Great value

Posted by iHerb Customer on May 23, 2008 | Verified Purchase

Now only half the tryptophan for the money. They are selling a 50 gram package for the same as the 100 gram used to cost!!!

Thanks for your feedback!

Hopeful in Canada

I have only using L-Tryptophan Powder for 2 weeks, so I still looking for it to take long term effect. However I have had a reduction in anxiety and erratic eating.

Thanks for your feedback!

Tryptophan, a good product

Posted by iHerb Customer on Dec 11, 2007 | Verified Purchase

This stuff is really good, and helped me sleep the first couple times I used, it. It seems to have a tolerance level you hit then it doesn't have the same effect, so you really can't rely on it nite after nite to help you sleep. Good stuff to have around though.

Thanks for your feedback!

Best L-Trytophan Powder

I found this product pretty effective for helping to get to sleep.

Thanks for your feedback!

Works well but...

It works well but it's a little bitter so you really need to mix it into apple sauce or something w/similar texture if you don't drink fruit juice. I'm going to put the rest into my capsule maker.

Thanks for your feedback!

OK

This seems OK, a bit bitter taste. I have not noticed a great improvement in my sleep, but I also have not been taking it very regularly.

Thanks for your feedback!

L-tryptophan

Posted by iHerb Customer on Oct 10, 2007 | Verified Purchase

I'm a chronic insomniac and I started taking 2g an hour before bed, on an empty stomach, a week ago. Already, I'm sleeping better and I am no longer struggling through the days, yawning continuously. (my sleep hasn't been perfect, hence the 4 star rating, but maybe I haven't been taking it long enough) Powder is difficult to mix, however it doesn't taste too bad.

Thanks for your feedback!
