Guarana has gone from being a plant with long traditions in the Amazon to becoming an ingredient used in products all over the world. The high content of natural caffeine is the main reason for its popularity, but the seeds also contain several other bioactive compounds.

How is guarana produced, and what does it actually contain? Here we take a closer look at the plant's origin, content, and use.

What you should know about guarana

What is guarana, in short?

Guarana is a climbing plant from the Amazon that is primarily cultivated in Brazil today.

How is guarana powder and extract made?

It is the seeds that are used to produce guarana powder and guarana extract.

Guarana is one of the richest natural sources of caffeine and typically contains 3-6 percent caffeine.

The seeds also contain theobromine, theophylline, and polyphenols such as catechins, proanthocyanidins, and tannins.

In Brazil, guarana is used in both traditional foods, drinks, and the popular soda Guaraná Antarctica.

Outside of Brazil, guarana is primarily used in dietary supplements, pre-workout products, and certain energy drinks.

Many products combine guarana with other ingredients, such as taurine, vitamins, and plant extracts.

A high intake of guarana can cause the same side effects as a high intake of caffeine, including restlessness, palpitations, and sleep disturbances.

Where does guarana come from?

Guarana (Paullinia cupana) belongs to the soapberry family (Sapindaceae) and is a perennial climbing plant that grows naturally in the Amazon, primarily in Brazil.

The plant thrives in a warm and humid climate and is now commercially cultivated, especially in the states of Amazonas and Bahia.

When the fruits ripen, the red shell splits open, revealing a dark seed surrounded by a light seed membrane. The characteristic appearance has given the plant the nickname "the eye of the Amazon."

Guarana has been cultivated by the Sateré-Mawé people for several hundred years, and they are considered the original cultivators of the plant.

Today, Brazil accounts for the vast majority of the world's commercial production.


From seed to raw material

It is the seeds that are used to produce guarana products.

After harvesting, the seeds are separated from the fruit pulp before being washed, dried, and roasted. Roasting helps develop flavor and aroma, while also making the seeds easier to grind.

They are then ground into a fine powder or used to produce guarana extract, which is utilized in dietary supplements, energy drinks, and certain foods.

In the production of guarana extract, the content is often standardized so that the amount of caffeine is as consistent as possible from batch to batch. This makes it easier to create products with a uniform content of active ingredients.

What does guarana contain?

Guarana is one of the richest natural sources of caffeine.

The seeds typically contain between 3-6 percent caffeine, which is about two to four times more than coffee beans. The content can vary depending on factors such as plant variety, growing location, cultivation conditions, and processing.

The high caffeine content applies to the seeds themselves, while the amount of caffeine in finished products depends on how much guarana they contain.

In addition to caffeine, guarana contains the methylxanthines theobromine and theophylline, which have a chemical structure related to caffeine. Both have mild stimulating properties but are present in much lower amounts than caffeine and therefore contribute less to the overall effect.

The seeds are also rich in polyphenols, including catechins, proanthocyanidins, and tannins. The polyphenols act as natural antioxidants, and the tannins also contribute to the characteristic bitter taste.

Who should be careful with guarana?

Guarana is primarily used due to its high caffeine content, which can contribute to increased alertness and reduced feelings of fatigue.

At the same time, the effect will depend on how much caffeine the product contains and whether it is combined with other sources of caffeine in the diet.

A high intake of guarana can cause the same side effects as a high intake of caffeine, including palpitations, restlessness, sleep disturbances, and an upset stomach.

Individuals who are sensitive to caffeine, as well as pregnant women and people with certain heart and vascular diseases, should therefore be cautious with products containing guarana.
