  "methodology": "Labels were enumerated from the NIH Dietary Supplement Label Database by paging its ranked search for electrolyte and hydration powder terms and keeping only labels whose filed physical state is Powder, whose panel carries a sodium or potassium row, and whose product name says electrolyte or hydration; protein, pre-workout, greens and amino powders were excluded. Sodium, potassium and magnesium are the Supplement Facts rows for the panel serving. 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 1,000 mg sodium = Amazon price / (sodium mg per serving x servings) x 1,000.",
