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.

This Thorne Theanine gives me a calm focus during the day!
I love this Thorne Theanine for the day time! I take it morning / mid-morning and it definitely helps my mind feel more alert and focused. I can feel the good difference when it kicks in - takes about 30-45 minutes to take effect. I know some people take Theanine for sleep, but for me, this Thorne one really gives me a focused energy during the day. I sometimes take a 2nd capsule around mid-afternoon. I love it so much, that I am on my 3rd bottle. It has also helped my overall mental health. Honestly, I was struggling with anxiety for years due to some outside circumstances. I had been taking mental health meds/anxiety meds. I started having heart problems and needed to stop the mental health meds. I switched to natural supplements like this Thorne Theanine, Vitamins B1 in high dose, Vitamins D3 & K2, and cut out social media. My anxiety is non-existent, and I feel a peaceful calm that I never felt before in my life. I’m so grateful I was able to stop the meds. Cannot recommend this enough! No side effects, easy on the stomach. I love Thorne products and this one is very effective for me!
