    This works well for me

    Posted by ellelisw on May 23, 2009

    I've been a restless sleeper for a long time and have tried many products to help. Tryptophan has brought the best results... I can fall asleep and sleep well without feeling "hungover" in the morning. The side effect is I'm more refreshed, calmer and happier throughout the day. I couple this with L-Theanine and/or relora when I'm especially stressed. I don't use it every night but I do find that, if I don't take it on a regular basis, my restlessness and sleeplessness return and I'm more stressed during the day. I've tried other labels for tryptophan, but of the brands iHerb carries, Source Naturals has been the most consistently potent and effective for me. Plus, the price cannot be beat.

    Love your Source Naturals, L-Tryptophan. If you had the larger bottles of 120... I'd love it!

    No more elusive sleep

    Posted by Reviewer3128508 on Feb 09, 2009

    I still wake up at night for normal things like bathroom trips, but I no longer lie awake for hours after. This works well; with no drowsy residue in the morning.
