The only reason IMO, beside the pharma companys and pill dispensing doctors being threatened by natural drugs, oops, pardon, supplements, some countries have banned melatonin only because hormones are automatically classified as drugs. lol go figure
Warning labels for what? Melatonin is safe compared to most of the Koma Unwind ingredients. The warning labels should be for this. INGREDIENTS: Potassium Benzoate (A Preservative), Artificial Flavor, Red 40, Blue 1.
