The new Melatonin Sleep Spray contains melatonin along with a number of other calming supplements. While the label suggests 5 sprays many are actually finding that only one spray is needed. Some adults testing the formula have in fact required 5 sprays for a full night of sleep but other adults and younger individuals only need a single spray. The technology in these spray formulas is unique and appears to provide much greater bioavailability which is excellent, so this is a long way of saying that I would start off with a single spray and increase as needed for sleep.
