"My head feels clearer & not as foggy"
"This has changed several things in my life. 1 it works immediate,thats helpful. 2 its benefits are working from a. m until pm. i take it once aday. For calm&focus&clarity. For me iv found its really good for anxiety. Need to drink lotsa water during the say to hydrate!"
"L-Theanine does what it says it does. On the occasional cup of coffee - I will open a capsule & stir it in. Brilliant!"
"Everyone in the family takes this - when they’ve got work worries, exam worries, or just that “woke up with anxiety for no reason” worry. It’s like exhaling after holding your breath."
"Helps quiet my mind!"
"I pour a capsule of this in my morning brew. Takes the jitter out of the ‘Joe’."
"I like theanine to help relax and lately take before bed. Not sure if the sun theanine aspect which makes it more pricey makes it any better. I haven't noticed. Used to. buy Solgar but they're not in stock now."
"I had been experiencing anxiety for some time and on my daughters advice I purchased. I did find that it took couple of weeks for affect but Im happy I persevered and continued to take. Will be purchasing onwards."
"Theanine is a great morning mood booster, and I highly recommend it!"
"Love this stuff! Keeps me relaxed without drowsiness. Great for times of stress or anyone with anxiety. I always buy more."
