one in the morning, one in the afternoon for days of the study. Each capsule contained mg of powdered guarana; the capsules of caffeine contained The doses of 1 gram of guarana per day was decided upon after studying the recommendations of laboratories that sold the product, and a previous study done by this department All capsules were identical since this was a double-blind study, and volunteers were randomly divided into one of the three experimental groups. The Mini-Mental State 10 was used as screening for dementia with a cut-off score of 23 points. Among neuropsychological assays, we used Digital Span 24 to assess immediate memory; Free Recall for recent memory 1 ; Digital Symbol to evaluate psychomotor activity and concentration 8,14 ; Cancellation tests to verify vigilance and attention 7 ; and, finally, the Mosaic test for visual and spacial organization The Raven - Progressive Matrices Advanced Scale was used. It is indicated to assess general abilities, having shown sensitivity to detect reasoning and visual perception damage 5. Each volunteer was submitted to a clinical evaluation physical and laboratory exams followed by the Mini-Mental State exam and neuropsychological tests to determine the basal cognitive state. We also applied the Sleep Scale and the Anxiety Inventory. The selected volunteers initiated the intake of one of the three substances with initial clinical follow-up every week, and then every month to receive more capsules, thus providing not only the necessary clinical care, but also assuring us that the substances were being used regularly. In the third and fifth month after beginning treatment, the complete evaluation of the basis phase was again repeated Fig. Data was analysed using non-parametria tests. For the analysis of dependent samples, we used the Friedman test and, for independent samples, we used the Kruskal Wallis test. The significance level was 5 percent. The study was developed at the Center of Clinical Research of the Department of Psychobiology at the Federal University of São Paulo from January to September These are the following social and demographic characteristics of the 45 subjects: mean age was 65 60, 76 ; 20 were male 44 percent ; 39 married, 5 bachelors, and 1 widower; 25 volunteers had finished high school, 15 had finished primary school and 5 had graduated from university. Table 1 shows the results of two cognitive tests used for memory assessment. There were no significant differences. Table 2 shows that the volunteers presented an improvement in the Digit Symbol test when the final and initial assessment were compared, although there were no differences between the three groups Placebo, Caffeine and Guarana. In the results of the Mosaic test, the guarana group showed significant improvement, but it is important to note that the initial results of this group were already higher in comparison to the other two groups, although not significantly. Finally, Table 3 shows data in relation to the volunteers' levels of anxiety measured by the Anxiety Inventory and the detection of affected reasoning Progressive Matrices - Raven. There were no significant alterations. |
