For the occasional anxiety.
These help so much for when I have something big planned that I know would cause me anxiety. They kick in within 30-45 mins and they give this calm. I don't get dizzy or tired, just a feeling like my anxiety was knocked down a notch or two. It doesn't completely eliminate it, but it makes it manageable. Super easy to swallow they are very small pills, no weird texture, taste or smell. No other weird side effects, that I've experienced. Pretty good quality.

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!

Worked for daytime relaxation, but kept me awake at night
For daytime relaxation and focus is OK, but since these supplements are very personally aligned to your own physiology, your effects will vary. As side effects, these keep me alert at night and affects my sleep quality greatly.

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.

Reliable Brand, Soft Results
High‑quality supplement that helps support relaxation and calm focus. The effects are gentle rather than strong, and it’s a bit pricey, but overall a solid and reliable product

I feel more at ease taking this product. I paid $68 here on Amazon. I won't be buying it again because the regular price for the same product at Costco is $29.
