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.
UPC independently corroborated
UPCitemdb resolves 031604003708 to "Nature Made Maximum Strength Dosage Vitamin C Gummies 1000mg per Serving - Tange" (Nature Made) — consistent with this listing.
Listing claim matches the Supplement Facts panel
The listing claims 1 g; the photo-read Supplement Facts panel shows Vitamin C (as Ascorbic Acid & Sodium Ascorbate) at 1 g per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
Reaching a studied dose costs about $73/month
At 2.5 serving(s) a day to reach the low end of the studied range (2500–15000 mg), this product runs roughly $73 per month. A price observation, not a recommendation.
Not found in NIH's DSLD label registry
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
FDA recall appears in this brand's history
Brand-level context only, not a finding about this product. Pharmavite recalled a different or not-exactly-bound product on 2016-06-06: “Specific lots of Nature Made(R) Vitamin D tablets may exceed specifications for yeast/mold.” (status: Terminated). The recalled product was: “Nature Made(R) D3 1000IU, 125 count, UPC 0-31604-02793-3” — not necessarily the product on this page. Verify at FDA’s recall database.
180-day review-count history is on file
Exact-listing history records written-review counts from 260 on 2026-01-24 to 320 on 2026-07-09 (net +60). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
This item belongs to a catalog variation family
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.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Benefit claim “…C 1000mg per Serving, Adult Vitamin C Immune Support Gummies, 80 Gummies for Daily Immune Support…” | 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 |
|---|---|---|
| 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.
Verifiability profile — 5 of 6 public signals
