Function & Application

(1) Reduces Stress & Anxiety
Mechanism:

Boosts GABA (gamma-aminobutyric acid), a calming neurotransmitter.
Modulates serotonin and dopamine levels, promoting relaxation.
Evidence:

Clinical studies show 200–400 mg/day reduces stress markers (e.g., lowers cortisol).
(2) Improves Sleep Quality
How It Works:

Does not cause drowsiness directly but eases anxiety and overthinking for better sleep onset.
When combined with caffeine (e.g., in tea/coffee), it counteracts caffeine-induced jitters while enhancing focus.
(3) Enhances Cognitive Performance
Effects:

Increases alpha brain waves (linked to relaxed alertness), improving attention and creativity.
May support long-term brain health (animal studies suggest neuroprotective potential).
