It is deeply rooted in the mythology and culture of several indigenous South American groups. According to legend, the cultivation of this plant began after a deity killed one of the children from the village.

In an effort to console the people, the deity then plucked out the left eye of the child and planted it in the forest. This is where wild guarana is believed to have first originated.

Studies show that guarana can have a powerful impact on focus and memory. In fact, one study out of the Human Cognitive Neuroscience Unit at Northumbria University in the U.

showed that low doses were able to improve both memory performance and alertness compared to a control group. Similarly, another study conducted at Northumbria University compared the effects of guarana and ginseng and reported that guarana seed extract was able to significantly enhance task performance and attention to a greater extent than ginseng.

Guarana fruit contains a wide range of potent antioxidants, including caffeine, tannins, saponins, theobromine and catechins. Antioxidants are beneficial compounds that can help fight free radical formation and prevent oxidative damage to cells.

Not only that, but some research suggests that antioxidants can even protect against chronic conditions like heart disease, cancer and diabetes. Guarana is loaded with caffeine, with the seeds packing in a higher concentration of caffeine than even coffee beans.

Caffeine acts as a stimulant and affects the activity of certain neurotransmitters in your brain to amp up energy levels. This is why beverages like coffee and energy drinks are often used as a quick fix for low energy and fatigue. In addition to fighting physical fatigue, some research indicates that guarana can help reduce mental fatigue as well.

One study published in the journal Appetite showed that taking it was able to decrease mental fatigue associated with sustained mental effort in participants. Guarana has long been used as a natural remedy for both constipation and diarrhea.

It helps promote regularity and soothe digestive distress. Tannins are plant compounds that can prevent excess water from being excreted into the bowels to stop diarrhea fast. Research shows that the guarana seed benefits heart health in several different ways.

It can help prevent blood clots to reduce the risk of heart attacks and stroke, according to research out of the University of Cincinnati Medical Center.

Not only that, but it can also decrease the oxidation of LDL cholesterol in the blood. This can control the buildup of plaque in the arteries to prevent atherosclerosis. Guarana makes a great addition to any natural skin care routine thanks to its content of both caffeine and antioxidants.

Caffeine helps protect the skin against UV radiation. It also slows down photoaging of the skin and promotes circulation and blood flow. One study published in the Journal of Cosmetic Dermatology showed that cosmetics containing guarana helped reduce skin sagging and minimized wrinkles underneath and around the eyes.

Although current research is mostly limited to in vitro studies and animal models, preliminary evidence suggests that guarana could help effectively reduce the growth and spread of certain types of cancer cells.

For instance, one animal study showed that administering it to mice reduced liver cancer proliferation by 58 percent and increased cancer cell death by nearly fivefold. Other studies have had similar findings.

Results show it may help decrease the growth of colon and breast cancer cells as well. Guarana is often used as a weight loss aid.

In fact, there are many guarana weight loss products, pills and supplements to help ramp up fat-burning and shed extra pounds. This is partly due to its content of caffeine. Caffeine has been shown to boost metabolism by up to 11 percent over a hour period in research published in the American Journal of Clinical Nutrition.

Plus, several in vitro studies also show that guarana may slow and inhibit the production of fat cells to help decrease body fat. Guarana supplements are available in many different forms, ranging from guarana tea to guarana extract and beyond.

Guarana seed powder is also often added to beverages and products advertised to help naturally boost energy levels. Although there are no official guarana dosage guidelines available at present, most research shows that doses between 50—70 milligrams may be the most beneficial.

Stick to this dosage to maximize the potential health benefits and minimize the risk of adverse side effects. Low doses of guarana are generally safe and come with minimal risk of adverse side effects. In fact, multiple animal models have found that it has a low toxicity , even when consumed regularly.

Not only is caffeine highly addictive, but it can cause several negative effects on health. It can even contribute to a caffeine overdose when consumed in large amounts. 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.
