L-Theanine is an amino acid that can be found in tea leaves - you’ve probably heard about it if you’re a big fan of green tea or matcha. It is known for its ability to create a calming effect on the brain by increasing alpha brain waves (this is the good stuff that shows you are drifting deeper into sleep).

This powerful ingredient helps promote relaxation and restful sleep in an interesting way - it does not act as a sedative, but rather lowers anxiety levels and promotes relaxation by decreasing the levels of excitatory chemicals in your brain. This means you will be able to fall asleep faster and spend more time dreaming.
