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.

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!

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.
