Tryptophan by Source Naturals

Posted by Reviewer2809978 on Jun 25, 2009

A night's sleep without L-Tryptophan isn't a Good night's sleep. I'm 58 and have been getting a normal night's sleep for about five years now, since I started supplementing with tryptophan. One 500mg tablet when I'm ready to fall asleep is all I need (actually I take about 0.25mg melatonin along with it[and sleep like a baby])

I have used this product along with iodine drops for depression and they are awesome I think anyone who suffers from depression should seriously consider this product.

good night's sleep

I am at that age where it is often difficult to get a good night's sleep. However, if I take one capsule of L-Tryptophan, along with Melatonin, I can get the rest I need.

Most sleep products haven't worked for me, but this product combined with Source Naturals NightRest with Melatonin has helped me.

This product is wonderful, it helps relaxes you and since I have been taking it I now fall asleep much more easily and stay asleep. I don't wake up in the morning feeling drugged up, there are no side effects and it is a wonderful supplement. I will continue to use this product, and recommend it to my friends to try. Ann
