Suntheanine is a brand name for L-theanine. L-Theanine is an amino acid found in green tea. Studies have shown that this amino acid reduces the stress response and creates a 'relaxed state' of the mind.

There are several ways in which L-Theanine works to calm down the mind. L-theanine stimulates the production of alpha waves in the brain, which promote relaxed and alerted state of the mind. The action is similar to that of mind-calming conventional medications, but without their side effects.

Another way in which L-theanine promotes mental calmness is by promoting the formation of GABA neurotransmitter. L-theanine takes part in the formation of GABA, which has a natural calming effect on your brain. GABA also helps in improving the quality of sleep.

Due to these calming effects, Theanine is useful in enhancing cognitive and learning abilities, improving performance and mental acuity, and boosting immune system.
