Game Changer for My Sleep Quality!
This has been a game changer for my sleep routine. I take it about an hour before I want to fall asleep (along with some other supplements) and it has done absolute wonders for my sleep quality! For reference I am middle age and dealing with middle age things, but this little supplement has been so effective in helping me sleep. Which, of course, increases quality of life!

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.

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