## Overview

Life Extension Optimized Tryptophan Plus delivers 1000mg of high-quality L-tryptophan per serving, enhanced with niacin and L-lysine to support serotonin production for improved sleep, mood, and stress response. This gluten-free, non-GMO, vegetarian supplement promotes restful sleep, healthy stress modulation, and satiety, making it a scientifically formulated ally for your holistic wellness routine.

## Description

Your body requires the essential amino acid tryptophan to produce and maintain healthy serotonin levels. But your body cannot make tryptophan on its own. Our Optimized Tryptophan Plus provides 1,000 mg of high-quality L-tryptophan per serving to encourage a healthy mood, help support optimal sleep, and promote a healthy stress response. By promoting healthy serotonin levels, L-tryptophan also promotes satiety to help support healthy weight management. Hops, L-lysine and niacin are included in this sleep supplement to support healthy tryptophan activity in the body and promote healthy cellular function. This supplement should be taken in conjunction with a healthy diet and regular exercise program. Individual results are not guaranteed, and results may vary.

## 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 your body needs adequate levels of the essential amino acid tryptophan to make it.
- Get some shuteye – Modern lifestyles seem to take rest for granted—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 feeling full. Tryptophan also encourages your body’s healthy response to stress.
- Ingredients matter – We use only the finest raw ingredients with the quality and purity you deserve. The majority of our products are non-GMO, gluten-free and manufactured in the USA—and a Certificate of Analysis is available for every one.
- Live your healthiest life – We believe the answers to a healthier life are within reach, and that scientific research is the key to getting us there. That’s why so many of our formulas feature specific ingredients and amounts based on scientific studies.
- This supplement should be taken in conjunction with a healthy diet and regular exercise program. Individual results are not guaranteed, and results may vary.
