Calm clarity, without sedation

L-Theanine is a naturally occurring amino acid found in green tea (Camellia sinensis), known for its unique ability to promote relaxed alertness. Unlike sedatives, it gently smooths stress responses while supporting focus, attention, and healthy sleep cycles.

May Assist With

Calm, focused alertness without drowsiness
Smoother task switching and mental clarity
Stress and anxious arousal relief
Better sleep onset and deeper rest, especially after demanding days
Improved accuracy and reaction time on cognitive tasks
Adaptation to jet lag, shift work, or sleep loss recovery
Mild blood pressure support (individual response varies)

How It Works

Glutamate ↔ GABA Balance: Calms excess stimulation while supporting steady focus.
Alpha-wave Activity: Encourages relaxed, attentive brain states.
Stress Axis Modulation: Softens cortisol and adrenaline spikes, improving resilience.
With Caffeine: Creates smooth, jitter-free energy for mental performance.
Sleep Support: Helps unwind and restore balance before bedtime.

Dosage & Use

Daytime focus: 200–400 mg, 30–60 min before deep work.
With caffeine: Pair ~2:1 ratio (e.g., 200 mg L-Theanine + 100 mg caffeine).
Evening & sleep: 500 mg, 60–90 min before bed.
Sleep-loss recovery: Morning pairing with caffeine for vigilance; evening dose for rebound sleep.

Each capsule delivers 500 mg pure L-Theanine (L-form)—a higher dose suited for acute stress, evening wind-down, and post-sleep-loss recovery.
