Natrol Time Release Melatonin Gummies, 10mg
Checked against public sources on August 3, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
FDA recall appears in this brand's history. An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

The checks, one by one

✓Matches the label1
◐Partly confirmed2
“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.
Ingredient evidence exists; on dose: label claims 10 mg/serving — above the range commonly used in research (sleep trials commonly use 0.5–5 mg; higher doses are not shown to work better and gummy products have repeatedly been found to differ from their labels).
Ingredient research can support context, but it is not a trial of this exact product.
△Claimed without support found1
We found no study of this product measuring the stated outcome over the stated timeframe.
?Couldn’t verify independently2
No named laboratory or lot-specific certificate was found for this exact product. The exact brand page names no testing issuer and links no product-bound report. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.
“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
We looked and found no public proof. That does not count against the product.

FDA recall appears in this brand's history
An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
Evidence and sources
This recall is not about the product on this page. Natrol, LLC recalled a different product on April 8, 2021. FDA has since closed that case. The recalled item was “Natrol Melatonin 3 mg, Tab 60 White bottle with purple flip-top cap.…”
Locked evidence record →Open the full source-linked findingThe label says 3 g of melatonin in 4 gummies — but not what those 4 gummies weigh
That weight is the one number that would let anyone check the amount on the front. We did not weigh it ourselves, so this is an open question, not a problem we found.
Evidence and sources
A serving is 4 gummies, and the panel lists 3,000 mg — 3 g — of melatonin in that serving. What the panel doesn’t give is the one number needed to check it: what a serving weighs. Gummies of this type usually run somewhere around 2.5 to 3.5 grams each, which would put 4 of…

The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
Evidence and sources
USPTO returned multiple live supplement-class records for the exact brand wordmark: NATROL, INC., Natrol, Inc., Natrol LLC. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
Locked evidence record →Open the full source-linked findingListing claim matches the Supplement Facts panel
The label promise and the Supplement Facts amount agree.
Evidence and sources
The listing claims 10 mg; the photo-read Supplement Facts panel shows Melatonin at 10 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
Locked evidence record →Open the full source-linked findingEvery ingredient shows its amount · 5 ingredients listed.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Locked evidence record →Open the full source-linked findingThe barcode identity checks out · 047469081737.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
The brand's store lists this exact barcode as “Time Release Melatonin Gummies, 10mg” (variant: 55 ct) — identity confirmed across retailer listings.
Locked evidence record →Open the full source-linked findingReaching a studied dose costs about $9/month
Comparing cost at a research-relevant amount shows how quickly the package is used and what the routine actually costs.
Evidence and sources
At 1.0 serving(s) a day to reach the low end of the studied range (0.5–5 mg), this product runs roughly $9 per month. A price observation, not a recommendation.
Locked evidence record →Open the full source-linked findingReviews rose from 64 to 113 between July 8, 2025 and July 20, 2026 — no sudden jump.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 64 to 113 between July 8, 2025 and July 20, 2026. The largest rise inside any single 30-day window was about 9, so the count moved in steps rather than in one burst.

Dose and research context
The label amount is shown beside the range used in the linked ingredient studies.
Melatonin
10 mg per serving — above the 0.5–5 mg/day used in the linked studies.
What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 10 mg of melatonin per serving. Studies we found used 0.5 mg–5 mg a day, so this sits above that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
