Best pain killer for medical operations. Had bone graft, sinus lift, molar extraction and 4 dental implants with only slight discomfort during and every day for a month while healing.

The euphoria during the operation was crazy good. I had several injections at each of the work sites to avoid any pain during surgery and Guarana with chamomile tea to make the whole experience heavenly. No Nsaid ever did that for me. I was expecting a fair crash a few hours after taking two pills one around am and the other 12pm but no crash just sustained energy throughout the day, i did consume an two L-Theanine tabs when in the morning so that maybe balanced things out but no anxiety unlike a caffeine pill may deliver and a ahhh life is great high throughout the day!

good product. And it works! The first time I took it, it was a more anxious, negative energy, but one I still felt I needed to work off at the gym. Which was the point for me.

But the more I take it, the more it feels better. It does upset my stomach a bit, but it passes. The energy I get from this supplement lasts all day. I only take it on the days I go to the gym. I will definitely be buying it again.

But severe side effects! I was using the powder form since a while, decided to give this product a try, to save some money.

It works, but not as expected. 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.

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. Market : Global USA.

Guarana has been historically marketed as part of diet pills, and researchers are evaluating its usefulness in controlling body weight. Researchers concluded that guarana was able to prevent weight gain despite the mice having identical diets.

In another study of overweight women, guarana showed the ability to regulate gastrointestinal hormones and reduce macronutrient intake.

According to some studies, guarana extract shows promising antidepressive effects in humans. Guarana consumption has been associated with lower rates of cardiovascular metabolic diseases.

It also may have positive effects on metabolizing lipids. Guarana was found to act similarly to other caffeine and catechin rich foods like green tea, where guarana fights the accumulation of LDL, preventing cardiovascular disease.

Some research even points to guarana being useful in the treatment and defense against certain neurodegenerative disorders. The exact mechanism behind this behavior still eludes scientists but they believe that guarana has the potential to prevent the death of certain neurons, which would make it useful in combating age-related diseases.

Another study used flatworms to investigate possible uses for guarana regarding longer life. The study concluded that the guarana extract extended the lifespan of the flatworms by possibly speeding the metabolization of fats. The guarana plant has evolved certain features including high caffeine content and saponins over thousands of years that help defend against microbial infections caused by various microorganisms.

These defense mechanisms could be useful in preventing diseases in humans as well. This study found that the guarana extract in mouthwash has been effective in preventing cavities, plaque build up, and other periodontal diseases. Brazilians have claimed for hundreds of years that guarana has a strong aphrodisiac effect.

Some indiginous tribes have gone so far as to say that the seed helped them to establish dominance, not only militarily but also sexually. One study used rabbits to evaluate this claim and found that there was a positive correlation between guarana consumption and rabbit mating.

Another study using Mediterranian fruit flies found that guarana increased the success of fruit fly mating.

While guarana contains more caffeine than any other plant in the world by dry weight up to four times as much caffeine as coffee , caffeine does not account for the plethora of other reported benefits. Caffeine is the first of three naturally occurring chemicals called methylxanthines.

The effects of caffeine set in between 5 to 30 minutes after consumption. Caffeine acts as a central nervous system stimulant; it increases blood pressure for a short time and heart rate.

Users report feeling more alert, active, and less fatigued. Theobromine is the second xanthine found in guarana and is a bitter tasting alkaloid abundant in dark chocolate. It is a vasodilator opens blood vessels , a diuretic, and heart stimulant.

It acts similarly to caffeine, and may help manage fatigue and orthostatic hypotension. There is also research that suggests theobromine can boost your mood.

This same study demonstrates that theobromine exhibits anti-tumoral and anti-inflammatory properties with regards to the cardiovascular system Theobromine has also been used as a smooth muscle relaxant. The third of the three methylxanthines naturally found in guarana, theophylline stimulates the heart and central nervous system.

Synthetic forms of theophylline have been used to treat airway diseases for more than 70 years. Both natural and synthetic forms of theophylline are bronchodilators, relaxing muscles around the airways. Theophylline has also been shown to have an anti-inflammatory effect in asthma and COPD.

Responsible for the bitter taste of guarana, tannins occur naturally in the roots, barks, and fruits of many plants. Due to its astringent and binding properties, tannins have been used to treat tonsillitis, pharyngitis, hemorrhoids, and open wounds.

There are two types of tannins: hydrolyzable tannins and condensed tannins. Condensed tannins are found in plants and can strongly affect the taste and mouthfeel of food. This may relieve constipation by pushing contents to the rectum Low doses of guarana do not provide much caffeine, so they are more likely to have an anti-diarrhea effect.

High doses provide more caffeine and may have laxative effects. The tannins in guarana may relieve diarrhea by preventing water loss. Meanwhile, the caffeine in guarana may relieve constipation by stimulating contractions in your intestines and colon that push contents toward the rectum.

Heart disease is responsible for one in four deaths in America First, the antioxidants in guarana appear to aid blood flow and may prevent blood clots Oxidized LDL cholesterol can contribute to plaque build-up in your arteries. However, most research on the connection between heart health and guarana comes from test-tube studies.

More human-based studies are needed before recommendations can be made. Guarana may aid heart health by improving blood flow and preventing blood clots. Two of these receptors — A1 and A2a — are involved in stimulating feelings of pain This is one reason why caffeine is commonly found in many over-the-counter pain relief medications.

Studies have shown it can significantly enhance their effects The caffeine in guarana may provide pain relief by blocking adenosine receptors, which are involved in stimulating feelings of pain. Due to its strong antioxidant and antimicrobial properties, guarana is popular in the cosmetics industry as an ingredient in anti-aging creams, lotions, soaps and hair products.

Moreover, its caffeine content aids blood flow to the skin Test-tube studies have shown that the antioxidants in guarana may significantly reduce age-related skin damage 9. Guarana has antioxidant and antimicrobial properties, making it a common additive in cosmetic products.

It may aid blood flow to your skin, reduce damage linked to aging and minimize undesirable features, such as saggy skin and wrinkles. Animal and test-tube studies suggest that guarana may protect against DNA damage, suppress cancer cell growth and even trigger cancer cell death 34 , 35 , Another test-tube study found that guarana suppressed the growth of cancer cells in the colon, as well as stimulated their death Scientists believe that the potential anti-cancer properties of guarana stem from its content of xanthines, which are compounds that are similar to caffeine and theobromine.

That said, though the results of test-tube and animal studies are promising, more human-based research is needed.

Animal and test-tube studies have found that guarana may have anti-cancer properties. However, human-based research is required before recommending guarana for treatment. One of these bacteria is Escherichia coli E. coli , which lives in the intestines of humans and animals.

Most E. coli bacteria are harmless, but some can cause diarrhea or illness 38 , Studies have also found that guarana can suppress the growth of Streptococcus mutans S.

mutans , a bacteria that can cause dental plaques and tooth decay 40 , Guarana contains compounds that may inhibit or kill harmful bacteria, such as E. coli and Streptococcus mutans. Things like sunlight, poor diet and certain lifestyle choices like smoking can wear down your eyes over time and increase your risk of eye-related disorders Guarana contains compounds that fight oxidative stress, a major risk factor for age-related eye disorders like macular degeneration, cataracts and glaucoma One study found that people who consumed guarana regularly had better self-reported vision than people who consumed it sparingly or not at all In the same study, scientists performed test-tube experiments to discover if guarana could protect eye cells against compounds that create oxidative stress.

Guarana significantly reduced the amount of DNA damage and eye cell death, compared to a placebo That said, there is limited research in the area of guarana and age-related eye disorders.

Test-tube studies have found that guarana may combat oxidative stress, which is linked to age-related eye disorders. However, this area of research is limited, so more human-based studies are needed before providing recommendations.

Research shows that guarana has low toxicity in low-to-moderate doses 19 , 46 , In high doses, guarana may cause side effects similar to those of excessive caffeine intake , including 48 , 49 :.

Pregnant women should avoid or limit guarana intake, as caffeine can cross the placenta. Guarana, in addition to caffeine, contains antioxidants, which together give it properties that support the body physically and mentally.

How does guarana work and what can it help? You can see guarana in the ingredients list of almost every energy supplement or energy drink. It is also added to preparations for sharpening mental abilities and supporting weight loss.

What does it have so that it is used in this way and what exactly is guarana? Guarana is a tropical plant that originates from the Amazon Rainforest. It grows as a climbing shrub with woody lianas. It was originally cultivated by the native people of the Sateré-Mawé tribe in Paraguay.

The botanical name for guarana, which is very different from the regular one, is Paullinia cupana. It is derived from the name of the first botanist who classified it.

Guarana belongs to the same family as lychee and longan "dragon's eye". All these fruits have in common the fact that they all look like an eye - the dark seed is surrounded by a white pulp enclosed in a peel, which deceptively resembles an eyelid.

Going back to the root of the name "guarana", it can be translated as "fruit with the appearance of a human eye". The peel of the guarana fruit can range in colour from orange to dark red.

The fruit is gathered in dense, long clusters resembling grapes. However, the properties of guarana are hidden not in the fruit, but in the seeds themselves, which are very rich in caffeine.

Guarana seeds contain 4 to 6 times more caffeine than coffee beans. Due to its caffeine content and other active ingredients, guarana can display the following effects:. Guarana is a very popular ingredient in energy drinks, whose role is to support the body during work and study as well as in cases of sleep deficiencies.

Guarana is most commonly available as guarana powder - dried and ground guarana seeds - or as guarana seed extract. Which is better? Guarana in powder or extract form?

Guarana extract is more reliable and easier to take because it is standardised for caffeine content. It means that, when you take a guarana extract tablet, you know exactly how much caffeine you are supplying to your body. It's crucial if you drink coffee and tea, which are sources of caffeine.

When combining these drinks with guarana supplementation, it is easy to overdose on caffeine and lead to side effects. The dosage that can cause overdose symptoms is mg of caffeine per day.

There may be about mg of caffeine in one guarana extract tablet.
