Nootropic Properties

Can increase levels of GABA, Dopamine and Serotonin in the brain, which may contribute to state of wellbeing, whilst easing tension and stress (4).
L-Theanine has been proven to stimulate Alpha Waves in the brain, especially in the posterior portions of the cortex, thus producing a feeling of relaxation, which is directly equivalent to how one would feel after meditating/meditation (6, 7).
Reduces the jitters from caffeine and other stimulants (8).
Enhances reaction time (9).
Enhances short term memory (10).
Increases BDNF expression and NGF (Nerve Growth factor), which mimics the response of exercise in the brain (11), leading to profound effects on improving neurogenesis and neuroplasticity.
Does not act as a GABA agonist, thus does not possess addictive potential nor will it cause any downregulation of GABA receptors (12).

Stress

Decreases cortisol, the body’s master stress hormone, which can lead to low mood, poor ability to cope and general feelings of helplessness (1, 2).
Can calm down a racing mind at night, and thus promote healthy sleep quality (3).
Lowers glutamate, which may prevent excitotoxicity (death of brain cells) (20).

Longevity

Quite possibly through a reduction cortisol, L-Theanine may display anti-obesity effects (8).
Extends lifespan in worms (14).
Supports a strong, healthy immune system (15).

May improve cardiovascular functioning, via increasing eNOS phosphorylation (18).
Can remedy adrenal fatigue symptoms, by suppressing adrenal hypertrophy (19).
Regeneration of atrophied intestinal tissue in rats (28).
