## Overview

Life Extension Theanine XR™ delivers a scientifically formulated, extended-release L-theanine supplement designed to promote a calm, wakeful state throughout your busy day. Non-GMO, gluten-free, and vegetarian, this USA-made formula supports healthy neurotransmitter balance to help manage stress without drowsiness, ensuring you stay focused and collected from start to finish.

## 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?**
A: Taking L-theanine daily is generally recognized as safe, so it can be taken daily as needed. But you should always check the label on any supplement for proper usage instructions.

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

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.
