I sleep wonderfully with this Tryptophan and awake refreshed. It's my second purchase.

We have been using this for insomnia for several years now. It seems to be a high quality product and works well.

I haven't tried this alone with no other sleep aids, so I do not know how much it is helping yet. I would try it again, though.
