What is L-Theanine?

L-Theanine is an amino acid found naturally in tea leaves (Camellia sinensis). It promotes relaxation without drowsiness by increasing alpha brain wave activity and modulating GABA neurotransmitter levels. Clinical studies show effective doses range from 200-400mg daily, with calming effects beginning within 30-60 minutes.

  • EFFECTIVE DOSE

How Does L-Theanine Create Calm Focus?

Your stress response works like this:

1. L-Theanine crosses the blood-brain barrier (30-60 min)
2. Increases alpha brain wave activity
3. Boosts GABA (calming neurotransmitter)
4. Modulates glutamate (excitatory neurotransmitter)

Alpha waves = the "calm but alert" state.
Not sedation. Not drowsiness. Focused relaxation.

L-Theanine also supports serotonin, dopamine, and healthy stress response.*
