Product Overview

Description
  • Dietary Supplement
  • Mood, Relaxation, Sleep
  • Non-GMO Validated

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.

This product has changed my life!

Posted by 4877369431605964149 on Aug 31, 2012

For as long as I can remember, I have suffered from anxiety that brought me to a depressive state and panic attacks..terrible way to live. This illness runs in my family and came from my father. I also had my dear brother take his own life 20 years ago because he could not take it anymore.. and he never got the help that he needed. Through the years, I have been on Paxil, Prozac, Celexa, Colonzepam...you name it. Upon my last visit to a dr. that cost me $150, he told me that I had a low serotonin level and I needed 'professional help'. Out of pure desperation, I went on the net and started learning everything I could about this illness...which brought me to this site and that a little pill 2-3 times a day is all I needed. I went to a local healh food store and found this same product..just to try it. IT WORKED! I trashed my Celexa. I did find this site and it is much cheaper to buy and I ordered 120 of them and will continue to order. I have told 2 friends that suffer the same and they are trying it, too. No more sleepless nights, no side affects NO MORE ANXIETY and I have a complete and full life, finally. THANKS iHerb!

good product to induce sleep

Posted by Reviewer2669925 on Jan 23, 2008

Taken along with vit. B6 at bedtime helps to stay asleep all night. I cut the 500mg. tab in half, with 25mg. of B6.

Really helped with sleep!

Posted by Reviewer2991146 on Apr 22, 2009

I purchased L-Tryptophan 500mg to help with sleep. I've been taking Ambien for years and would like to eventually come off of it completely. I started taking 3 L-Tryptophan pills, about 30 min before bed, with a B complex vitamin. It took 4 or 5 days for me to start noticing a difference with my sleep. I fall asleep easily and I have been feeling much more rested when I wake up in the morning. I remember my dreams more often now too. I have even stepped down my Ambien dosage to half a pill and plan to be off it it in 2 weeks. The L-Tryptophan really has helped me, and I've had difficulty sleeping for as long as I can remember. I feel great knowing this is a natural product. I am thrilled that I won't be Ambien-dependent within a few weeks!

L-Tryptophan

Posted by Reviewer3091225 on Feb 24, 2008

I have have been using this product for approx. 1 1/2 yrs. I have tried other brands of L-Tryptophan and I think this is the best. You also offer it at the best price around. Thank you.

A Trusted Suppliment and Brand Name

Posted by Reviewer2189659 on Sep 27, 2008

My father, a Chiropractor, always had us use L-tryptophan during high stress events,ie. weddings, etc. It made such a huge difference-with no side affects. Then it was banned...... My health food store tells me it's still banned and they don't carry any! I was delighted to find several brands to choose from at iherb and Source Naturals has been my choice with many suppliments in the past.
