Benefits
Together, L-theanine and Caffeine are considered one of the most commonly used and popular nootropic stack options for beginners. Many would consider L-Theanine to be the most versatile “natural smart drug” that can be used alongside other herbs and substances. The pharmacological implications of supplementing L-Theanine has a wide variety of applications. Over 145 scientific studies have been done on L-Theanine according to Pubmed. Scientific Name: Gamma-ethylamino-L-glutamic acid
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).
