I have gathered a bit more info on L-theanine and would like to share it with those interested in this approach. L-theanine has just recently been introduced to the U.S. market. Japan is credited with most of the clinical studies and information we possess thus far on L-theanine but research is ongoing. In a study done in 1999 at the University of Shizuoka in Japan, several unique properties of L-theanine were found. The research demonstrated that in addition to facilitating relaxation, L-theanine may benefit learning performance, mental clarity, concentration, and immunity. And, unlike tranquilizing drugs, it doesn’t interfere with the ability to think. Studies on rodents show just the opposite: theanine enhances the ability to learn and remember. By shutting down the “worry” mode, theanine increases concentration and focuses thought. It has also been used with great effectiveness to relief premenstrual syndrome. Effects should be noticable 40 minutes after taking the capsule. It can be taken on a full or empty stomach; capsule can also be opened and poured into a drink. L-theanine is extremely safe. There are no dietary limits on L-theanine intake by the Japan Food Additive Association. In 1964, the Japanese Ministry of Health and Welfare approved L-theanine for unlimited use in all foods, with the exception of infant foods.

People under stress can mitigate many of the harmful effects of stress with L-theanine without becoming sedated in the process.

L-theanine doesn't make one drowsy, nor does it promote sleep because this amino acid does not produce theta waves in the brain.

It should be noted that if an individual were already relaxed, taking L-theanine would not produce further relaxation.
