I have previously used Theanine from NOW Foods, and it worked wonderfully for sleep; I had very vivid dreams and felt well-rested. Unfortunately, this product from GB does not seem to have any effect.

    It is important to note that I have always been an anxious person, but recently my anxiety has reached its peak. It took me some time to realize that caffeine has a very negative effect on my nervous system, which made me feel even worse. I also experienced physical symptoms. I take Ashwagandha together with lemon balm tea, and I no longer consume any caffeine at all. I take 2–3 tablets of each daily, and I can feel the effects very clearly. I haven't felt this relaxed in a long time, and I am now able to pay much better attention to people, which is extremely important to me. Fortunately, the package arrived within 2 days. I have only been following this regimen for one week, but it has cleared my mind, which is essential, as it allows me to restore my mental well-being. Next time, I will also order L-tryptophan along with it.

    I have already tried various supplements for anxiety and panic, but almost all of them made me feel as if I had over-caffeinated myself. Unfortunately, coffee has also increasingly taken its toll on me. Every substance I tried had some unpleasant side effect. The only ones that produced a truly wonderful effect were the amino acid Glycine and the Magnesium-Glycinate formula; both are calming, pleasant, and free of side effects! I had long been considering Theanine, but my previous failures held me back. It was a pity, as one capsule works like a sedative without knocking you out! I began experimenting with how long it takes to take effect, what happens if I take it with coffee, or alone in the morning or evening! If you use it with coffee, it reduces the anxiety-inducing effects of caffeine on the nerves. If used alone, it provides pleasant relaxation. My stomach has not become sensitive, I do not feel drowsy, and it works very effectively on anxiety. I sleep more deeply and wake up fresher. I believe it takes effect within one hour. I now take 100 mg three times daily, and I intend to maintain this regimen! I am very satisfied with both the quality and the product! Thank you.

    I take it for generalized anxiety and panic disorder, as an alternative to Xanax 0.5 SR. I take one tablet in the morning, along with Rhodiola Rosea, L-theanine, and GABA. I can only recommend it; there are no side effects, only beneficial properties!

    I take it 30 minutes before coffee and around 5 PM in the afternoon. It helps me reduce the side effects of caffeine, as I do not experience a severe energy crash two hours after drinking coffee. I also take it in the afternoon to balance stress after work.

    When you wish to build muscle, you must also pay some attention to stress in the body. L-theanine has helped me enormously with "relaxation." Where there is relaxation, there is room for improving testosterone in the body, which leads easily and surely to greater muscle gains! Brilliant L-theanine.

    I take 1 tablet (even though it says 2 tablets). Every morning after waking up, 90 minutes after caffeine... increased energy, concentration, and motivation. Combined with Tongkat, it provides a superhuman boost. I will definitely order more.
