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!
Taken along with vit. B6 at bedtime helps to stay asleep all night. I cut the 500mg. tab in half, with 25mg. of B6.
They work but space you out the next day

Take as instructed. They work but I feel off the next morning. Won't finish the bottle for that reason.
완전 푹 자요 for sound sleep

샤오미 미밴드 사용하면서 수면패턴측정하는데 deep sleep light sleep 구분할정도로 아주 미세하고 진짜 측정 정확하다 싶었는데 이거 복용한 날은 미밴드가 sleep data를 감지 못할정도로 시체처럼 자나봐요 자고 나면 푹잔 느낌입니다. 그래도 최소 6시간은 자야 개운하지 중간에 깨면 더 졸리더라구요.

It took a couple of weeks to feel the benefits of this product but my sleep definately improved and my anxiety was moderately reduced. Had some weird dreams though. Really weird! My son son also found this helped him to sleep during a stressful period at university.
Better than Rx s'

read this before buying tryptophan

first of all i have used it for more than 4 weeks and haven't noticed any change and second of all i found out today that tryptophan is unsafe and has some serious side effects and if i knew about that earlier i wouldn't have bought it. it is not safe people so don't risk your life for it.
