L-Theanine is a naturally occurring amino acid found in green tea leaves. It has been found to promote relaxation without drowsiness, easing nervousness due to overwork and fatigue, and support calmness.

Thanks to its high bioavailability and simple uptake into the brain, supplementation with L-theanine has been shown to be effective for inducing a variety of psychologically beneficial properties, including stress support (relaxation) and promotion of cognitive function.
Research also suggests that L-theanine administration significantly increases alpha waves in the brain, without decreasing beta waves, thereby inducing relaxation without sedation. Alpha waves are one of the two most frequent types of waves produced in the brain when we are awake, with the other being beta waves.
People who are in a resting state or coming down from a busy set of activities are often in the alpha brain wave space. People who practice light meditation will also be functioning in the alpha brain level.
When we are highly involved, active, or engaged in difficult mental activities your brain waves are functioning at the beta level. Thus, when L-theanine is ingested, users tend to feel more calm but yet attentive.

I just started taking this supplement a month ago but it is really helping me relax and fall asleep sooner. I have tried numerous other sleep aids and nothing seemed to help but ambience and I don't want to take that.

L Theanine helps!
I take L Theanine at bedtime. I have 1 on my bedside if I wake up and am unable to sleep. It must relax me because I fall asleep! I have also taken 1 before a very stressful event and I felt calm and sharp mentally. Great product.

Quality Supplement
I take L-Theanine at times when I feel stressed and when I'm dealing with high anxiety. I feel this supplement helps me focus, relax and calms my moods. If I have high anxiety throughout the day I will take one capsule before bedtime, it calms my mind and helps me sleep. I definitely recommend this supplement.
