    Benefits have not been recognized

    Posted by Reviewer2420963 on Feb 06, 2012

    I've only tried these a couple of times and did not find that my quality of sleep was improved. I've score a 3 because it's possible that I just need to try them a few more times before a valid determination can be given.

    I take 5-HTP along with tryptophan, valerian and theanine with GABA for an excellent night's sleep.

    Great sleep aid

    Posted by Reviewer2595069 on Nov 03, 2011

    Use it as a sleep aid when I am over tired or restless. Helps with restless legs too. And you don't wake up groggy.

    Tryptophan Benefits

    Posted by Reviewer1949452 on Sep 28, 2011

    Very good product,should defintately be sold worldwide. not many people seem to know about this, but most definately helps with the sleep process, and then with daytime activities to give you a much more positive outlook. Defintately will continue to use, as i much prefer the natural choice instead of doctors rx.
