    this is a great product!! I take one with 3mg Now Foods Melatonin and sleep soundly thru the night. I wake up feeling refreshed and clear....long, long history of insomia that runs in family.

    My husband is sleeping better since using this, but sometimes it doesn't work as good as another time.

    Finer texture

    Posted by Reviewer1632304 on Jul 29, 2010

    I open the capsules because I cannot swallow pills...well, this is a finer texture without much taste...it is much easier to take.

    Jarrow's L-Trytophan

    Posted by Reviewer2328138 on Jul 12, 2010

    This is a very good sleeping help. Sleep like a baby. I don't have much problem sleeping but this really backs up the calcium/magnesium that I take before bed. If you take this with the Suntheanine you'd better be ready to go to bed as you really get drowsy. Recommend.

    Natural better night's sleep

    Posted by Reviewer2768761 on Jun 27, 2010

    Jarrow L-Tryptophan helps me fall back to sleep if wake up in the middle of the night, so I can get a full night's sleep.

    Good for sleeping, don't mix with 5HTP though.
