  "methodology": "Labels were enumerated from the NIH Dietary Supplement Label Database by paging its ranked search for melatonin-gummy terms and keeping only labels whose filed physical state is Gummy or Jelly and whose Supplement Facts carry a melatonin row; labels sold as melatonin (melatonin in the product name, not multivitamin, magnesium, sleep-blend or CBD gummies) were analysed. Melatonin per serving is the panel row for the panel serving; daily dose = per-serving x maximum daily servings; per gummy = serving / serving count. Every figure was recomputed in two halves split by label-id parity; figures that did not agree within 8 points (shares) or 25% (medians) are not published. Cost per night = Amazon price / servings.",
