## Description

Encourages Positive Mood* Promotes Restful Sleep* L-Tryptophan is an essential amino acid; therefore, it is not synthesized by the body and must be obtained from the diet.* L-Tryptophan is critical for the production of serotonin and melatonin, which help to support a positive mood, healthy sleep patterns, and proper immune system function.* Every lot of NOW® L-Tryptophan is tested to be free of Peak E and microbial contamination. Natural color variation may occur in this product.

Review: Quality - this product is AMAZING-I have purchase different teas and sleep tablets to help me fall asleep and stay asleep well one night the family was over and because of the laughing and playing and recalling old memories I did not take anything and because it was late pass 10 pm I could not drink my tea so the only thing left was the Tryptophan and wow I slept all night and I did not get up until 7 and I felt so good that I was able to get on with my usual activity -I recommend these pills for a good night sleep with few pills
Review: Great for Sleep, Unwinding - I was looking for something that would help calm my natural anxiety and help me relax before bed time. My doctor has recommended that I go to bed earlier, and it was a struggle at first to get myself to relax enough to be able to fall asleep early. L-Tryptophan is fabulous. I take one capsule to take the edge off earlier in the evening, and then one about a half hour or so before I want to actually go to sleep. It does its job! It does not, however, stop me from waking up in the middle of the night. I typically wake up anywhere from one to four or five times a night. Perhaps at a higher dosage it would, but I am nervous about taking too much and "snowing myself" for the following day. As far as I can tell it doesn't make me groggy at all in the morning which is great. I would recommend this product to anyone who is struggling with anxiety and/or needs help falling asleep. It is far safer than a prescription sleep medication. I have been on products like Ambien and trazodone in the past, and these had the effect of making me feel tired all day afterwards, as well as giving me unbelievable brain fog. Stick to natural solutions if you can! Other tips: use a red light in your environment before bed time; do deep breathing/meditation before bed; stop watching tv/computer about a half hour or earlier before bed etc. So many times we tell ourselves "oh there is no way that would work" or "I don't have time for that," but honestly, rest is so important - make time for yourself. Your body will thank you.

## Questions & Answers

**Q: What is the difference between this product and the L -Tryptophan that was removed from store shelves years ago?**
A: I was diagnosed with EMS in 1989.  I was one of the lucky ones and fully recovered. There was no cure. The “treatment” was discontinued use of L-tryptophan, steroids and 2 yrs of PT for me. Someone said EMS was treated with L-tryptophan?  Ridiculous.  We were being told by physicians to double up our dosages BEFORE they knew that was the root cause. I was sent to every specialist because every system in the body was impacted. 
Big pharma may have upped their game on regulating their manufacturing standards. But Supplements like L-Tryptophan do not fall under big pharmaceutical. They are not regulated with the same standards. Yes, do your HW. And no, this was not part of some crazy Prozac conspiracy plan.

**Q: What's the difference with 5-HTP?**
A: 5-HTP is converted in the body from L-Trytophan (also, can be made from the seeds of a particular African plant). It can have more wide-ranging side-effects (beyond brain/mental issues), so be careful with it when taking directly. When taken with other herbs, effects can amplify, so be careful. Always check with your medical doctor before taking 5-HTP. 5-HTP gets converted to serotonin by the liver. 5-HTP is not sold over-the-counter in all countries of the world. L-Trytophan, as a naturally occurring amino acid,  is commonly viewed as the safer alternative.

**Q: How big are the capsules?  I bought the other brand on amazon and they are too big.I have a problem with my esophougus and it got stuck and made be sick for a day. Thanks**
A: I have trouble swallowing pills, but there's a positive with this when it comes to ANY amino acids: They are best taken by opening the capsule into 1-2 oz of water and swishing in your mouth before swallowing. It allows them to absorb better AND work faster.

**Q: is the tryptophane from China??**
A: According to a message I got back from NOW:"The tryptophan is produced by fermentation of non-GMO corn in China; then is granulated, encapsulated, and bottled in the USA."

### ⭐⭐⭐⭐⭐ Life-Changing Supplement
*by M***. on January 24, 2025*

I’ve been using NOW Foods L-Tryptophan 500 mg for a few months, and I am truly amazed by the difference it’s made in my daily life. I’ve struggled with anxiety and irritability symptoms for years, and this supplement has been a game-changer. Since I started taking it, I’ve noticed a significant reduction in anxiety and mood swings. I feel more relaxed, focused, and less easily frustrated throughout the day. What I love most is that it doesn’t cause any drowsiness or side effects – just a natural sense of calm and well-being. The capsules are easy to take, and the 120-count bottle lasts a long time, making it a great value. If you're dealing with similar symptoms, I highly recommend giving this a try – it’s been incredibly helpful for my mental health!
