L-theanine is a unique free form amino acid found only in the tea plant. L-theanine creates an alert yet totally relaxed state of mind without drowsiness.  L-theanine is clinically proven to reduce stress, improve the quality of sleep, diminish normal syptoms of PMS, heighten mental acuity and reduce negative side effects of caffeine.

Theanine is an analog to glutamine and glutamate, and can cross the blood-brain barrier.It is sold in the US as a dietary supplement and is FDA confirmed as GRAS. The Japanese Ministry of Health and Welfare approved the use of L-theanine (the levorotary enantiomer of theanine) in 1964.
