    Well I really believed this to be what I needed for a good nights sleep- but it didn't work. I can't believe it!

    Helps restore serotonin

    Posted by Reviewer1020169 on Mar 15, 2011

    We find that taking even one of these on an empty stomach in late afternoon PLUS having a bedtime snack of complex carbs with NO PROTEIN not only improves our sleep, but also helps with a brighter outlook the next day. We read in a book by K. DesMaison that eating tryptophan rich foods (especially animal protein) during the day then having the complex carb bedtime snack raises levels of serotonin while we sleep. It's something about the glucose helping the tryptophan cross the blood brain barrier, and tryptophan is necessary for serotonin and melatonin production. We just can't seem to eat enough meat most of the time so we take the tryptophan. I don't really understand all that biochemistry, but it works. It took a week or so of being consistent before we started seeing consistent results. It's well worth the price and far better than taking sleeping pills or Prozac! Hallelujah!

    Excellent Results

    Posted by Reviewer2009889 on Mar 11, 2011

    I have been using this this brand for a long time. When I am overstressed, I turn to this product. It's a great help to overcome the traumas that arise unexpectedly. It is also very calming when I am overstressed and can't sleep.
