Calm focus without drowsiness — from tea leaves
L-theanine is a natural amino acid found in tea leaves that promotes alpha brain wave activity — a state of calm, focused alertness. It raises levels of GABA, dopamine, and serotonin without any sedative effect, delivering relaxation without fatigue and focus without tension.
The strongest effect is achieved in combination with caffeine at a 2:1 ratio (250 mg L-theanine : 100 mg caffeine), where L-theanine reduces jitteriness and amplifies focus. One 100 g pack contains 400 servings — a bulk supply for everyday use.

Key benefits
- Natural calm without any sedative effect.
- L-theanine raises levels of GABA, serotonin, and dopamine in the brain without causing drowsiness or dependency. The result is a state of calm alertness — relaxed focus reminiscent of meditation.
- Alpha brain waves — focus without tension.
- L-theanine demonstrably increases alpha brain wave activity (8–14 Hz), the state typically associated with meditation and deep rest — the brain works efficiently, but without stress or mental short-circuits.
- Synergy with caffeine at a 2:1 ratio.
- The combination of 200 mg L-theanine with 100 mg caffeine (the synergistically optimal ratio) demonstrably enhances attention and working memory, while L-theanine dampens the jitteriness caused by caffeine.
- Sleep quality support without dependency.
- L-theanine promotes relaxation and restful sleep onset without negatively affecting REM sleep or morning alertness – it has none of the sedating effects of sleeping pills.
