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
Ingredient amounts are hidden inside a blend
The panel lists “Nutrafol® Blend” as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.
Intake method matches the research
Nothing in this listing contradicts how these ingredients were studied (ashwagandha, collagen peptides, zinc). For example, ashwagandha: daily use over 6–12 weeks in studies; extract concentration matters (root powder ≠ standardized extract). Sources: NIH NCCIH — Ashwagandha, PubMed search: ashwagandha randomized trial.
UPC independently corroborated
UPCitemdb resolves 852661843751 to "Nutrafol Women's Hair Growth Supplement | Ages 18-44 | Clinically Proven for Vis" (Nutrafol) — consistent with this listing.
No data yet: Trademark owner candidates are ambiguous
USPTO returned multiple live supplement-related marks with the exact brand wordmark and different registrants. The owner is withheld until the product-to-mark identity is pinned down.
No data yet: Review-count history: not available
Marketplace rating 4.2★ across 18,554 ratings. No exact-listing count history was available, so no review-pattern claim is made.
Multi-ingredient formula — panel read, serving weight unknown
We read the full Supplement Facts panel from the photos (below), but the label doesn’t state a serving weight, so the arithmetic can’t run. A gap in the label’s information, not evidence of a problem.
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.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Clinical-evidence claim “…Women's Hair Growth Supplements, Ages 18-44, Clinically Tested for Visibly Thicker and Stronger Hair, Derma…” | No evidence located We looked for: a named, citable clinical study of this product or formula | No named, citable study of this product or formula was located in public sources. The claim may rest on ingredient-level research rather than a trial of this product. |
| Professional-endorsement claim “…ested for Visibly Thicker and Stronger Hair, Dermatologist Recommended - 1 Month Supply 1-MONTH SUPPLY: One (1) bot…” | 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. |
| Benefit claim “…Nutrafol Women Hair Growth Supplements that promote faster-growing, visibly thicker, fuller, str…” | 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 |
|---|---|---|
| ashwagandha | Studies typically use 250 mg–600 mg. This product’s amount could not be read from public sources, so no comparison is possible. | |
| 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. | |
| Zinc (as Zinc Amino Acid Chelate) | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 25 mg — 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.
Documented cautions
- zinc — daily oral use; sustained high intakes can interfere with copper absorption — a documented interaction, not advice
Statements from published sources about these ingredients — not advice about this product, and not a complete safety review. Anyone taking medication should talk to a pharmacist or clinician.
