Review: Good stuff! - This melatonin is definitely potent. Lights out all night for me. I take 1 gram. I was taking 80mg of a different brand but I would wake up sometimes and it would take me a hour to go back to sleep. I only wish they gave you more.
Review: Works for me - Works well for me. You might want a milligram scale to determine exact dosing. I contacted the company for clarification and they said the included spoon/scoop measures about 5-10mg.
