Properly manufactured
Melatonin doesn't work for me. HOWEVER, the Amazon brand is on a fairly short-list of Melatonin supplements which have received approval from the National Sanitation Foundation, which was established after WWII. The Foundation insures that the supplements are compounded properly with safe ingredients in a sanitary facility, ie that you get what is on the label and it's clean. This is its classification: NSF/ANSI Standard 173 Dietary Supplements. This info is available on their website. So there's that.
