Life Extension L-Tryptophan 500 mg – L-Tryptophan Supplement for Healthy Sleep and Stress Response Support – Gluten-Free, Non-GMO, Vegetarian – 90 Capsules

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.

• 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.
