L-Theanine is a natural phytochemical found in Japanese green tea. It is a non-essential amino acid present in the brain and a close relative of glutamate. Research suggests that L-Theanine interacts with GABA (Gamma-Aminobutyric Acid) receptors in the brain, which are associated with relaxation and nervous system function.*
L-Theanine is found almost exclusively in the green tea plant (Camellia sinensis) and is the primary ingredient contributing to the unique taste of green tea. Studies have shown that L-Theanine crosses the blood-brain barrier and may support dopamine and GABA activity in the brain. Human studies have shown that L-Theanine supplementation is associated with the emission of alpha brain waves, which are linked to a relaxed, alert state.*
L-Theanine may support relaxation without causing drowsiness, as measured by increased generation of alpha-waves. It may also support learning and mood by influencing dopamine and serotonin neurotransmitter activity in the brain.*
L-Theanine helps promote a restful, relaxed state while supporting daytime alertness.*
