5 of 6 public trust signals found · 0 product-specific concerns
This supplement is documented to contain 3 mg of Melatonin per serving, which aligns with the amount used in many sleep studies. While this dosage is within common research ranges, the research does not necessarily guarantee the same benefits for everyone. Currently, there is no information checked on the authenticity of this specific product based on marketplace patterns. You can verify that the "Supplement Facts" panel on the product bottle lists Melatonin at 3 mg per serving.
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
The listing claims 3 mg; the NIH DSLD label registry shows Melatonin at 3 mg per serving — an independently filed label agrees.
label claims 3 mg/serving — within 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.
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.

Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
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: “PRECISE PROBIOTICS WITH STRESS SUPPORT”. Certification covers contents and contaminants — not effectiveness.
Exact-listing history records written-review counts from 185 on 2026-01-22 to 247 on 2026-07-17 (net +62). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
What to ask and check
Check for yourself — no one’s permission needed
Scan the barcode on the package and confirm it reads 840160201738.
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.
