    Helps with sleep

    Posted by Reviewer2953495 on Nov 24, 2011

    I take 5-HTP along with tryptophan, valerian and theanine with GABA for an excellent night's sleep.

    When melatonin doesn't work, this does.

    Love that it is an all natural product. Just be sure to do compatibility checks with any meds or other supplements that you already take, as you can overdo and suffer with seratonin syndrome, a very frightening and possible fatal syndrome. Be, especially, wary if you are taking SSRI antidepressants.

    I have had insomnia for most of my life, this is the only thing that helps me get sleep. I usually take 2 a half hour before bedtime. This product also helps with anxiety.I am very happy with the improvements this gives to the quality of my life.

    It works!

    One pill taken about 30 minutes before bed on an empty stomach really does seem to help with sleep. I also use quick-dissolving sublingual melatonin (by Natural Factors) at the time I get into bed. A good combo!
