    Just as good as prescription

    Posted by MusettaRose on Jan 09, 2015

    In the past I've had prescription to tryptophan, which was 3 to 4 times as expensive for me. This is just as good. I'm weaning off effexor, and I've been increasing my dose slowly with each reduction, with the help of naturalpath , to the point that I'm taking 4 tryptophan pills throughout the day, and I'm down to only 30% of my effexor pill, with absolutely no withdrawal effects!

    Great for helping me fall asleep

    Posted by Reviewer1645968 on Nov 11, 2012

    I'm trying many supplements to help me sleep; so far L-tryptophan the most helpful for me; I use it with melatonin.

    This is really good stuff especially if you're having a hard time falling asleep.

    Love that it is an all natural product. Just be sure to do compatibility checks with any meds or other supplements that you already take, as you can overdo and suffer with seratonin syndrome, a very frightening and possible fatal syndrome. Be, especially, wary if you are taking SSRI antidepressants.

    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.

    Helps with sleep

    Posted by Reviewer2953495 on Nov 24, 2011

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

    When melatonin doesn't work, this does.
