What this is. We compare what a listing claims against what public records show — label arithmetic, barcode registries, NIH’s label catalog, FDA enforcement data, certification registries, and published research. Every statement below traces to one of those.
What the states mean. Confirmed = an outside source agrees. Contradicted = an outside source disagrees. Caution = something needs explaining. No data = we looked and found nothing — a gap, not a strike.
What it is not. A clean record is not an endorsement and never proof a product works. A thin record is not an accusation. We publish evidence and gaps; the conclusion is yours. Nothing here is medical advice.
Something wrong? Every figure is meant to be checkable — sources are named and linked. Send a correction and we’ll fix the record.
We did the comparison: the listing claims 60 mg of melatonin, and the listing-image panel shows 60 mg melatonin serving size: 1 capsule. Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| SLEEP 60® ADVANCED COMPLEX | 705 mg | — | |
| Melatonin | 60 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a listed “proprietary blend” (legal, but a transparency yellow flag). A label stating no amount at all is non-compliant — a checkable red flag. This panel states amounts; any remaining comparison concerns the front-label framing.

Every check we ran
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
USPTO lists Mando International LLC (LIMITED LIABILITY COMPANY) in TEXAS, USA for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itself prove who manufactures or sells this product.
Written reviews rose from 59 to 82 between July 26, 2025 and April 8, 2026. The largest rise inside any single 30-day window was about 7, so the count moved in steps rather than in one burst.
Documented concerns
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
The saved listing evidence does not establish net weight, unit count, per-serving dose, servings per container, so the dose claim cannot yet be checked against serving arithmetic. This is a neutral evidence gap, not a pass or strike.
Published sources describe how melatonin have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome. Sources: NIH NCCIH — Melatonin, PubMed search: melatonin dose sleep onset.
We have not found a public label filing for this exact product. That is a gap in our records, not evidence that no filing exists.
This means only that no enforcement record matched the brand name — it does not mean the product was tested, reviewed, or cleared by FDA. New and untested products also have no recall records.
Exact-listing history records written-review counts from 58 on 2025-07-19 to 82 on 2026-04-08 (net +24). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.
What to ask and check
Ask the brand or seller
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.
Where are the ingredients sourced, and where is the product manufactured?
“Made in USA” can describe only the final bottling step. Ask which country the actives came from and whether the facility is audited.
What is the amount of each ingredient inside the proprietary blend?
A blend total tells you nothing about whether any single ingredient reaches a dose used in research. Brands may decline — that answer is informative too.
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
Compare the panel on the bottle in your hand to the one shown in this record.
Ours was read from listing photos and can contain reading errors. The physical label is the source of truth — if they disagree, tell us and we’ll correct the record.
Scan the barcode on the package and confirm it reads 850053522604.
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.
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.
What the listing promises — claim by claim
| Claim | Status | What we found |
|---|---|---|
| Manufacturing claim “…GMP…” | Partly supported We looked for: the facility registration or certificate behind the claim | “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. |
| Origin claim “…MADE IN USA…” | Claimed, not verifiable We looked for: customs records or label filings showing where ingredients were sourced and where it was made | “Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product. |
| Benefit claim “…BOOST IMMUNE HEALTH WITH BETTER SLEEP: Lack of sleep can weaken the body's immune system, making quality sleep essential for overall health.…” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed. |
“No evidence located” does not mean a claim is false — it means the seller has not put evidence proportionate to the claim on the public record, and we could not find any. Absence of proof is not proof of absence.
This label vs. the doses studied
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Melatonin | shaded = doses used in studies (0.5 mg–5 mg) · bar = this label | 60 mg — above the studied range |
Matching a studied dose does not mean the product works, and missing it does not mean it fails — it shows whether the label and the research are talking about the same amounts. Not a recommendation to take any amount.
