Source Naturals L-Theanine Description

  • 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.


Take 1 tablet 1 or 2 times daily, or as recommended by your health care professional.

I find this product extremely helpful in dealing with emotional issues related to menopause. It helps stabilize the mood swings related to menopause. April 8, 2013
Great Product! This seems to be the ideal dosage for me. I take before bed and just lay down and go to sleep. Works every time. December 9, 2011
I cannot say I found any benefit to taking this product. I thought it would enhance sleep, but it did not. November 6, 2011
Helpful for bedtime 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. March 19, 2009
helps you relax before you fall asleep. great product. September 17, 2008
