Liposomal Guarana

Guarana contains compounds with antioxidant properties. These include caffeine, theobromine, tannins, saponins, and catechins.

Antioxidants are important because they neutralize potentially harmful molecules called free radicals. These molecules can interact with parts of your cells and cause damage linked to aging, heart disease, cancers, and other diseases.

Caco-2 cell and in vitro research published in 2022 showed that guarana’s antioxidant properties may defend against cholesterol concentration in the body and overall aid the clinical management of cardiovascular diseases.

Summary

Guarana contains caffeine, theobromine, tannins, saponins, catechins and other compounds that have antioxidant properties.

Guarana is best known as an ingredient in popular energy drinks. It’s an excellent source of caffeine, which helps you maintain focus and mental energy.

Caffeine works by blocking the effects of adenosine, a compound that helps your brain relax. It binds to adenosine receptors, preventing them from being activated.

Summary

Guarana is rich in caffeine, which can reduce fatigue and improve focus. Caffeine blocks the effects of adenosine, a compound that makes you feel drowsy and helps your brain relax.

A 2023 review of research indicated that guarana given over a short period may have an impact on cognitive performance. However, researchers note that it’s unknown if that impact is due to substances in guarana, such as caffeine.

They recommend additional research that involves a more in-depth look at those specific substances, including using equal doses of each when evaluating their effect on cognitive performance.

Summary

Low doses of guarana may aid cognitive performance.

According to the Centers for Disease Control and Prevention (CDC), an estimated 2 in 5 adults living in the United States has obesity.

Obesity is a growing concern and is linked to many chronic diseases, including heart disease, type 2 diabetes, and cancer. Guarana may have properties that help promote weight loss.

A 2019 study involved feeding rats either a Western or low fat diet with or without guarana supplementation over 18 weeks.

Results showed eating patterns with guarana supplementation prevented biological effects such as weight gain, insulin resistance, and adipokine dysregulation, which is a condition that leads to obesity and cardiovascular issues.

However, guarana’s effects on fat cell production as well as overall safety in humans remain unclear.

Summary

Guarana contains caffeine, which may aid weight loss by boosting metabolism. It has also been found to suppress genes that aid fat cell production and promote genes that slow it down. However, more human-based studies are necessary.

People in various parts of the world use guarana as a natural stomach tonic to treat digestive problems like chronic diarrhea and constipation. It may have anti-diarrhea properties because it’s rich in tannins or plant-based antioxidants.

On the other hand, guarana is rich in caffeine, which may act as a natural laxative.

Caffeine stimulates peristalsis, which activates contractions in your intestines and colon muscles. 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.

Summary

The caffeine in guarana may relieve constipation by stimulating contractions in your intestines and colon that push contents toward the rectum.

The CDC reports that heart disease is responsible for 1 in 5 deaths in the United States. Guarana may reduce the risk of heart disease in two ways.

First, guarana’s antioxidants may aid blood flow and prevent blood clots.

Second, in vitro and in Caco-2 cellular research published in 2022 indicates that guarana may decrease LDL “bad” cholesterol oxidation. Oxidized LDL cholesterol can contribute to plaque buildup in your arteries.

Summary

Guarana may aid heart health by improving blood flow and preventing blood clots. Research also indicates that it may be helpful in decreasing the oxidation of LDL “bad” cholesterol.

Historically, Amazonian tribes used guarana as a pain reliever. Its pain-relieving properties are due to its high caffeine content.

Caffeine plays a role in pain management by binding and blocking adenosine receptors. Two of these receptors, A1 and A2a, stimulate feelings of pain.

When caffeine binds to these receptors, it can reduce sensations of pain.

This is one reason caffeine is commonly found in many over-the-counter pain relief medications. Studies have shown it can significantly enhance their effects.

Summary

The caffeine in guarana may provide pain relief by blocking adenosine receptors, which stimulate feelings of pain.

Due to its strong antioxidant and antimicrobial properties, guarana is popular in the cosmetics industry as an ingredient in creams, lotions, soaps, and hair products.

Moreover, its caffeine content may aid blood flow to the skin. Caffeine is metabolized in the body into certain pharmacologic agents, such as theobromine. Theobromine expands blood vessels, increasing blood flow, which is important for the skin’s function. However, higher quality studies are still necessary to fully determine the effects of caffeine on the skin.

Summary

Guarana has antioxidant and antimicrobial properties, making it a common additive in cosmetic products. It may aid blood flow to your skin.

Guarana contains many compounds that may inhibit or kill harmful bacteria. One bacteria type 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.

Summary

Guarana contains compounds that may inhibit or kill harmful bacteria, such as E. coli.

Vision changes often occur during the natural aging process. Sunlight, dietary issues, and certain lifestyle choices, such as smoking, can negatively affect 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 2017 study found that people who regularly consumed guarana had better self-reported vision than those who consumed it sparingly.

That said, limited research exists on guarana and age-related eye disorders. More human-based studies are necessary.

Summary

Studies have found that guarana may defend against oxidative stress, which links to age-related eye disorders. However, there are limits to this area of research, so more human-based studies are necessary before providing recommendations.
