L-Theanine is an amino acid which is commonly found in green tea. It plays a key role in mood support by helping to improve GABA (gamma aminobutyric acid) levels. GABA is an inhibitory neurotransmitter important for nervous system function. Supplementation with L-Theanine can help maintain GABA levels, and promote a calm, relaxed mood.
