What is L-theanine?

L-theanine is an amino acid primarily found in green tea. Studies show it is able to cross the blood-brain barrier, and it's found to reduce anxiety by blocking excitatory stimuli at glutamate receptors in the brain while stimulating the production of the inhibitory, relaxing neurotransmitter GABA.

There is a connection between anxiety, reaction to stress, and the brain’s most fundamental function, sustaining cognition. The most recent studies suggest a role for L-theanine in supporting cognitive function and preventing its loss.

That means that, at the same time as being recognized for its ability to calm the mind, it's also shown to produce a state of "alert relaxation".
