I love natrols melatonin supplement. I have found they have changed the product recently though, the ingredients are not the same (it now contains wheat and soy and it did not before, I am gluten free so this is sad). Also no longer has vitamins Bs and calcium added, seems they have tried to make the product cheaper for them. New product also doesn't dissolve as nice in the mouth and is a lot harder, there was something satisfying about the old product that this new one doesn't have. Taste is also not as good. It still does its job though.
