What is Theanine?



L-theanine is an amino acid found naturally in green tea but otherwise not found in many foods.  Historically, L-theanine has been shown to promote relaxation by interacting with the nervous system in a positive manner. Preliminary research indicates that it can act as an antagonist to the hyperactivity effects of caffeine, help decrease anxiety and enhance the immune system. The research suggests it may do this by increasing the level of GABA (gamma-amino-butyric acid), an important inhibitory neurotransmitter with mood-enhancing effects.
