## Customer Reviews

### ⭐⭐⭐⭐ Good Value - Strong Odor
            
*by L***A on May 24, 2015*

The product appears to be performing just like the much more expensive brand I was using - the only reason for the 4 stars is when I opened the jar there was no inner seal and a very strong odor.  I put the lid back on and didn't use for a few days.  After I went back to the container and opened there was no more odor.  Not sure what that was about and it did make me a little wary.
  

### ⭐⭐⭐⭐⭐ 1000ct is a great deal. Have used this brand for years
            
*by A***N on October 29, 2017*

1000ct is a great deal. Have used this brand for years. L-Tryptophan aids sleep in ~30-45 minutes, wears off in a few hours, and improves mood the following day.Combine with software like f.lux to adjust bright light exposure from screens, etc. based on schedule to fix sleep issues.
  

### ⭐⭐⭐⭐⭐ Cost-Effective with Superior Quality!
            
*by L***T on August 2, 2015*

A most cost-effective way to buy L-Tryptophan.  I have never been disappointed by the quality of the product and would highly recommend this company to anyone.  I have been using their services for the past three years.
