The short read
This supplement contains 10mg of Melatonin per serving, which is a higher dose than what is commonly used in sleep research. While this dose may be of interest to some experienced users, studies typically use doses between 0.5mg and 5mg. The label math is consistent, and the UPC is independently verified, but this specific product has not yet been analyzed for authenticity. You can verify the brand's NSF certification status by looking up OLLY in the NSF Certified Products database online.
Why this result?
We ran this product through public-record checks — label math, barcode registries, FDA recall lists, published lab tests. This banner sums up what those checks could and couldn’t confirm. Green means nothing public contradicted the label — not proof it works or is safe. Gray means the data to check simply isn’t public: a gap, not a verdict. We show the evidence; the conclusion is yours.
Confirmed evidence
What checked out03
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
Taken the way the research studied it
Nothing in this listing contradicts how these ingredients were studied (melatonin). For example, melatonin: taken before bed; timing matters more than size of dose in the research. Sources: NIH NCCIH — Melatonin, PubMed search: melatonin dose sleep onset.
Barcode confirmed in an outside database
Open Food Facts resolves 840160202513 to "Sleep Maximum Strength 10mg" (Olly) — consistent with this listing.
Documented concerns
What needs caution01
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Dose is higher than studies used
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). Sources: NIH NCCIH — Melatonin, PubMed search: melatonin dose sleep onset.
Unresolved public record
What is still missing04
We looked for these signals but could not settle them from public sources. A gap is not a strike.
No label filed with NIH's public catalog
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
Certified by NSF — contents and contaminants checked
OLLY, Public Benefit Corporation appears in NSF’s certified-products registry with 10 certified product(s), but we couldn’t confirm this exact listing is among them. Closest listed product: “SLEEP STRAWBERRY”. Certification covers contents and contaminants — not effectiveness.
180-day review-count history is on file
Exact-listing history records written-review counts from 187 on 2026-01-24 to 286 on 2026-07-15 (net +99). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
This item belongs to a catalog variation family
The paid catalog links this exact item to a parent listing. Review counts on public product pages may be shared across sizes, flavors, or other variants, so the count history is listing context — not evidence that reviewers received or tested this exact variant.
What to ask and check
What would settle the open questions
Why is this shown?
Everything we couldn’t verify is something a person can still ask about. Rather than leave gaps sitting as dead ends, we turn each one into a specific question — the exact document, citation, or number that would settle it — plus the things you can confirm yourself with the bottle in your hand.
Ask the brand or seller
1
Can you send a clear photo of the full Supplement Facts panel?
It’s the one part of the label required to state what’s inside and how much. A seller who won’t show it before purchase is asking for trust the label would have earned.
2
Is this label filed with NIH’s Dietary Supplement Label Database (DSLD)?
Filing is voluntary, so absence proves nothing — but a filed label puts the full ingredient table on public record where anyone can read it.
Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.
Check for yourself — no one’s permission needed
1
Scan the barcode on the package and confirm it reads 840160202513.
A mismatch between the barcode on the box and the one on the listing is worth pausing over — it can indicate a different variant, a repack, or a counterfeit.
2
Look the product up yourself in NSF’s certified-products registry.
Search “OLLY, Public Benefit Corporation” at info.nsf.org — certification covers contents and contaminants, not effectiveness.
3
Check the lot number and expiry on the bottle against any COA you’re given.
A certificate that doesn’t name your lot doesn’t describe what you’re holding.
These are the open questions on this specific record — not a warning about the product, and not a suggestion to buy or avoid it. Getting them answered is how you decide for yourself.
