A staple in my house

Love the anti-inflammatory benefits, it’s a staple in my house for low energy, brain fog and pain. Not ideal to take a lot every day for months but great for as needed once you reach a point of relief and improvement in health.

I love that this is a 200mg product, and it works great at calming the mind when you need a little help. Also works great when I take 2 to fall asleep.

Better focus

Posted   by Jessica from Jacksonville, Florida

I have ADHD and I've been trying things to help with my anxiety that I get from my meds. My therapist actually recommended L-theanine, and it does help me feel a little more relaxed. I have also done a little research and learned that these work great with coffee for a boost in focus and not getting the jitters. Just take one capsule with your cup of coffee for a little more focus in the morning.

Not for me

This made me feel horrible. I took a smaller dose than recommended and it made me sick to my stomach to the point of vomiting. I threw it away after one use.
