Great product very solid
It works very well for me, value for the money felt reasonable to me. It did not mess with my stomach or anything like that. I have taken L-Theanine products for years to manage stress and I do like these because they are extended release and seem to last me through the night. Focus wise it calms the overthinking thoughts to where I can focus on what I need to get done. Next time I order some more I’m going to get a bigger bottle.

Great for stress
Great for stress, it really seems to help calm you down. I had no adverse side effects taking it and then taking it for over 60 days. Great product.

calming
Very helpful for everyday undiagnosed and unmanaged anxiety. I take half a capsule during the day when I start feeling overwhelmingly anxious and it helps me a lot.

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.

Very strong and potent... too strong for me but at least it's the real deal!!
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.
