THE SCIENCE

Caffeine

One of the most studied and well known stimulants. 

Caffeine has been proven to reduce fatigue and boost cognitive ability. However, caffeine is not perfect. It destroys your ability to focus due to increased blood pressure and adrenaline. Even though caffeine is consumed as a daily fuel by many, it is more suitable for boosting physical energy than mental performance. It is for this reason caffeine is consumed before high intensity physical exercises in a form of a 'pre-workout' drink.

L-Theanine

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 & L-Theanine

Brite contains 150 mg of Caffeine and 150 mg of 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.

The natural ingredients are released gradually 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.
