L-Theanine Supplement

L-Theanine is a non-protein building amino acid, derived from green tea. It safely promotes relaxation and natural stress relief without the side effects commonly seen with other relaxing agents, such as drowsiness and dullness. Soon after taking L-Theanine, a restful state takes effect without reducing alertness or cognitive ability.

An amino acid derived from the tea plant (Camelia sinensis), L-Theanine works to relieve stress and occasional anxiety. It can also offset the harsh and confusing effects of the stress hormone known as cortisol on the brain and nerves – with this ability, L-Theanine supplements may help decrease cravings for comfort food, making it highly beneficial for beginning a diet. In addition, L-Theanine may help improve your quality of sleep when taken at night.

Our innovative formulation of this natural relaxant helps clear the noise from an overly-excited mind by improving focus, creativity and aptitude. L-Theanine may support focus in adults and teens with ADHD by improving focus and reducing nervousness.*

Expert Discussion

Japanese researchers recruited healthy University students and assessed their anxiety levels using the manifest anxiety scale (MAS). Students with high anxiety were put in one group, while students with minimal anxiety were put in another group. Both groups received water or water plus 200 mg of L-Theanine. The test was performed repeatedly and assessments performed between 15 and 60 minutes after ingestion. Results showed that highly anxious students receiving the L-Theanine displayed a slowing of their heart rate, improved attention performance, and better reaction times, compared to members of the same group receiving the placebo. No significant benefits were observed in the students with minimal anxiety. “It is noteworthy to mention that unlike other conventional anti-anxiety treatments, L-Theanine did not result in increased drowsiness, slowed reflexes, or impaired concentration,” wrote the authors. “Results of a present study showed that ingestion of 200 mg of L-Theanine changes the electrical activity in the brain by increasing alpha electric band measured by EEG.” This study is published in the Journal of Functional Foods. http://www.invitehealth.com/l-theanine-helps-academic-performance-of-anxious-students/radio/2011/05/

What is L-Theanine?
L-Theanine is an amino acid that comes from the tea plant, but it does not build protein. Instead, it works to reduce stress and anxiety. Soon after taking L-Theanine, a restful and relaxed state sets in while maintaining alertness. L-Theanine is free of the side effects commonly seen with other relaxing agents, such as drowsiness, impaired thinking and decreased motor skills.

L-Theanine clears the noise out of an overly excited brain by improving focus and creativity. L-Theanine may help adults and teens with ADHD by improving focus and reducing nervousness. In addition, when taken in higher doses, it can help improve the quality of sleep.

L-Theanine may offset the harsh, confusing effects of cortisol, a stress hormone, on the brain and nerves and in this way may help decrease craving for comfort foods. This may be helpful for a person who is starting a diet.

I have been using L-Theanine and it already has made a difference in my life. It clams me down and helps me with stress. As a matter of fact, I have been using it for three months only.
