How to read this report
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.
Every check we ran
Intake method matches the research
Nothing in this listing contradicts how these ingredients were studied (collagen peptides). For example, collagen peptides: daily oral use over 8+ weeks in studies. Sources: PubMed search: collagen peptide supplementation trial, WebMD search: collagen.
Each ingredient’s amount is disclosed
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
No data yet: Testing claimed — documentation not found
The listing claims third-party testing without naming any lab or certifier, so the claim can't be verified as stated.
No data yet: Review-count history: not available
Marketplace rating 4.6★ across 459 ratings. No exact-listing count history was available, so no review-pattern claim is made.
No physical impossibility in the listed amounts
Technical check only: the panel’s 9 actives sum to 10,025 mg, which fits inside the ≈10,000 mg serving. This means the numbers are physically possible — it does not mean the formula was validated or the contents confirmed.
Photo-read pack math is internally consistent
35 servings × 10 g = 350 g, matching the printed net weight 350 g (NET WT: 12.35 oz (350 g)). This checks agreement within the photo read; it is not an independent contents test.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Quality-testing claim “…QUALITY - Our hydrolyzed marine collagen is third-party tested for purity & potency and manufactured in a G…” | Claimed, not verifiable We looked for: a named laboratory, a certificate of analysis, or a certification-registry entry | No named laboratory, no certificate of analysis, and no certification-registry entry matching this product was located. |
| Professional-endorsement claim “…Heals The Entire Body From Within SUGAR FREE DOCTOR FORMULATED SUSTAINABLY SOURCED GLUTEN FREE WILD-CAUGHT…” | Marketing credential We looked for: who the professionals are, whether they were compensated, and what the endorsement covers | A professional endorsement is a marketing credential, not clinical evidence. Public sources don’t establish who was consulted, whether they were paid, or what specifically they reviewed. |
| Manufacturing claim “…d for purity & potency and manufactured in a GMP-certified facility to ensure it meets premiu…” | Claimed, not verifiable We looked for: the facility registration or certificate behind the claim | Facility-level claims can be accurate and still say nothing about this product’s contents. No registration document was located. |
| Benefit claim “…ER Marine Collagen Peptides Powder for Joint Support, Hydrolyzed Type I & III Fish Collagen with…” | 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 — see Related research below. 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
Why is this shown?
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Hydrolyzed Fish Collagen Peptide | shaded = doses used in studies (2.5 g–15 g) · bar = this label | 9 g — within 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.
Verifiability profile — 1 of 6 public signals
What this listing gives the public to check. Publishing these signals doesn't prove quality — but withholding them means claims can only be taken on faith.
