What is L-Theanine?Updated 2 years ago

An ingredient in Brain Bright, L-Theanine, an amino acid extracted from exotic tea leaves, is closely related to the neurotransmitter GABA and is easily absorbed by the body. L-theanine has been shown to promote a calm, focused attention and enhance brain power. 

In a peer-reviewed, single-dose, acute, double-blind, placebo-controlled study performed by Dr. Anna C Nobre at Oxford University, 16 healthy subjects demonstrated the ability of a single dose (50mg) of L-theanine to significantly enhance brain power in the Alpha-1 frequency band in healthy human subjects. Activity in the alpha-band is a key component in focused attention processes.
