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.

Other Ingredients

Dibasic calcium phosphate, stearic acid, modified cellulose gum, and silica .

All around GREAT!

Posted by Reviewer1972894 on Nov 02, 2016

This helps curb a low mood swing with 1-2 tablets. To help fall asleep 2-3 tablets, repeat if waking up again midway through the night. This has replaced my antidepressants and no side effects! So wonderful!

Worked better than medication for me

Posted by SharonChua on Oct 29, 2016

I had been on and off Prozac and lose dose xanax for several years, and they have lost much of their effectiveness for me. L-tryptophan had an immediate effect the very first night I took it, and has continued to work for about a month now. I take 3 pills nightly on a relatively empty stomach. Very grateful for these because I had suffered from terrible sleep for several months prior. I was achy, exhausted and bad-tempered because of it. Now sleep has completely normalized and I can feel that it's deep, restorative sleep. I'm groggy in the morning but a cup of coffee takes it away immediately. I pray this continues to work, am quite amazed actually that a natural supplement has this strong an effect.

Fantastic

These tablets are fantastic if you are having trouble sleeping. I recently lost my son and couldn't sleep but these made me relax and had a great sleep with no after effects, highly recommend them.
