Product works fast, but doesn't last all night. I get about 4 hours sleep, then am wide awake.

Doesn't make you sleep better, waste of money!

It really caused a great deal of stomach pain, and I had a worse night sleep than I did before taking it. Could just be me, but I had to throw it away after taking one capsule.
Good quality, but not for me

This product is a good choice, but having tried a number of different serotonin precursors including 5-HTP I recommend you to better try pharmaGABA and/or Taurine if your main problem is anxiety, because this can make you more depressed due to its dampening effects over noradrenaline.

Tryptophan is far superior to anything else I've tried for sleep, including strong and toxic drugs. Two grams of this plus valerian and I'm off to dreamland, awaking easily and with no "hangover." Thanks iHerb for making such great products available at the best prices to be found!
