Natural Caffeine (stimulant)
One of the most studied stimulants.
Caffeine has been proven to reduce fatigue and boost cognitive ability. However, caffeine is not perfect. It destroys the ability to focus by increasing the heart rate and triggering adrenaline hormones. Even though caffeine is consumed as a daily fuel by many, it is more suitable for physical than mental performance.
Natural L-Theanine (relaxant)
An uncommon amino acid in the western diet.
It is a relaxant derived in highest concentration from the Japanese Matcha tea. L-theanine inhibits stress hormones and promotes a calm, but alert state of mind by boosting alpha brainwaves. This state can be reached by meditation and this is why Matcha is consumed daily by monks in Japan.
Synergy of Caffeine and L-Theanine
Multiple studies prove that L-theanine neutralises the negative side effects of caffeine and leaves you only with the benefits of each ingredient. Stacking L-theanine with caffeine boosts your brain function, focus & mood. Consuming caffeine with L-theanine is therefore perfect for helping you to be more productive and achieve more during the day.
Gradual release without energy spikesThe natural ingredients contain fiber which ensures a gradual absorption of active ingredients so there are no energy spikes or crashes. Therefore, the boost lasts longer than after consumption of a cup of coffee or an energy drink.
