L-tryptophan as effective sleep aid?

The two quotes below are from another thread, viewtopic.php?p=234188#234188.

I want to start this separate thread to concentrate on L-tryptophan. Do you have any experience with L-tryptophan? Good? Bad? Dosage? Brands?

L-tryptophan was VERY effective for inducing a relaxed state and allowing one to easly fall asleep with NO Side effects to speak of other than a little bit of sluggish awakening in the morning.

jskinner/I thought that l-tryptophan gets converted into 5-HTP on its way to Serotonin? Using 5-HTP should mean that its less likely to get converted into other things along the way.

Correct, it does get converted. One would think that 5-HTP would work better but for some reason people have better results with the l-tryptophan.

As for melatonin, ehh didn't work too well for me for some reason. Initially I slept pretty well, fell asleep fairly easily. After a while the benefit of melatonin suplementation seemed to go away I stopped taking it as it was no longer effect for sleep.

My Mother used L-Tryptophan all the time to help her sleep before it was pulled from the market. But it does look like it is back on the market. Source Naturals sells all of the amino acids. Source Naturals is typically sold in Whole Foods or other Natural Food stores. If you do a google search, there is a ton of information out there.

I don't know what the dosage should be.
Not a lot of information but maybe helpful.
