Health Benefits of the Guarana Extract

Antioxidant activity

Research has shown that the Guarana extract contains several compounds that serve as antioxidants. These compounds typically include saponins, catechins, theobromine, caffeine and tannins. The antioxidant action of the mentioned compounds is associated with various functionalities.
It is pretty interesting to note that the functionality of the antioxidants by Guarana extract is similar to that of green tea.
The body consists of several molecules that may be harmful and may cause oxidative stress. These molecules are known as free radicals. Antioxidants in Guarana extract help to inhibit the functionality of these free radicals and protect you from various conditions such as signs of aging, heart disease, fatigue etc. The anti-aging characteristics of the Guarana extract are well noted. In addition, the antioxidant action of Guarana extract may potentially inhibit the abnormal growth of cancerous cells as you age. This has been evidenced by studies.

Stimulant action

Guarana extract is a rich source of several stimulants such as caffeine, theobromine and theophylline. Here, it is worth putting special focus on caffeine as it is the most widely known stimulant in the world. The seeds of the Guarana plant have around 6 times more caffeine than coffee beans!
The stimulants in the Guarana extract work by inhibiting the functionality of adenosine, which is a chemical compound that helps to relax your brain’s activity. This inhibition is achieved by the build-up of an interconnection between the stimulant (say, caffeine) and the adenosine receptors. This prevents the triggering of the adenosine receptors and your brain feels more alert and focused.
An experimental study has demonstrated that subjects who took a supplement containing Guarana extract ended up feeling less exhausted and more energetic when compared to subjects who took a placebo.
Studies have also indicated that the consumption of Guarana by cancer patients helps them to keep away fatigue.

Some studies on animals have proved that Guarana extract can improve memory and information retention abilities.

Good for the stomach

Guarana has a long history of being used to treat various stomach conditions such as upset stomach, diarrhea and constipation. We have mentioned the antioxidant properties of tannins. Medical studies have demonstrated the ability of tannins to make the inner lining of your intestines waterproof.

An interesting aspect of caffeine is its ability to stimulate peristalsis, thereby triggering the muscular contractions of your digestive tract. This process aids in dealing with constipation as it forces the bowels into the rectum.

Helps in weight loss

Studies have indicated that caffeine helps to accelerate your rate of metabolism by more than 10% in the duration of half a day. With a higher metabolic rate, thermogenic effects burn your unwanted fat deposits and calories.
Various studies in a test-tube have shown that Guarana extract inhibits the production og genes that aid in fat cell functionality. In addition, it also facilitates genes that decelerate the production of fat cells.

Maintains good cardiovascular health

The rich content of antioxidants in Guarana help to promote the proper flow of blood through the blood vessels, and prevent blood clots. This has been established by studies.
Further studies have shown that consuming Guarana helps in preventing the build-up of Low Density Lipoprotein (LDL) cholesterol, that is, the bad cholesterol within the blood vessels.
All of this contributes towards good cardiovascular health.

Helps to relieve pain

The ability of Guarana to provide pain relief is well-documented. The caffeine content in Guarana inhibits the adenosine receptors that are responsible for pain. This potent functionality of caffeine in Guarana has made it a common inclusion among the list of ingredients in many pain relief medications.

Improves the quality of your skin

Once again, the high caffeine content in Guarana comes into the picture. Studies have demonstrated that caffeine facilitates the flow of fresh blood into the skin. This helps in improving the appearance of your skin and make it free from blemishes, marks and acne.
Guarana may also help in fighting the signs of aging in skin. Further studies show that Gauarana tones the skin, improves the skin’s texture, prevents sagging of the skin and makes it look younger.

Studies have displayed that the consumption of Guarana extract helps to combat age-related eye conditions such as glaucoma and macular degeneration. In addition, studies also show that subjects who consume Guarana on a regular basis reported better vision than those who did not. As such, Guarana extract protects your eyes against potential damage and also helps to maintain good eye health for all age groups.
