Registry check · Melatonin
Does anyone independently verify Melatonin supplements?
1 of the 5 Melatonin products on this page is confirmed in USP Verified: Nature Made Melatonin 3 mg. For the others, the listing may name a certification, but we did not find it in a public registry — that is 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.
The 5 products on this page checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.

Dose check · Melatonin
Does one serving reach the studied Melatonin dose?
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). 3 of the 5 products here reach the low end in a single serving; Life Extension Melatonin 300 mcg; Life Extension Melatonin 6 Hour Timed Release 300 mcg need more than one.
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), checked against the 5 products above that state a dose — capsules in whole servings, powders in fractions. Trial doses, not a prescription.
The shelf · Melatonin
