L-theanine is an amino acid found in tea leaves. Previous studies of dietary supplements of L-theanine have suggested a therapeutic benefit in reducing stress, promoting relaxation, and improving the quality of sleep.

Akiko Higashiyama, from University of Shiga Prefecture (Japan), and colleagues have found that daily L-theanine supplementation at 200 mg/day helps people with anxiety to focus on their daily activities.  The researchers recruited 18 healthy University students and assessed their anxiety levels using a standardised rating scale.  Student with high anxiety were put in one group, while students with minimal anxiety were put in another group. Both groups received water or water plus 200 mg of L-theanine per 100 ml of water. [1]
