Guayusa - the Superfood from the Amazon Rainforest

We create KAMIDO by brewing tasty Guayusa leaves. We believe that Guayusa is the most unknown superfood with the strongest superfood profile. Guayusa has a unique balance of natural L-Theanine, caffeine and polyphenols – you will feel the natural energy, mental clarity and focus without feeling nervous. For us, it feels like meditation. 

Did you know that Guayusa tea have been consumed for more than 2000 years? Indigenous tribes from the Amazon Rainforest (especially the Kichwa Tribe) drink Guayusa as their morning ritual. 

We source our Guayusa leaves from families in Napo (Ecuador) that grow Guayusa in sustainable, biodiverse forest gardens, which are also called «Chakra». These chakras are self-sustaining ecosystems, which don’t require any pesticides or even fertilizers. Higher trees give important shade to the Guayusa tree. This chakra process is much more difficult than comparable industrial processes. However, we strongly prefer high quality ingredients instead of cheap ingredients which require pesticides and fertilizers. This natural approach is in line with our philosophy of «Health, Functionality and Sustainability».

Our Guayusa is EU organic farming certified.

L-Theanine - the Feeling of Meditation

 L-Theanine is a naturally occurring amino acid which was first discovered by the Japanese researcher Dr. Y Sakato. In Japan, L-Theanine plays an essential role in daily consumption, especially in tea.

Focus, Relaxation and Creativity
Studies have shown that L-Theanine triggers the release of alpha brain waves. These alpha brain waves lead to a state of mind, which also occurs during meditation as well as creative tasks. The release of alpha-waves enhances focus, relaxation and creativity. [11]

Anti-stress effects
L-Theanine may reduce anxiety and stress before a special situation (e.g. exam or contest). L-Theanine may help support the mental performance and studies suggest that L-Theanine could cause anti-stress effects. [6] [12]

Anti-inflammatory properties 
The study by Pardau et al. (2017, [9]) concluded that Guayusa is a «good source of dietary phenolic compounds with cellular antioxidant and anti-inflammatory properties».

Caffeine - worst enemy or best friend

Pure caffeine like in coffee or energy drinks could be your worst enemy. Caffeine interacts with neurotransmitters in the brain and can cause feelings like nervousness and anxiety. The release of epinephrine (adrenaline hormone) puts your body under stress. [10] However, in combination with L-Theanine, caffeine becomes your beloved friend. Guayusa contains caffeine, L-Theanine as well as valuable polyphenols. This special combination makes KAMIDO a superior option compared to coffee and energy drinks.

Better mental performance
According to the study by Haskell et al. (2008, [3]), the combination of L-Theanine and caffeine has shown to «promote faster simple reaction time, faster numeric working memory reaction time and improved sentence verification accuracy».

Lower increase in epinephrine
Coffee leads to release of epinephrine (adrenaline hormone) – you feel energized, but not better. Krieger et al. (2016, [7]) have shown that Guayusa «stimulated a significantly lower increase in epinephrine». This is why you feel energized, but in a good way.

Better mood
Schuster et al. (2019, [10]) conclude that «[…] compounds such as polyphenols, theobromine and L-theanine appear to enhance mood and cognition effects of caffeine and alleviate negative psychophysiological effects of caffeine».

Beware of synthetic caffeine
Most people think that caffeine is only a natural product found in coffee and tea. Unfortunately, almost all energy drinks contain synthetic caffeine which is created in labs. Synthetic caffeine is quickly absorbed, but will also lead to a quicker crash. KAMIDO goes the natural way and brews Guayusa leaves which contain natural caffeine.   

Scientific literature

We developed our product for over a year and made literally thousand different versions. All of them were not only based on nature's superfoods, but also science. We are nerds who love the most recent technology, but also want to live in harmony with nature.    

Our product development is based on the following randomized, double-blind,  placebo-controlled clinicial trials and studies.
