The real cost of Melatonin, per dose
For the exact same amount of Melatonin — the same mg of active ingredient — the priciest products cost a 10× premium over the cheapest. We measured it across 65 tracked products, normalized to cost per mg.
Is the premium brand worth it?
On price, usually not. Two bottles of Melatonin can carry the identical active dose at wildly different prices — the spread between the cheap and the premium end is 10× per mg, from a low around $0.0083 to a high near $0.086. A higher sticker price is not a reliable signal of a better product; most of that gap is branding and margin, not more Melatonin. Pay up only for a verifiable difference — third-party testing, or a specific better-absorbed form — never for the packaging.
Right now the best value in our catalog is Piping Rock Melatonin 3mg | 250 Tablets | Adult Support… at $0.02 per serving — against a catalog median of $0.103/serving.
How we calculated it
Cost per active unit = price ÷ (servings per container × dose per serving), measured in Melatonin’s dominant dose unit (mg) so we only ever compare like with like — mg of Melatonin against mg of Melatonin.
Spread = the 90th-percentile cost per mg ÷ the 10th-percentile. Using the 10th/90th percentiles (not the absolute min/max) deliberately excludes one-off outliers and mislabeled listings. Based on 65 active Melatonin products from our live Amazon US catalog, recomputed hourly. This is a value comparison, not medical or dosing advice.
