## Overview

Life Extension Theanine XR™ delivers a scientifically formulated, extended-release L-theanine supplement designed to promote a calm, wakeful state throughout the day. Non-GMO, gluten-free, and vegetarian, it supports healthy neurotransmitter balance to reduce stress without drowsiness, crafted with premium ingredients and made in the USA.

## 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.

## Questions & Answers

**Q: What does taking L-theanine do?**
A: Taking L-theanine, a relaxing amino acid found in green tea, can help promote a sense of calm and support a healthy stress response when life gets hectic.

**Q: Is it OK to take L-theanine daily?**

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