Source Naturals, L-Tryptophan, 500 mg, 120 Tablets127 Reviews
The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.
The Shipping Weight includes the product, protective packaging material and the actual shipping box. In addition, the Shipping Weight may be adjusted for the Dimensional Weight (e.g. length, width & height) of a package. It is important to note that certain types of products (e.g. glass containers, liquids, fragile, refrigerated or ice packed) will often require protective packaging material. As such, these products will reflect a higher Shipping Weight compared to the unprotected product.

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

iHerb Customer Reviews
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!
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!
