What I didn't know
Let me warn you if you work overnight you may wanna wait until you get home before taking. I wasn't sleepy at all. Just felt tightness in my shoulder & felt like I needed to relax. I popped one of the stress tabs & immediately I could feel the shift in my body for the better next I was waking up. Put me to sleep so fast. It's money well spent.

Amazing
Wow. I have very bad social anxiety at times. These pills really help to take the edge off. Going to pair with mag glycinate and see how well it does for my anxiety. Definitely recommend!

Helpful for Anxiety
I started taking this a few months ago—one in the AM and I think it’s helped me stay a bit more calm through the day. It’s the only extended release I’ve found that seems to work. I’ve had zero side effects.

Will help if you have anxt
If you suffer from anxiety, this product will definitely help you. On days that I feel extra overwhelmed. I take one in the morning and one at night. I also take with ashwagandha, life changer! It's easy to swallow and very effective.

Why did you choose this product over others?: This is a high quality and strong dose of L-theanine. The dose is far too strong and potent for me but some people might find that to be a good thing. It is very sedating. If I use it I need to break it in half. It's so strong that I don't use it very often but it's good to have on hand just in case.
