    I find it to be more effective than some of the other tryptophan products that I have used in the past

    even better sleep, improved mood

    Posted by may291 on Apr 27, 2012

    Was suggested to me by my health care practitioner. I took one at bedtime each night. Even though I don't have a problem sleeping, sleep felt even a little more restful, and good for mood - depression and anxiety. I used this and Source Naturals brand, both were good.
