Helps Reduce Anxiety. Suitable for Vegetarians. L-Theanine is a unique amino acid found almost exclusively in the tea plant (Camellia sinensis) and is the primary ingredient contributing to the unusual taste of green tea. Animal studies have shown that L-theanine crosses the blood brain barrier increases dopamine and GABA levels in the brain and inhibits the stimulatory properties of caffeine. Human studies have shown that taking L-theanine results in the emission of brain waves associated with a state of relaxation.

"My Integrative Medicine Doctor recommended this for anxiety, as needed. I like to take it 20 minutes or so before bed, with my nightly Calcium (it works even better this way) and I start feeling relaxed and sleepy soon. If I don't go to sleep when I start feeling that way, it passes, so I time it when I am close to turning off the lights for the night! Absolutely worth trying and the price is about half what you'd pay in a health food store."
"I read an article on a study that was done in Japan using L-Theanine to help people get better rest. So, I saw that Vitacost had the product and I ordered some. I have been using it for over a year. I can honestly say that taking just one tablet per night has helped me tremendously. I am finally getting the deep sleep that I haven't had in years. I have reccommened this product to a number of my friends and they have all said that it has helped them as well. I would give this product a 5 start rating."
