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. (These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.) Hypoallergenic: Contains no yeast, dairy, egg, starch, salt, preservatives, or artificial color, flavor or fragrance.

  • Essential amino acid that helps support mood, relaxation, and restful sleep

5Sleeping better AND feeling better!  Jan 28, 2012
By Kristen Stemple
I love this supplement so much because it not only helps with my insomnia (life-long insomniac here!), but it also has a noticeable affect on my anxiety levels. I've never been diagnosed with any type of anxiety order, although I do feel many of the symptoms and have been known to have panic attacks for no good reason at all. Since I started taking Source Naturals L-Tryptophan 500mg, 120 Capsules and 10 Grams Melatonin 99% Bulk Powder, this has no longer been the case. I sleep through the night, well most nights, and I haven't had anything that even closely resembles a panic attack for close to a over a year.

The Maltonin and L-Tryptophan have been the key reasons for this, and I can't begin to say enough good things about them. I think I've taken every variety of sleeping pill in the past, all of them always giving me groggy feeling in the morning, not so with these supplements what-so-ever I go to bed and drift into a peaceful sleep within 30 minutes and wake up feeling refreshed and ready to face the day with a positive outlook on things (not something I'm usually known for saying!).

5Helps me sleep!  Aug 06, 2010
By jsue
I am a shift worker. At 68 I sleep days and work 10-12 hour shifts at night. I live downstairs from very active and noisy neighbors. The major issue is of course uninterrupted sleep. I use a variety of products to help me sleep through the day and get 7 or more hours of sleep. This additive immediatly contributed to a sounder sleep. It has become a crucial weapon in my sleep arsenal.

5A WONDERFUL, NATURAL PRODUCT  Apr 06, 2008
By P. Gray
Source Naturals L-Tryptophan, 500 mg, Tablets, 120 tablets I have suffered from insomnia since I was about 11 years old and am now 40. This is the only natural product that I have tried that works! It is not an instant fix rather, it's a cummulative effect. I guess that I really began to notice it's benefits after about one month.

I also have some anxiety and nervousness so the dose that seems to work best for me is 2-4 tablets in the morning and 4 at night. I feel less anxious and more peaceful throughout the day and actually sleep at night, without worrying about becoming dependent on a chemical sleep aid or anxiety medicine. I highly recommend this product!!

5Awesome Sleep Aid and Mood Booster  Jun 15, 2010
By Kerri Elders
Source Naturals L-Tryptophan has performed miracles for me. It's an amino acid that helps build the brain's feel-good chemical, serotonin. I've used it for about 2 years after reading The Mood Cure: The 4-Step Program to Take Charge of Your Emotions--Today for its nutritional advice, upon the recommendation of this book: Protein Power: The High-Protein/Low-Carbohydrate Way to Lose Weight, Feel Fit, and Boost Your Health--in Just Weeks!.

I was shocked by the difference it made for me in the quality and quantity of my sleep. I'd spent the last year or two waking up, wide awake, at 3:30 in the morning & was unable to go back to sleep. I take 1500 mg of Tryptophan (3 500 mg capsules) and 400 mg of chelated magnesium before bed and now enjoy deep and restful sleep. [I've recently added in another supplement, melatonin; you can read more about that at the end of this review].

I find that I am more resilient, resistant to stress, & easygoing since taking tryptophan.

I experienced its incredible mood-boosting effect earlier this year after enduring a ruptured appendix. I suffered several complications & had to be put on super strong antibiotics that depleted all my B Vitamins and sent me into a quick but INTENSE bout of post-surgical depression (much like what heart bypass surgery patients experience, according to my surgeon). I spoke with my physician to get his approval, then took just 500 mg of tryptophan that afternoon and then 1500 at bedtime, as usual, and bounced back to my usual cheerful self within JUST 2 DAYS.

Just a suggestion--be sure you're taking it on an EMPTY stomach (about 1-1/2 hours after eating anything).

This is an amino acid & any trace of protein in your stomach will compete with the tryptophan. Don't take with milk; take with water (some experts suggest a couple of sips of apple juice--but I use H2o).

If 3 capsules at bedtime (or an hour before) on an empty stomach won't do the trick after a few days, then it's possible you aren't low on serotonin. If you awake groggy, you're taking too much.

Here's something else that works: 400 mg of CHELATED magnesium (not just magnesium oxide, make sure it is chelated magnesium); the best I know of is this one: Chelated Magnesium 200mg - 180 - Tablet. Works wonders for sleep and health; most Americans' magnesium levels are chronically low, which can lead to heart issues and other preventable diseases. Get this book to learn more: The Magnesium Factor.

Hope this helps someone out there; I wish I'd known about tryptophan 10 years ago!

P.S. For hardcore insomniacs for which tryptophan won't do the trick (give it time & remember to take on an empty stomach), try some melatonin; read my review of this product for more detailed info: Source Naturals Melatonin Complex Sublingual Peppermint, 100 tablets (Pack of 2)

****UPDATE P.S. Also, please remember that supplements work slowly, over time. Metabolisms vary. Educate yourself; I highly recommend you start with The Mood Cure: The 4-Step Program to Take Charge of Your Emotions--Today to quickly "zero in" on your own personalized needs. Good Health (and good sleep) to All!

5Excellent Sleep Aid  May 30, 2007
By Magna Veritas
I come from a long line of semi-insomniacs and have always had difficuly falling asleep and remaining so without waking up every hour or two. Since I have been taking 3 capsules of the tryptophan before bed I have been sleeping like a baby everynight and feel much more refreshed and rested during the day.
