Product 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. |

helps depression and general health by kabuky (Germany)  5 Stars
November 19, 2009
I don't use tryptophan for insomnia though it does help me fall asleep. Instead, I tried some for depression issues. I have had chronic depression since a teenager; counseling helps but depression is always there. I started taking tryptophan 5 yrs ago; the effect was immediate! The next day, I felt much better and less anxious, depressed. I have known for decades that I fit all the symptoms of not having enough serotonin in my system but the only thing available in the USA were anti-depressants to affect the way the brain used serotonin. I know immediately when I run out - I get emotional, moody, weepy. This DOES help chronic depression and general malais. I take 2000-2500 mg at night; that seems to be the best dose for my body. This is my choice of helping myself until they are able to manufacture serotonin directly.

Excellent product by V. Vanderbent (Riverdale, NY USA) 5 Stars
November 14, 2009
Just one capsule does the trick for me. Was a bit hesitant at first despite all the rave reviews, concerned I wouldn't wake up refreshed in the morning, but no problem. Highly recommended, without any side effects!

Wonderful 'stuff'!! :-) by Nancy Sparks Morrison (Cross Lanes, WV) 5 Stars
November 04, 2009
I use 1500mg of L-tryptophan nightly to both help with sleep and to help my thinning hair. Sleep is wonderful and it seems my hair is doing better. My doctor recommended this to me.

Puts me to sleep by P. Krysl (CA, USA) 5 Stars
October 03, 2009
I usually take two tablets an hour before bed, and I sleep deeply. Not to mention, I have the wildest, most phantasmagoric dreams from l-tryptophan. These might be quite useful to people trying to lucid dream. the full dosage is three tablets, but I've never had to take that many. a bottle of 60 caps could last anywhere from a month to month and a half, so it is a good idea to stock up. Also, it is not a good idea to take MAO inhibitors in conjunction with this. sometimes Valerian / Kava Kava will do the trick and Gaia Herbs "Serenity" is great too, but l-tryptophan is what I mainly use.

Sad this didn't work for me by P. Harris (CA)  1 Stars
August 20, 2009
Made no difference to my hapless sleep pattern - I had high hopes after reading the reviews but found it didn't work for me - my husband and I shared the bottle and he sweetly suggested it 'might' have made a difference.
