    Product Overview


    • Helps Reduce Anxiety
    • Dietary Supplement

    L-Theanine is a unique amino acid found almost exclusively in the tea plant (Camellia sinensis) and is the primary ingredient contributing to the unusual taste of green tea. Animal studies have shown that L-theanine crosses the blood brain barrier, increases dopamine and GABA levels in the brain and inhibits the stimulatory properties of caffeine. Human studies have shown that taking L-theanine results in the emission of brain waves associated with a state of relaxation.

    Suggested Use

    1 capsule 1 to 2 times daily with a glass of water.

    Microcrystalline cellulose, gelatin (capsule), colloidal silicon dioxide and magnesium stearate.

    Great for anxiety and depression!

    Posted by iHerb Customer on Jul 25, 2017 | Verified Purchase

    I've been taking 2 of these a night for almost a year and swear by them for the relief of anxiety and depression. They don't make me feel drowsy or hyperactive, they just gently make me feel better. It can take a week or two for them to take full effect. I haven't noticed any side effects and don't see myself ever stopping them unless I have to. I take them along with 2 x L-Tryptophan, also from source naturals.

    Thanks for your feedback!
