L-theanine, an amino acid found in green tea, can support relaxation. This compound supports a healthy response to stress to maintain a sense of zen and stay calm and collected all day long. L-theanine does this by supporting the activity of glutamate, an excitatory neurotransmitter, while also promoting healthy levels of GABA, a calming neurotransmitter. When these neurotransmitters work together, they can help support relaxation. Since the body metabolizes L-theanine quickly, this formula includes extended-release technology for benefits both immediately and over time. Vegetarian, non-GMO, gluten-free and manufactured in the USA.

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.

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.

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.

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.
