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.
What the label discloses
The listing-image panel publishes an amount for each of its 13 declared rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Calories | 35 | — | |
| Total Fat | 1 g | — | |
| Sugars | 0 g | — | |
| Protein | 8 g | — | |
| Sodium | 3 mg | — | |
| Vitamin C | 120 mg | — | |
| Vitamin E | 45 mg | — | |
| Biotin | 10 mg | — | |
| Hydrolyzed Fish Collagen Peptide | 9000 mg | — | |

| Hyaluronic Acid | 120 mg | — | |
| Methylsulfonylmethane (MSM) | 50 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a declared “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; the open question is whether those declared amounts are independently verified and how they compare with relevant research.
vision:google/gemini-flash-1.5 Amounts are shown as declared panel data, not independently lab-tested contents.
Every check we ran
Panel carries documented template or translation artifacts
The panel carries these quoted observations: “Calories has no unit”. US-market labels are produced under cGMP controls; these are template or translation artifacts worth checking, not proof that the label is fabricated or that the product is unsafe.
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.
Exact trademark owner identified
USPTO lists NATURAL TARGET LLC (LIMITED LIABILITY COMPANY) in MASSACHUSETTS, 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.
No data yet: Testing claimed — documentation not found
The observed listing claims third-party testing without naming a lab or certifier. No product-bound report is retained, so the claim cannot be verified as stated. NSF, IFOS, USP, and Informed-Sport were not checked in this record.
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.
Research context is available for the listed ingredients
Published sources describe how collagen peptides have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome. Sources: PubMed search: collagen peptide supplementation trial, WebMD search: collagen.
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: the observed listing, retained brand product page, any linked COA or test report; NSF, IFOS, USP, Informed-Sport were not queried | No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur. |
| 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.
