The science behind L-Theanine: How this tea compound fights stress without drowsiness
L-theanine, found mainly in green tea, promotes relaxation without drowsiness, enhancing alpha brain waves for relaxed focus.
L-theanine mimics neurotransmitters like GABA and glutamate, fostering “calm alertness” and smoothing caffeine’s jitters when combined.
Key benefits include boosting mental alertness and reaction time (especially with caffeine); reducing stress and anxiety; improving sleep quality; supporting immunity; and regulating blood pressure via nitric oxide production.
Get L-theanine from green tea (20-30 mg/cup) or supplements (100-200 mg); effects can be felt within 30-60 minutes.
L-theanine is generally safe but consult a doctor if pregnant, on medication or managing chronic conditions. It is not a cure-all.
