Product Overview

Description

  • Mood, Relaxation, Sleep
  • Dietary Supplement

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

1/4 teaspoon three times daily, between meals and preferably with fruit juice. To support restful sleep, take 3/4 teaspoon before bed.

Other Ingredients

Suitable for vegetarians and Hypoallergenic: contains no yeast, dairy, egg, gluten, corn, soy or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.

Take with Gaba

Posted by Reviewer1385103 on Oct 10, 2012 | Verified Purchase

I take a dose of this and a dose of Gaba for an excellent nights sleep. I have given this to habitual insomnacs and they have slept through the night for the first time in years.

Dangerous Product

Posted by Reviewer1963609 on Jan 27, 2012 | Verified Purchase

Do not touch these, or anything Source Naturals for that matter - I have been very ill for 15 months after taking two Source Naturals L-Tryptophan capsules. I have all the symptoms of EMS, a serious disease caused by contaminated L-Tryptophan. Several more people in the States are also ill after consuming L-Tryptophan. The bottle states that Source Naturals L-Tryptophan is extremely pure and regularly tested - absolute rubbish, the truth is that Source Naturals buy in bulk the cheapest L-Tryptophan from China. Source Naturals were litigated in the 1980s as suppliers of contaminated Tryptophan which caused an outbreak of EMS, they are back again putting into capsules the poorest quality cheapest junk they can get their hands on to make the biggest profits at the potential expense of public health. Do the world a favour and never buy anything with the Source Naturals label on the bottle.

...if you want to be able to measure doses more precisely than what comes in capsules.

Amazing results

Posted by Reviewer1814780 on May 22, 2010 | Verified Purchase

This review is for L-Tryptophan, and this brand works great. I have not tried any other brand, however. We use 1/4 tsp, 3 times/day, (per Dr. Daniel Amen), and it has significantly reduced everyday stress and anxiety. We just take things more in stride. We tried 5-HTP first, but this works much better for us.
