## Overview

Life Extension Theanine XR™ delivers a scientifically formulated, extended-release L-Theanine supplement designed to promote a calm, focused mind throughout the day. Non-GMO, gluten-free, and vegetarian, it supports healthy neurotransmitter balance for stress management without sedation, making it ideal for professionals seeking sustained mental clarity and relaxation.

## Description

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.

Review: Can’t live without! Excellent for histamine sensitivity - I only use life extension. I have autoimmune issues. Gut issues from it. Great for histamine resistance , gut and inflammation in the gut. Not about the energy . Excellent for acid reflux, gerd on histamine related food and wine. No side effects . Easy to swallow .
Review: 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.

**Q: When should I take L-theanine for stress?**
