Quality product
Read a lot of other brands and this one was the best. I’m taking it and it seems to help in the late afternoon when I want to wind down. Zero stomach upset and easy to take.

Helps me relax so I can sleep well.
I have used this product for years. Helps relax me at night and helps me rest well without feeling like I have a hangover in the morning. Recommend using it for a few months then taking a break so your body won't build up a resistance to it.

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.
