This is brilliant

Posted by Reviewer2776030 on Jan 07, 2017

I love this stuff. It doesn't hurt my stomach as many brands do and it works. I have reactive gastritis. Other brands actually give me insomnia and I figure it's to do with the way the supplement affects my gut. The slow release formula must provide a buffer. It's magic. I take 1-2 a night, depending on how wired I am

Never ever trying any other HTP product out there again!

Posted by 4697074565455776847 on Jan 06, 2017

I only take HTP + 1/4 of Natrol's melatonin 3mg to help me wake up refreshed and not drowsy the next day. It worked for me for ages until I decided to try another brand. I was awake until 3am with the one for the last few days. I thought I'd save money from switching to that brand from Natrol TR 100mg, sadly, I was mistaken. As they say, why fix something that isn't broken! Now bought 2 more bottles of this brand and never changing brands again!

Has an effect

Posted by Reviewer1923206 on Jan 06, 2017

I have two daughters who use this who sometimes feel depressed, and they tell me this product makes difference for them. Well worth giving it a chance, would recommend it to anyone looking for inexpensive options to elevate moods.

Excellent mood normalizer at a great price

Posted by 5322249426383897036 on Oct 18, 2016

It is a small pill and easy to swallow. I started taking this for better sleep and within 5 days I was sleeping 8+ hours and dreaming again. Take together with Melatonin.
