Product Overview

Description
  • Dietary Supplement
  • Mood, Relaxation, Sleep

The essential amino acid L-tryptophan helps support relaxation, restful sleep, and feeling better. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response. L-Tryptophan also supports immune functions because it is the body's precursor to the kynurenines that regulate immunity. If needed, L-tryptophan converts to niacin in the body, which supports circulation, a healthy nervous system, the metabolism of food, and the production of hydrochloric acid for the digestive system. Source Naturals L-Tryptophan is extremely pure and is regularly tested to ensure the highest standards of quality.

Suggested Use

1 tablet three times daily, between meals and preferably with fruit juice. To support restful sleep, take 3 tablets before bed.

Other Ingredients

Dibasic calcium phosphate, stearic acid, modified cellulose gum, and colloidal silicon dioxide.

Tryptophan by Source Naturals

Posted by Reviewer2809978 on Jun 25, 2009

A night's sleep without L-Tryptophan isn't a Good night's sleep. I'm 58 and have been getting a normal night's sleep for about five years now, since I started supplementing with tryptophan. One 500mg tablet when I'm ready to fall asleep is all I need (actually I take about 0.25mg melatonin along with it[and sleep like a baby])

good night's sleep

Posted by Reviewer1588649 on May 06, 2010

I am at that age where it is often difficult to get a good night's sleep. However, if I take one capsule of L-Tryptophan, along with Melatonin, I can get the rest I need.

Most sleep products haven't worked for me, but this product combined with Source Naturals NightRest with Melatonin has helped me.
