Source Naturals L-Theanine -- 200 mg - 60 Capsules

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.

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."
