1. What is the Guayusa plant

The Guayusa plant is a holly tree native to South America, more than 90% in Ecuador. It belongs to the ilex family and is therefore related to yerba mate in the broadest sense - you can find a comparison here . Guayusa is used by the natives of Ecuador as a natural stimulant or pick-me-up. The reason for this is the unique composition of ingredients, which differs enormously from other caffeinated drinks.

Guayusa is not related to plants like guarana, green tea or guava. Despite what many might think based on the name. It is a fundamentally different type of plant with a different taste and a new kind of special effect. You can find out more information about the Guayusa plant in our detailed article " What is Guayusa ?".

In addition, Guayusa has the ingredients theobromine and theophylline from the cocoa bean and L-theanine , an amino acid with a particularly focusing effect, from the vital mushroom Boletus badius .

Guayusa tea ingredients and effects overview

3. Guayusa tea effect

Guayusa is a caffeinated drink and yet its effect differs from well-known pick-me-ups such as guarana, yerba mate, black tea, coffee and green tea. The special effect of guayusa is due to the composition of the ingredients, which can only be found in this composition in the guayusa plant.

The Guayusa tea effect can best be described using the words of the natives of Ecuador. They say guayusa keeps them awake for several hours , focusing the senses and mind while having a calming and stress- reducing effect .

More alert, more focused, more relaxed – the Guayusa effect!

These 3 properties best describe the Guayusa tea effect ! The infusion of the Guayusa plant or the leaves is correspondingly interesting for all those who have to concentrate, motivate and work as stress-free as possible for a long time or who have to perform in general, for example in sports and studies !

3.1. Performance enhancing and awakening

The ingredients caffeine, theobromine and theophylline in particular ensure a performance-enhancing effect, which lasts for several hours in combination. Guayusa tea has, for example, the following performance-enhancing effects:

  1. stimulation of the heart
  2. stimulation of the airways
  3. Improved oxygen uptake
  4. Improved blue light capture
  5. Reduction of melatonin
  6. Increases memory performance
  7. Improves memory

3.2. Guayusa tea effect metabolism

According to two studies, the metabolism is boosted by the caffeine in guayusa between 3% and 11% , this can have an enormously positive influence on your calorie turnover and allow you to perform significantly better, especially in sports.

However, an improved metabolism also helps you to be able to absorb and use the energy in the meal more quickly. The Guayusa tea effect on the metabolism therefore contributes positively to the wake-up effect.

3.3. Guayusa tea for weight loss

Of course, the effect of Guayusa tea on the metabolism also has an impact when it comes to losing weight. Caffeine has been shown to increase fat burning by up to . However, this is the absolute peak value that should not be relied on alone when losing weight.

Incidentally, GUYA founder Sebastian Freidank has created a success course for nutrition, mindset and sport that provides you with a complete package.

If you are interested in the effects of guayusa tea on losing weight, let us tell you at this point that there is no miracle pill (yet). There is no guarana, green tea, matcha, extracts or pills that will make you lose weight miraculously. This requires the three factors mentioned above. Diet is one of those factors and the Guayusa tea effect can definitely help you lose weight!

3.4. Stomach-friendly tea – effect of the Guayusa plant

Guayusa is one of the gentlest teas on the stomach. It is basic and contains no acids. Coffee, on the other hand, contains a lot of caffeic acid. This additional acid in coffee causes many people stomach problems in the long run.

Guayusa, on the other hand, can be drunk first thing in the morning even on an empty stomach and has a calming effect even on irritated digestion.

3.5. Sleep despite caffeine

Here, too, the Guayusa tea effect differs from other caffeinated drinks!

With guayusa containing so much caffeine, up to 7.6%, it's only logical to think that guayusa affects sleep in a hugely negative way. However, the exact opposite is the case! Despite the high caffeine content, Guayusa lets the body rest when it needs it!

This exciting and helpful effect is due to the natural combination of the active ingredients L-theanine and caffeine. The L-theanine balances the aggressive effects of caffeine on the cardiovascular system, allowing it to act primarily on the central nervous system.

Even the natives of Ecuador use Guayusa shortly before sleep to stimulate dreams . You can find an interesting article on the use of Guayusa by the indigenous people here .

3.6. Drink healthy

Guayusa tea has about twice as many antioxidants as green tea , making it one of the world's healthiest foods. Antioxidants scavenge free radicals and thereby protect our body from oxidative damage.
