L-theanine is an amino acid known for its calming and grounding properties. It increases alpha brain waves associated with “wakeful relaxation.” This non-protein amino acid is commonly found in tea leaves. Research suggests that L-theanine benefits the brain by modulating GABA, glutamate and dopamine neurotransmitters. L-theanine has been shown to increase alpha brain wave activity. It improves stress management, lowers cortisol levels, counteracts caffeine overstimulation, and improves cognition. It is also a non-sedating sleep inducer.
