Calm, Focused, and Finally at Ease
I’ve been taking Thorne L-Theanine for a while now, and it has made a noticeable difference in my anxiety. Within about 30–45 minutes, I feel calmer and more focused without feeling drowsy. It’s like my brain finally has a “pause button” during stressful moments.I love that L-Theanine helps promote relaxation by supporting alpha-wave production in the brain, and it also boosts GABA, which helps my mind slow down when I’m spiraling. Since I started taking it, I’ve been able to focus better, handle stress more calmly, and my overall mood feels steadier.I also appreciate that Thorne’s supplements are third-party tested—I feel good knowing what’s on the label is actually what I’m taking. This has become a staple in my routine, and I’d recommend it to anyone looking for a natural way to support a healthy stress response.

Surprisingly powerful and incredibly effective
When I first started taking this, I had never tried L-theanine before. I took the full 200 mg dose, and it hit harder than I expected. Not in a bad way, but in a way that made me pause. My brain immediately shifted into a calmer, slower state. It felt like someone flipped a switch from “on” to “rest.” I was honestly shocked by how noticeable the effect was.For about a week, I actually opened the capsules and took only half (around 100 mg), which felt more manageable at the time. Now I take the full 200 mg dose, usually twice a day. It has become a staple in my routine.This completely removes the edge I used to get from caffeine. No more racing heart rate, jitters, shaky hands, or sweaty palms. I can drink coffee and feel alert without the usual overstimulation. My stress feels much more level throughout the day.I’ve been impressed with Thorne in general, but this particular supplement has exceeded my expectations. I did not expect something so simple to make such a clear difference.

Buy this for better sleep!
Between these and some magnesium supplements before bed, I have been sleeping better than I have in my entire life!! This is coming from an insomniac!

Works for me, but a bit pricey…
These are small and easy to swallow, and they do work. I started out at 600mg and definitely felt the effects. After about three days, I’m feeling less groggy, but the lessened anxiety and increased focus are still present. Only downside is the price. I will go through a bottle a month and on top of other vitamins, supplements, etc. it’s going to get pricey.

Useless, doesn’t work for me. Thorne Stress B Complex works better.
