Source Naturals L-Theanine Description

  • Serene Science
  • Focused Relaxation

L-Theanine is a unique amino acid found almost exclusively in the tea plant (Camellia sinensis) and contributes to the unusual taste of green tea. Human studies have shown that taking L-theanine affects the emission of alpha waves in the brain associated with states of relaxation and focused attention. Preliminary research has shown that L-theanine crosses the blood brain barrier, and suggests that it may support healthy neurotransmitter levels in the brain, and inhibit the stimulatory properties of caffeine.


Suggested Use: 1 capsule 1 to 2 times daily.

Energy and a sense of calm I use this each morning and feel calmer and yet more energetic since I started taking it, over a year ago. Recommended to me by bro-in-law who is a doctor. My doctor is fine with my taking it. Will continue to use it and have recommended it to others as well. August 24, 2010
