L-Theanine
Promoting a Calming and Mood-Enhancing Effect
Supplement Facts
For you, if you are interested in a non-toxic mood regulator
The ingredients in L-Theanine can:
Encourage relaxation and well-being by helping to support a healthy stress response
Promote brainwave patterns similar to massage
Support production of gamma-aminobutyric acid, the neurotransmitter that influences levels of dopamine and serotonin
L-theanine is an amino acid found in tea and has been shown in several studies to support calming effects by favorably modulating several aspects of brain activity.
What is L-theanine?
Theanine is an amino acid primarily found in tea. Studies show it can cross the blood-brain barrier, and it's found to reduce anxiety by blocking excitatory stimuli at glutamate receptors in the brain while stimulating the production of the inhibitory, relaxing neurotransmitter GABA. (1)
The calming effects and benefits of L-theanine
Its benefits have been known around the world for centuries, particularly in East Asia. While ancient civilizations may have referred to L-theanine by different names, they understood and utilized its impact. (2)
L-theanine is shown to produce calming, mood-enhancing effects by encouraging electrical brain activity commonly present when you are very relaxed, which sets you in a better mood.
Moreover, L-theanine can modulate the formation of gamma amino butyric acid GABA (gamma amino butyric acid), a neurotransmitter that regulates the levels of two other neurotransmitters, dopamine and serotonin, and also promotes relaxation. (3)
