What are the properties of Theanine in supplements?

The properties of Theanine

Theanine (C₇H₁₄N₂O₃) – amino acid, typically found in green tea, studies suggest that theanine improves learning and memory. Theanine may have a neuro-protective effect on the brain, and appears to stimulate the same brain waves that are activated when you meditate.

Studies looking at the effects of both L-theanine and caffeine have found a rise in focus, motivation, and mood, improved alpha wave levels (a sign of relaxation), and reduced heart rate and blood pressure. It seems as though adding theanine to the mix negates many of the side effects of excessive caffeine usage while enhancing the positives. More about Theanine on Stress Management Basics: L-Theanine.

L-Theanine:

Promotes sleep quality (In search of a safe natural sleep aid).
Increases alpha brain waves (L-theanine, a natural constituent in tea, and its effect on mental state).
May regulate stress levels (L-Theanine reduces psychological and physiological stress responses).
May improve performance on cognitively demanding tasks when combined with caffeine (The combined effects of L-theanine and caffeine on cognitive performance and mood).

  Conclusion: Caffeine was found to mainly improve performance on demanding long-duration cognitive tasks and self-reported alertness, arousal, and vigor. Significant effects already occurred at low doses of 40 mg. L-theanine alone improved self-reported relaxation, tension, and calmness starting at 200 mg. L-theanine and caffeine combined were found to particularly improve performance in attention-switching tasks and alertness, but to a lesser extent than caffeine alone. No conclusive evidence relating to effects induced by EGCG could be given since the amount of intervention studies was limited. These studies provided reliable evidence showing that L-theanine and caffeine have clear beneficial effects on sustained attention, memory, and suppression of distraction. Moreover, L-theanine was found to lead to relaxation by reducing caffeine induced arousal.
