L-Theanine is an amino acid primarily found in tea leaves, with several key uses:
- Relaxation and stress reduction: Promotes calmness and relaxation without causing drowsiness by increasing levels of GABA, dopamine, and serotonin.
- Cognitive function: Enhances focus, mental clarity, and attention, especially when combined with caffeine, by promoting a state of alert relaxation.
- Anxiety relief: Often used to reduce feelings of anxiety and promote a calm state of mind.
- Sleep quality: May improve sleep by reducing stress and promoting relaxation, helping users fall asleep more easily.
L-Theanine is commonly found in stress-relief, nootropic, and sleep support supplements.
