## Overview

Life Extension L-Tryptophan 500 mg capsules provide a potent, scientifically-backed dose of this essential amino acid to support serotonin production, promoting restful sleep, balanced mood, and healthy stress response.

## Description

Serotonin is a neurotransmitter in the brain associated with positive moods and restful sleep. To produce and maintain optimum serotonin levels, your body requires tryptophan, an essential amino acid the body can’t produce. Life extension offers L-Tryptophan capsules to broadly and powerfully support tryptophan levels already within the normal range.

Review: Wonderful for a good night's sleep

## Features

- SUPPORT YOUR SEROTONIN LEVELS – You’ve probably heard of serotonin. It’s a neurotransmitter that is deeply involved in both restful sleep and positive mood. But what you might not know is that your body needs adequate levels of the essential amino acid tryptophan to make it.
- GET SOME SHUTEYE – Modern lifestyles seem to revolve around not getting enough rest—but that’s not healthy. To keep your body healthy, you have to let it rest. L-Tryptophan encourages serotonin production, which in turn promotes restful, restorative sleep patterns.
- MOOD (AND MUNCHIES) – What else is tryptophan good for? Well, it promotes a healthy mood (that’s the serotonin again) and it also promotes satiety: the sensation of being full. Tryptophan also encourages your body’s healthy response to stress.
- INGREDIENTS MATTER - Sourced using only the finest raw ingredients with the purity and potency your body deserves. This product is certified non-GMO and gluten-free. Manufactured in the USA and a Certificate of Analysis is available for every product we produce.
- LIVE YOUR HEALTHIEST LIFE - For over 40 years, we’ve been developing advanced, effective formulas made with the highest standards and based on the latest scientific findings. We believe the answers to a healthier, richer life are within reach and that rigorous scientific research is the path to get us there. Or formulations are created using the exact ingredients and dosages used in the studies that inspired them, ensuring that maximum bioavailability and efficacy is achieved.
