Found in green tea and in every pack of 2THIRTY, L-Theanine promotes calm focus without drowsiness. Here's the science.

What is L-Theanine?

L-Theanine is an amino acid found naturally in green tea leaves. It's unique because it promotes relaxation without causing drowsiness — giving you calm, focused energy.

How It Works

L-Theanine increases levels of GABA, serotonin, and dopamine in the brain — neurotransmitters that regulate mood, focus, and relaxation. It also promotes alpha brain waves, which are associated with a state of "wakeful relaxation."

Benefits for Stress & Anxiety

Research has shown L-Theanine can:

  • Reduce stress and anxiety without sedation
  • Improve focus and attention — great for work or studying
  • Enhance sleep quality when taken in the evening
  • Counteract the jitteriness of caffeine
