    Very satisfied!

    Posted by Reviewer2534274 on Apr 11, 2009

    I was a little concerned about ordering my supplements on line but I've very pleased at the value and perfomance I'm receiving. I had decided to try this service with one item and just ordered the rest of my amino acids from iHerb.com!

    I think this does help me to sleep more deeply, with no side effects the next morning!

    Great for helping me fall asleep

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

    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!

    Works wonderful for good nights sleep

    Posted by Reviewer2943679 on Jun 25, 2009

    I really like this product much better than melatonen. Don't wake up with the drugged feeling.
