L-Theanine
Promotes alpha brain wave activity - the neurological signature of calm alertness without sedation. Works synergistically with the 66mg natural caffeine from matcha for smooth, sustained energy with no crash.
Mechanism
L-theanine is an amino acid found almost exclusively in tea (Camellia sinensis). It readily crosses the blood-brain barrier and modulates inhibitory neurotransmitter activity, increasing alpha brain wave (8-12 Hz) power - the EEG signature of relaxed, focused alertness.
The theanine-caffeine combination is among the most well-studied cognitive stacks. Theanine attenuates the anxiety-inducing and blood pressure-raising effects of caffeine while preserving its alertness and attention-enhancing properties. This formula contains both: 200mg Suntheanine plus ~66mg natural caffeine from matcha, with ~40mg additional theanine co-occurring in the matcha itself.
Key Benefits

- Co-occurs naturally with caffeine in Camellia sinensis and has been studied in combination
- Synergistic with caffeine for sustained attention
- No sedation at standard doses
- Suntheanine: chirally pure L-isomer with highest bioavailability
The Research
