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.

“CERTIFIED”
Evidence →“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.
“Natrol Melatonin 10 mg Gummies, Sleep Support for Adults, 140”
Evidence →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.

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.…”

The label says 4 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 4,000 mg — 4 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…

Registered owner records: NATROL, INC. · Natrol, Inc. · Natrol LLC
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.

Listing 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.

Every 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.

The barcode identity checks out · 047469076832.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
Open Food Facts resolves 047469076832 to "Natrol melatonin chews" () — consistent with this listing.

Background reading
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.
