Best L-Theanine for Relaxation
This is the best L-Theanine I’ve tried. It really helps relax me, especially at night. I take it with magnesium before bed and it makes me feel calm, sleepy, and ready to unwind. I’ve tried other brands, but this one works the best and feels the most consistent. It’s gentle on my stomach and helps me settle down after long, stressful days. Definitely my favorite.

100% Recommend
Obsessed with this. If I eat late at night I have the craziest dreams or if I’m anxious I’ll be up all night with crazy dreams constantly waking up. Take these before bed and I have the best sleep I’ve ever had. Calms the mind, don’t feel drowsy after. Definitely recommend for any sleeping troubles. Helps you fall asleep and stay asleep.

Everyone is different !
I do not take all of a new supplement if there is any way to reduce the dosage, especially if ppl are reporting any adverse side effects. I’ve been emptying at least half of the capsule out before taking right before bed. It’s definitely helping me sleep through the night so that has been great but I have also noticed a tiny bit of nausea as well as a groggy feeling in the morning. Trying to decide if I’m going to keep taking Tri Magnesium or not. And hoping I’ll be able to take the whole capsule eventually. It’s definitely strong!

Easy to take and helps take the edge off
These L-Theanine capsules are simple to take and feel really gentle. I notice a slight calming effect, nothing heavy, just enough to take the edge off when I am feeling stressed. No weird aftertaste and no drowsiness. It is always hard to measure supplements exactly, but this one feels clean and consistent. A nice add-on if you want a little extr
