This is great

Posted by Reviewer3080687 on Nov 20, 2008

I love having it in powder form without the fillers. Getting the extra tryptophan makes my body flow more normally with the rhythms of the day -- like going to sleep at the right time. It a very effective product for me.

Amazing results

Posted by Reviewer1814780 on May 22, 2010

This review is for L-Tryptophan, and this brand works great. I have not tried any other brand, however. We use 1/4 tsp, 3 times/day, (per Dr. Daniel Amen), and it has significantly reduced everyday stress and anxiety. We just take things more in stride. We tried 5-HTP first, but this works much better for us.

Take with Gaba

Posted by Reviewer1385103 on Oct 10, 2012

I take a dose of this and a dose of Gaba for an excellent nights sleep. I have given this to habitual insomnacs and they have slept through the night for the first time in years.

Not sure about this one yet. I took L-trytophan way back before the FDA banned it. I remember it working better than this one has. The jury is still out on this one.

...if you want to be able to measure doses more precisely than what comes in capsules.
