High-quality supplement that helps promote calm focus
I’ve been very happy with this L-Theanine from NOW Foods. The capsules are easy to swallow, and I appreciate the simple, clean ingredients from a brand I trust. It helps promote a sense of calm and focus without making me feel drowsy or sluggish. Great option for daily use, especially during busy or stressful days. I would definitely repurchase.

Just try it
Just Try It I don’t normally write reviews, nor is this sponsored in any way. I struggle with sleep. My mind doesn’t like to shutoff from the day and continues to race thinking about earlier or what I need to accomplish tomorrow. This combined with the calm app sleep meditations has given me the deepest week of sleep I feel like I’ve had in years WITHOUT being groggy the next morning. I’ve tried prescriptions from my doctor (hydroxine) and other variants of melatonin. They would give me a deep sleep, but I would feel like I was on a bender the night before. This doesn’t hit you all at once, it’s more like a gradual relaxation and in the morning I feel refreshed for a change. I’d say it’s worth the try for you. Everyone’s body is different so your mileage may vary. Make sure your caffeine intake is down, exercise, relaxed nightly routine are all a part of your sleep strategy. This isn’t a miracle worker, but feels like the missing piece for me. Note: This is after 1 week of daily use while also doing the above. One thing I hope is that it continues long term, even still I’m happy with the price for the week of amazing sleep I’ve gotten

Sleep savior
Can be tough to get down is the only reason I’m giving 4 stars.. otherwise I have had no abdominal discomfort or G.I. discomfort. And it honestly works like a charm. I now sleep through the night with very rare occasions waking up at my typical 3 AM. I experienced no grogginess the next day..

Helps you relax to get a better sleep!
Wow! It really helps me to relax along with the now magnesium. I have been having problems getting sleep because of my thyroid is out of wack. I have also adjusted my thyroid medication too. But it just really seems to help me relax.

Completely takes away the jittery nervous energy from too much caffeine
A favorite of mine. Anytime i have to much caffiene (maybe a strong coffee or from soda) and it gives me that nervous jittery energy 😬 I take 2 of these, that nervous energy calms down and completely stops the jittery feeling and Im left with a more relaxed calm feeling, but with energy that i can actually focus onto something (or things) Also take this before bed to help me get sleepy (calm relaxed feeling) especially if I've been go go go all day, and need that bit that says "ok you can relax now" White filled caspsule that is small and easy to take, no taste. High quality, I've never had this L-theanine not give me a calm relaxed feeling.

If you’re feeling blue this is for you!
Big time game change! I deal with winter blues and this pulls me up right out of my funk. Takes the edge off the anxiety and depression, calms the nerves and puts me in a good mood almost immediately. I trust the NOW brand & have never been disappointed with the effectiveness of their supplements!

It REALLY Helps With Sleep
DISCLAIMER: I am NOT a medical doctor or a physician. I am NOT encouraging anyone to quit taking any medication whether it's prescribed or not. I am simply giving my personal OPINIONS and sharing my story. I started a new job over a month ago where instead of working evenings (around 6 PM), I'd start at 7 in the morning. It really messed with my biological clock since I was used to sleeping later (usu. well past midnight). I had insomnia for almost a week since I had a hard time just to fall asleep. After doing some research, I found out about L-theanine. Out of desperation, I ordered this, selected the fastest shipping option, and took it later that night about an hour or two before my (new) bedtime. Wow, this stuff works much better than I expected. Not only did I get knocked out, but I fell asleep MUCH faster, STAYED asleep, and the quality of my sleep improved. Ever since, I am happy to say that as of now (June 6th, 2025), I have been consistently getting at least of 7 hrs of rock solid, uninterrupted sleep. I haven't experienced any negative side effects from taking this. This makes it a great alternative to the drugs out there that promise to deliver what this amino acid does (at least for me). In addition to sleep benefits, I've noticed a slight decrease in my social anxiety and I don't get as jittery as I used to when enjoying anything with caffeine in it. If you're in the same situation that I was, I would give this a try.

2つ購入しました。 集中力を高める本を読んでいるとテアニンとカフェインのセットで更に高まるとのことと夜に飲むとリラックスし疲れがとれるメリットがあるとのことで実験的に導入しました。 約1ヶ月ほど使用しました。 集中力の方に関しては機会は少なかったので、よくわかっていません。 夜寝る前に飲むと確かに寝に落ちる時間は早まったように感じます。 朝も目覚めもよい。 寝に落ちる感覚はメラトニンサプリの方が早いがメラトニンは寝起のだるさが残るので、その点に関してはこちらの方が使いやすい。 早くお寝付きたい場合はメラトニンでゆったり寝に落ちたい際はテアニンと使い分けると良いと感じた。
