Guarana: What is it used for?

The main benefits of guarana are:

1. Combating physical and mental fatigue
Guarana is rich in caffeine, which acts directly on the brain, blocking the effects of adenosine, a substance that causes sleepiness.

In addition, the caffeine in guarana has a stimulating effect, increasing the release of neurotransmitters such as adrenaline, noradrenaline, dopamine, glutamate, and serotonin, which helps combat physical and mental fatigue.

2. Increasing alertness and concentration
Due to the caffeine present in its composition, as well as theobromine and theophylline, guarana can also increase alertness and concentration, which can be useful for improving reasoning, focus, speed of information processing, and disposition for studies or work, for example.

3. Helping with weight loss
The caffeine in guarana can increase metabolism and fat burning, causing the body to expend more energy.

Therefore, guarana, when used as a supplement and combined with a balanced diet and physical activity, can aid in weight loss. See how to create a balanced diet.

Furthermore, since guarana reduces physical fatigue, a person may have more energy for physical activity, which also contributes to its effect on weight loss.

4. Improve mood
Guarana can also help improve mood by stimulating the production of neurotransmitters, such as serotonin and dopamine, which are responsible for regulating mood and feelings of well-being, and can be useful in helping to combat depression and anxiety, for example.

5. Improve skin appearance
Guarana has a large amount of antioxidants that fight free radicals, thus preventing the appearance of wrinkles, sagging, and premature aging, and improving the appearance of the skin.

6. Preventing Cardiovascular Diseases
Guarana is rich in antioxidant substances, such as caffeine and catechins, which help inhibit the formation of blood clots and improve blood flow, which can help prevent cardiovascular diseases such as heart attack, thrombosis, or stroke.

In addition, the antioxidants present in guarana help regulate cholesterol levels, especially "bad" cholesterol (LDL), which also contributes to the prevention of cardiovascular diseases.

Guarana has some properties similar to green tea, mainly because it is rich in catechins, which are antioxidant substances. See more about the benefits of green tea and how to use it.

7. Relieving Gastrointestinal Problems
Guarana has anti-diarrheal and laxative properties which can help relieve gastrointestinal problems such as chronic diarrhea or constipation.

This is because guarana contains tannins, which are astringent and capable of absorbing water from the intestines, and when ingested in small quantities, it can combat diarrhea.

When used in large quantities, the caffeine present in guarana can stimulate bowel movements, having a laxative effect and thus helping to relieve constipation.

8. Combat headaches
Guarana can help relieve tension headaches because caffeine helps relax muscles and improve blood flow to the brain.

Therefore, many headache remedies contain caffeine in their composition. See the main headache remedies.

9. Reduce pain perception
Guarana has analgesic properties due to the caffeine present in its composition, which blocks the action of adenosine, a substance that is also involved in pain.

In this way, guarana can help reduce the perception of pain.

10. Aiding in the fight against cancer
Some laboratory studies conducted with rats and liver, colorectal, and melanoma cancer cells have shown that the antioxidant substances in guarana may help reduce the proliferation or increase the death of cells of these types of cancer.

However, studies in humans are still needed to confirm this benefit. Check out the complete list of foods that help prevent cancer.
