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.

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!
Taken along with vit. B6 at bedtime helps to stay asleep all night. I cut the 500mg. tab in half, with 25mg. of B6.
All around GREAT!

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

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.

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.
Great stuff :)

I take this every night to get to sleep. Before using this I couldn't get to sleep & would be awake till 3am. Highly recommended!
