The most important facts in a nutshell
- Guarana powder is extracted from the plant Paullinia cupana . The fruits contain seeds that have a very high caffeine content. These seeds are used to make guarana powder, which is more concentrated than regular coffee.
- Due to its energy-giving effect, guarana is often added to chocolate or soft drinks. This addition also drowns out the naturally bitter taste of guarana.
- Thanks to the tannins, the effect of guarana is slower but longer. The tannins first have to be broken down by the body, so the caffeine is only released in the intestines and does not attack the stomach.

Buying and evaluation criteria for guarana powder
When buying guarana powder, you should pay attention to various aspects, such as:
By making the right choice for you, you can save money and also ensure that you don't give your body anything it doesn't need. Therefore, always look for high quality and ask to see the manufacturer's certificates if necessary.
The most important thing when buying guarana powder is that it tastes good. After all, you should take the powder several times a week or even daily. There is no question that you should enjoy the consumption. Guarana powder is a rather difficult product in terms of taste. The powder often tastes a little "earthy". Some also describe guarana powder as tart or bitter. This is easily remedied by adding it to a smoothie or similar.
Ingredients / additives
The fewer additives guarana powder contains, the healthier it is. Preservatives, fillers or binders reduce the healthy effect of the powder and should therefore not be present. It is also important to make sure that the guarana powder consists of 100 % guarana. If sugar or similar ingredients are also present, the result can quickly be falsified or also become unhealthy.
Compatibility goes hand in hand with the ingredients of the powder. This criterion is particularly relevant for allergy sufferers. If the guarana powder consists of 100 % guarana, it is lactose- and gluten-free. However, care must also be taken during production to ensure that it does not come into contact with certain foods such as nuts. This is an important aspect due to the high reaction of nut allergy sufferers. In addition to tolerance due to allergies, voluntary renunciation of animal food is also an important point. Guarana powder should always be vegetarian and vegan and therefore suitable for vegans.
Related to taste is often how well the powder dissolves in water or other liquid. If the product does not dissolve or forms lumps, they often do not taste good when consumed. Therefore, make sure that the powder has good solubility and does not leave any residues. There is also the possibility of removing the set of the powder as in making coffee.
Guide: Frequently asked questions about guarana powder answered in detail
In order to inform you comprehensively about the effectiveness of guarana powder and to give you an understanding of the current state of science, we have summarised all the important information in the following sections.
What is guarana powder and how does it work?
Guarana powder thus basically acts like coffee as a wake-up stimulant. The high caffeine content is perfect as an energy supplier. When consumed, it has been proven to increase cognitive performance and reduce mental fatigue.(1)
The caffeine content in guarana is many times higher than in regular coffee beans. Fatigue is prevented not only by caffeine, but also by the theobromine and theophylline it contains. In one study, it was shown that the subjects' memory performance was increased and they were more alert and attentive.(2)
Guarana is also said to have calming properties and relieve stress. In addition, it can have positive effects on your mood, according to a study. (3) It is also unusual to find that guarana can reduce anxiety and panic, as caffeine is usually considered to be more of an agitator.(4) This is because caffeine stops the neurotransmitter adenosine. Adenosine is normally responsible for the brain's resting phases and prevents the happiness hormone serotonin from taking effect. Caffeine thus contributes to the absorption of the happiness hormone and the subject is likely to be more cheerful.(3)
As one study points out, guarana combined with ginseng enables you to fully utilise your energy and maximise your performance. The absorption of information is said to be significantly improved. In addition, there is a higher blood circulation, which has a positive effect on the brain and headaches.(5) The positive effects on performance and mood are also maintained in the combination of guarana and aspirin.(6)
Better digestive system
Guarana is positive for the digestive system because the tannins mean that it only takes full effect in the intestines. It has been used before as a natural remedy for flatulence and diarrhoea. It has been found that high blood pressure and metabolic disorders occur less frequently when people consume guarana regularly.(7)
Antioxidant and antimicrobial
Studies have also found that Brazilian-derived guarana can significantly fight food poisoning, bacteria and fungi.(8) It has been dubbed a promising antioxidant in the food industry. The intake of dietary fibre, especially pectin, has proven to have a positive impact on human health. This is explained by its antioxidant and hypocholesterolemic effects.(9)
What are the ingredients of guarana powder?
|Caffeine||2.4 to 5 percent|
|Tannins||5 to 14 percent|
|Polysaccharides||30 to 47 percent|
|Theobromine||0.02 to 0.04 percent|
|Theophylline||0 to 0.025 percent|
|Proteins||7 to 8 percent|
|Sugar||6 to 8 percent|
You should make sure that no additives or similar have been added.
When and for whom is it useful to take guarana powder?
During pregnancy or breastfeeding, guarana, like any other caffeinated drink, should be avoided. The caffeine is broken down more slowly here and thus remains in the body much longer, whereby side effects can occur. If you suffer from high blood pressure or are too young, taking guarana is also not advisable. If you are taking other medicines, make sure you check whether their effect can be altered by the consumption of guarana. Guarana can influence the metabolism of medicines and thus pose a great risk to health.(11)
How quickly and how long does guarana powder work?
What are the side effects of guarana powder?
- high blood pressure
- strong heart palpitations
Long-term overdose can also cause cardiovascular problems. However, most teas and energy drinks containing guarana usually contain a harmless amount. (12) There have been no incidents of negative effects associated with common energy drinks. However, attention should always be paid to the sugar and caffeine content in sweet drinks, as these are often above the recommended limit.(12)
What is the difference between guarana and coffee?
The effect of coffee usually takes effect after 15 to 30 minutes, but with guarana it takes longer. On the other hand, the effect of guarana lasts longer and also more evenly, thus providing good conditions for learning.
