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 “Advanced Hair Complex” 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 (magnesium). For example, magnesium: daily oral use; chelated forms (glycinate) are studied for absorption — note labels may state compound mass rather than elemental magnesium, which differs ~7-fold. Sources: NIH ODS — Magnesium fact sheet, PubMed search: magnesium glycinate supplementation.
UPC independently corroborated
Open Food Facts resolves 074312012518 to "Hair Growth" (Nature's Bounty) — consistent with this listing.
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.
180-day review-count history is on file
Exact-listing history records written-review counts from 503 on 2026-01-25 to 520 on 2026-03-24 (net +17). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Clinical-evidence claim “…ne, 1 Per Day, 30 Capsules, One Month Supply CLINICALLY SHOWN RESULTS (1): Experience thicker, fuller hair…” | 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. |
| Benefit claim “…Hair Growth supplement; providing structural support for existing hair growth for noticeable impr…” | 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 |
|---|---|---|
| Arginine Silicate Inositol (Providing 10 mg | shaded = doses used in studies (200 mg–420 mg) · bar = this label | 10 mg — below 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
- magnesium — daily oral use; chelated forms (glycinate) are studied for absorption — note labels may state compound mass rather than elemental magnesium, which differs ~7-fold
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.
