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 10 g of bovine collagen, and the NIH DSLD label shows 10 g bovine collagen 13 gram(s). Those amounts agree. This is internal consistency, not independent lab testing.

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.
NIH DSLD label #339219 (public label filing for this exact product) Amounts are shown as listed panel data, not independently lab-tested contents.
Every check we ran
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
label claims 10000 mg/serving — within the range commonly used in research (trials use 2.5–15 g/day of hydrolyzed peptides). Sources: PubMed search: collagen peptide supplementation trial, WebMD search: collagen.
Claimed collagen 10,000.0 mg is 77% of the ≈13,000 mg serving (serving size on the label, keyed to UPC 198168537985) — within physical limits.
Label #339219 “Grass-Fed Collagen & Colostrum Unflavored” (MK Supplements), entered 2025-09-25, with the full Supplement Facts on file. Company on file: Distributor — MK Supplements LLC, Alpharetta, GA.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
USPTO lists MK Supplement LLC (LIMITED LIABILITY COMPANY) in GEORGIA, 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.
The brand's store lists this exact barcode as “Collagen & Colostrum” (variant: Unflavored / 30) — identity confirmed across retailer listings.
Open Food Facts resolves 198168537985 to "Grass-fed Collagen & Colostrum" (MK Supplements) — consistent with this listing.
Written reviews rose from 23 to 34 between July 12, 2025 and August 4, 2026. The largest rise inside any single 30-day window was about 5, 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.
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.
The observed listing and the exact brand product page both claim third-party testing. Neither names the laboratory or links a product- or lot-specific report. Repeating the claim across two pages confirms the brand publishes it, not that testing occurred. NSF, IFOS, USP, and Informed-Sport were not checked in this record.
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.
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.
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.
Exact-listing history records written-review counts from 25 on 2025-07-05 to 34 on 2026-08-04 (net +9). 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
Ask the brand or seller
Answered by the panel: the 10 g listing number equals Calcium 77 mg + Bovine Collagen 10 g. What lot-specific document confirms those listed amounts?
The panel resolves what the headline number includes. The remaining question is whether the product in hand matches those listed amounts; ask for a lot-specific certificate of analysis.
Can you send the certificate of analysis (COA) for the lot number on my bottle?
A real COA names the testing laboratory, the test date, the lot it covers, and what was measured. “Third-party tested” with no document behind it is a marketing sentence.
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
Scan the barcode on the package and confirm it reads 198168537985.
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 |
|---|---|---|
| Quality-testing claim “…3RD-PARTY TESTED FOR PURITY…” | Claimed, not verifiable We looked for: the observed listing, saved 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. The exact brand page repeats a testing claim but names no issuer. 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. |
| Benefit claim “…10g COLLAGEN + 3g COLOSTRUM — THE COMBINATION MOST BRANDS SKIP EXPLAINING: Colostrum's growth factors (IGF-1, TGF-β) repair the gut lining and improve nutrient absorptio” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Ingredient evidence exists; on dose: label claims 10000 mg/serving — within the range commonly used in research (trials use 2.5–15 g/day of hydrolyzed peptides). |
“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 |
|---|---|---|
| collagen peptides | Studies typically use 2.5 g–15 g. This product’s amount could not be read from public sources, so no comparison is possible. | |
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.
