This product can't be verified from public data Neither good nor bad — the checks below show what this listing publishes and what it withholds. Verifiable products publish more. Evidence availability only; this does not establish safety or effectiveness.
4 of 6 public trust signals found · 0 product-specific concerns
This product is certified by NSF International, assuring the identity and quantity of its contents and adherence to contaminant limits. While this certification doesn't speak to effectiveness, it provides a layer of verification. The product's listing shows 5mg of Melatonin per serving, but the NIH's database includes a label with 3mg of Melatonin, suggesting a potential discrepancy to look into. You can verify the NSF certification by searching for "OLLY EXTRA STRENGTH SLEEP" on the NSF Certified Products registry online.
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
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.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Label #180866 “Restful Sleep Blackberry Zen” (OLLY), entered 2018-09-21, with the full Supplement Facts on file — see the panel below. NIH marks this label as off-market (superseded or discontinued version). Company on file: Distributor — OLLY Public Benefit Corp., San Francisco, CA.
NSF’s certified-products registry lists “EXTRA STRENGTH SLEEP” under OLLY, Public Benefit Corporation. This certification covers identity and quantity of contents plus contaminant limits — not effectiveness. Verified directly against info.nsf.org at build time.
UPCitemdb resolves 840160202391 to "OLLY Extra Strength Sleep Multivitamin Gummies - Blackberry Zen - 90ct" (OLLY) — consistent with this listing.
Documented concerns
These are documented contradictions or claims that need more evidence. They are separate from missing data.
No contradictions or product-specific cautions were found at this check depth.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
What this means: the listing doesn't publish net weight, per-serving dose, servings per container, so the dose claim can't be checked against physics from public data. That's neither a pass nor a strike — but it does mean you're taking the label on faith. Checkable products publish these numbers.
Exact-listing history records written-review counts from 186 on 2026-01-27 to 241 on 2026-07-17 (net +55). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
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
Check for yourself — no one’s permission needed
Scan the barcode on the package and confirm it reads 840160202391.
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.
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.
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.
