Calmer, Clearer, Worth the Upgrade
I’ve been using L-Theanine for months and have noticed a real improvement in my calmness and ability to manage stress. It helps smooth out anxiety without making me feel sleepy. I switched to Pure Encapsulations because I trust the brand’s quality and potency. It is more expensive, but if it fits your budget, I believe it’s worth it for the reliability and results.

Really helped falling asleep and with “hangziety”
Gentle sleep med and if you get coffee jitters or post -drinking jitters (“hangziety”), works for that too. For me, it works for both. Takes about 45 min to kick in and lasts about 4 hours. Supposedly, it takes a month to build up but I didn’t notice that for immediate use or long-term use. Just my personal experience. I will say that taking 2+ pills doesn’t enhance effects for me, at all.

Calming Support and Better Sleep — A Game Changer for My Anxiety
I started taking Pure Encapsulations L-Theanine to help with my anxiety, and I’m so glad I did. Within the first week, I noticed a big difference — my mind felt calmer, I was less tense throughout the day, and I could handle stressful situations without feeling overwhelmed. One of the best benefits has been how much it’s improved my sleep. I fall asleep easier and wake up feeling more rested and refreshed. It’s gentle, effective, and doesn’t make me feel drowsy or sluggish. This supplement has truly been a game changer for my mental well-being. I highly recommend it to anyone looking for natural support with anxiety and better quality rest.

I was a little confused when L-Theanine was recommended as part of my regimen
Never heard of this before, but I thank my naturopath for the introduction! I was a little confused when L-Theanine was recommended as part of my regimen. After all, some internet sleuthing told me it was mainly for help with sleep. And in that arena, I was doing fine: I easily fell asleep, and slept until morning. However, when I read all the other reviews here on Amazon, I found it seemed to be helping people in other areas, including anxiety, OCD behaviors, depression, and even PTSD. Some moms noticed a different in the children's behavior....for the better. With praise like that, I was excited to try it out. My naturopath recommended the dosage of two pills (400 mg total) two hours before bedtime. (It does seem to take a while to work, so that is a good directive.) What I noticed was my sleep, although decent in the past, seemed to be more deep and restful. Be ready for vivid dreams! At least that has been my experience, and it was confirmed by my doctor on my next visit that yes, that is a common experience. This also works for the daytime! As many other reviewers said, it calms without leaving you groggy. I don't have issues with anxiety, but I did notice that when I took one pill (200 mg) in the morning, I was able to stay on task with focus more than usual. Can anyone complain about that??? So, what IS L-Theanine, anyway? It's an amino acid in green tea. Supposedly, some researchers delved into why green tea had so many beneficial properties, and they were able to isolate the amino L-Theanine as one of the main contributors. Once isolated, they produced it in a more concentrated amount in pill form. If you are on the fence about this product, I recommend reading all the reviews...L-Theanine seems to be helpful in such variety of areas, I imagine this to be a beneficial supplement for anyone's health.
