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 in the brain. GABA is an inhibitory neurotransmitter and its natural release in the body can lead to relaxation. Supplementation with L-Theanine can help maintain GABA levels, and research indicates it can promote a calm, relaxed state without causing drowsiness.
