Description
L-theanine in tea promotes relaxation without sedation by increasing alpha brain wave activity, reducing cortisol levels, and modulating GABA and serotonin neurotransmission. Clinical studies show L-theanine at tea-relevant doses (50-200mg) significantly reduces subjective stress and anxiety. GABA-enriched teas provide additional calming effects. The ritualistic aspect of tea preparation (especially in Japanese and Chinese ceremonies) adds a mindfulness component that further reduces perceived stress.
