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.

This is the holy grail of supplements!!
L-theanine has been a LIFE SAVER for my caffeine induced anxiety. I have been taken this supplement daily for over a year. Eliminated all of the jitters and anxiety from caffeine. I recently started taking it before bed and it literally knocks me out.

Pretty strong Theanine - helps to wind down before sleep for me
I've tried a few other brands, that were much cheaper, and I think this one is more effective for me. I take it an hour before bed sometimes if I am a bit wound up, and this really helps me to chill out and relax. It's not a magic cure all. It isn't going to knock you out, but it does help calm anxiety before bed.

Feeling great
Me and my husband take this and it makes me feel great! Plenty of mental clarity to get through the day and a nice price. We haven’t noticed any side effects, but it does take a few days to notice a difference.

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.

Works for ME
So I'm assuming you're here to shop for a stress reducing remedy. This is it. To start, I'm 56 and when I started menopause late 40's my anxiety went through the roof. I was consistently nervous and would wrench my hands or had that nervous belly feeling keeping me awake or appearing out of nowhere during the day. I started taking a low dosage Lexapro at night that got me through the night and most days... but that feeling creeps up again from time to time and I didn't want anymore "drugs" or a higher dosage in my system. A friend recommended the Thorne Theanine two years ago and they work! They take off that edge and reduce the stress quickly any time during the day without any drowsiness. If I feel the need, I'll take one at bedtime and sleep absolutely perfect. Told my doctor about taking these and she is good with them! Highly recommend!
