Registry check · Melatonin
Does anyone independently verify Melatonin supplements?
2 of these 5 products are confirmed in USP Verified, which puts this category in the minority with any verified option at all. The other 3 are not listed anywhere we can check — not evidence against them, only an absence of independent confirmation.
This is one of the 8 long-established nutrients where verified options exist, unlike newer arrivals such as NMN or lion’s mane, where 14 of 17 categories have none. If you want a certified Melatonin product, you can actually buy one.
Certification is not a dosing guarantee. Across the whole catalogue, certified products reach the clinically studied dose 57% of the time and uncertified ones 71% — a gap too small to mean anything (Fisher p = 0.185). Read the Melatonin dose column either way.
5 checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.

What a day at the studied Melatonin dose costs here
The research on Melatonin uses 0.5 mg to 3 mg (physiologic dose raising blood melatonin to normal night range; timing matters as much as mg), and every one of the 5 products here reaches it in a single serving, so for once the price in the table and the cost of the dose are the same number. They run 4¢ to 18¢ a day.
The label trap on Melatonin:2017 analysis: 71% of products missed label by >10% (83% below to 478% above); 2023 JAMA gummies: 88% inaccurate; children's gummies 0-667% of label
Method: studied range from our own Melatonin dosage guide (PMID 23691095), priced against the 5 products above — capsules in whole servings, powders in fractions. Trial doses, not a prescription.
The shelf · Melatonin
The Melatonin shelf is unusually consistent
Across 5 products from 4brands, the cheapest day is Nature Made Melatonin 3 mg at 5¢ and the dearest Life Extension Melatonin 6 Hour Timed Release 300 mcg at 9¢ — a gap of 1.8×, where categories on this site routinely run 15× or worse. With Melatonin priced this tightly, the 4-brand question of who will verify their contents decides more than the price column does.
Method: the 5 Melatonin products above, compared on label facts — serving size, servings per container, form, price. Not a dosing recommendation.

What the published reviews of Melatonin concluded
- Effect of melatonin supplementation on sleep quality: a systematic review and meta-analysis of randomized controlled trials. · Journal of neurology, 2022
“We found that the treatment with exogenous melatonin has positive effects on sleep quality as assessed by the Pittsburgh Sleep Quality Index (PSQI) in adult. In adults with respiratory diseases, metabolic disorders, primary sleep disorders, not with mental disorders, neurodegenerative diseases and other diseases.”
- Melatonin Use in the ICU: A Systematic Review and Meta-Analysis. · Critical care medicine, 2025
“Our findings suggest that melatonin administration in the critically ill may improve perceived sleep and reduce delirium, without increasing adverse effects. Certainty of evidence was negatively affected by the risk of bias and inconsistency.”
- Meta-analysis: melatonin for the treatment of primary sleep disorders. · PloS one, 2013
“This meta-analysis demonstrates that melatonin decreases sleep onset latency, increases total sleep time and improves overall sleep quality. The effects of melatonin on sleep are modest but do not appear to dissipate with continued melatonin use.”
- Clinical pharmacokinetics of melatonin: a systematic review. · European journal of clinical pharmacology, 2015
“Despite methodological differences between the included studies, Tmax was approximately 50 min following oral immediate-release formulations of melatonin. T1/2 was 45 min in both administration routes.”
Method: PubMed searched in humans for systematic reviews and meta-analyses with Melatonin in the title; these 4 of the 8 that qualified are shown with the authors’ own conclusion quoted rather than summarised. What it cannot tell you: whether Melatonin will work for you — each of these reports an average across trials published 2013–2025, and null findings are shown here as readily as positive ones.
How these 5 Melatonin products were ranked
2 of these 5 are confirmed in a certifier's registry — the only melatonin rows where the claim is independently backed — and the rest are ranked on cost per day at the labelled serving. Commission does not enter it: the rate is the same whichever melatonin you buy. Full methodology.
