    doenst work for me

    Posted by Katarinatan on Jun 13, 2012

    I read all the wonderful reviews and wanted this to work badly for me. I have sleeping disorders: I cant fall asleep and I dont stay asleep for long. But unfortunately it didnt do anything for me.

    Completely ineffectual for me. Mindful relaxation prior to sleep is the best thing for me to have some success in reducing my sleep onset

    perhaps too early to say but so far experience has been good, if you want a product which is slow acting, and accumulating, then this is one for you. because tryptophan is a protein it has to be broken down, perhaps this is why you can't really feel the effects right away, it doesn't knock you out, but it definitely keeps you well rested through the night, as the proteins are broken down and helps you sustain a good night sleep. did not work very well

    Two of these and I am OUT. Most immediately effective supplement I've ever taken.

    I feel sleepy in a natural way by taking this medicine. I can sleep more than 7 hours and refreshed in the morning. I don't feel any side effect.

    I started my autistic son on this before bedtime. It has helped him sleep better than when the Dr had him on sleeping pills. He wakes up in a good mood. I will re-order.

    sleep effectiveness

    Posted by Reviewer3354796 on Jan 01, 2012

    Works great for sleep even if taken only once at bedtime. Packs an extra punch with the niacin and B6

    Great Product!!!

    Posted by Reviewer1898281 on Dec 11, 2011

    This has really helped with my moderate depression and anxiety. I encourage anyone who suffers from these conditions to give it a chance. I have been taking it for about a month. My mood is much more positve and feel more relaxed and focused. I tried the SSRI's and could not deal with the side effects.
