So glad to find in the US again
Posted by Reviewer1358304 on Apr 09, 2009
I bought this plain L-Tryptophan and True Calm at iherb. It is the same combination I had in one product before it became illegal in 1989 in the US. I have discovered since buying these 2 products that Doctor's Best also makes L-tryptophan Enhanced with all ingredients of the 2 items I just got. I will buy that from now on. The combo puts a smile on my face and positive thoughts in my clear head. I love it for life!
Thought it would help me sleep -- it seemed to keep me awake!

Probably won't be re-ordering this one..

It's been awhile since I've taken the time to write a review, but I had to for this. I ordered this as a freebie to an order and have taken it 2 nights in a row after running out of my melatonin (Source Naturals 2.5 mg peppermint). It's now 4:00 am and I just unloaded the dishwasher! Not helping with sleep whatsoever, in fact it was hard to even fall asleep which I normally don't have a problem with, and I will not be taking these again (I thought maybe last night not sleeping was a fluke and decided to give them a 2nd chance). Can't wait for my melatonin to arrive!!
It does work, but a low protein diet is needed for it

The product from Doctor's Best seems to be of a very good quality. But talking about the L-Tryptophan, it needs a very low protein diet to work (amino acids "compete" for passage through the blood-brain barrier - BBB). As my protein intake is high and I don't suffer of any kind of depression, I don't know if it's worth changing my eating habits for it. I just have a small sleep disturb... But as the majority of people don't eat a high protein diet, it will work fine for mood, sleep, depression, appetite and immune system.

This induces sleep within thirty minutes and I find if I do happen to wake in the middle of the night I have no trouble falling quickly back to sleep!

Very good product,should defintately be sold worldwide. not many people seem to know about this, but most definately helps with the sleep process, and then with daytime activities to give you a much more positive outlook. Defintately will continue to use, as i much prefer the natural choice instead of doctors rx.

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.
