Take l-theanine to improve focus

Description

Reduce anxiety & stress instantly with L-Theanine - the amino acid that is clinically proven to promote calm focus without drowsiness.

Why we recommend this

  • L-Theanine increases alpha brain wave activity, promoting a state of "alert relaxation" similar to meditation, as demonstrated in EEG studies published in the Asia Pacific Journal of Clinical Nutrition
  • Dr. Rhonda Patrick explains that L-Theanine crosses the blood-brain barrier within 30 minutes and increases GABA, serotonin, and dopamine - neurotransmitters that regulate mood, alertness, and sleep
  • Clinical trials published in the Journal of Clinical Psychiatry found L-Theanine reduced anxiety symptoms in patients with schizophrenia and schizoaffective disorder
  • Research in Biological Psychology shows L-Theanine (200mg) reduces physiological stress responses and subjective stress ratings during cognitive tasks
  • When combined with caffeine, studies show L-Theanine preserves caffeine's cognitive benefits while reducing jitteriness and blood pressure spikes

Usage

200-400mg as a single dose for acute effects; 100-200mg twice daily for ongoing support

Timing

Morning with or without caffeine for focused calm; 30-60 minutes before bed for sleep support; or as needed during high-stress periods

Important notes

  • Dr. Peter Attia suggests monitoring anxiety levels as approximately 5% of individuals may experience paradoxical reactions including increased alertness
  • L-Theanine appears safe at doses up to 900mg daily, but start with lower doses to assess individual response
  • Avoid if using sedative medications unless advised by a doctor, as it may enhance sedative effects
  • While generally well-tolerated, discontinue if you experience headaches, dizziness, or gastrointestinal discomfort
  • Those with low blood pressure should monitor their response, as L-Theanine may modestly reduce blood pressure
