Life Extension Theanine XR™ Stress Relief – L-Theanine – Promotes a Calm Response to Daytime Stress – Non-GMO, Gluten-Free, Vegetarian – 30 Tablets

I could such a difference in my happiness once I started popping one of these theanines every morning upon waking. They keep me in a good mood all day and help with an afternoon nap if I can fit one in, so happy a friend in Australia suggested them when she was grieving. I’ll never be without them, you won’t be disappointed

Works just as you would think. It relaxes me and the effect seems to last for maybe 6 hours or so. I take before sleep and it is really good.

I've always appreciated LE products. And as expected it works for me. Nice price for such a quality product. I experienced improvement in my sleep.

Very potent theanine. So potent it made me fall asleep. If you’re not prone to sleepiness with theanine (I am), I think you will really like this product.

If taken by direction starts working within a couple of days. It has really worked

Did not work at all I felt nothing. Makes me wonder if I even got the actual product.
