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 9 declared rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin D (as cholecalciferol) | 20 mcg (800 IU) mcg | — | |
| Folate | 200 mcg DFE mcg | — | |
| Vitamin B12 (as cyanocobalamin) | 5 mcg mcg | — | |
| Biotin (as D-biotin) | 3000 mcg mcg | — | |
| Iron | 0.4 mg mg | — | |
| Zinc (as zinc citrate) | 5.5 mg mg | — | |
| Copper (as cupric sulfate) | 0.45 mg mg | — | |
| Keratin | 150 mg mg | — | |
| Amla Extract (Emblica officinalis, fruit) | 25 mg 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
No data yet: Review-count history: not available
Marketplace rating not shown★ — rating count unavailable. 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 listing-image panel (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.
Research context is available for the listed ingredients
Published sources describe how zinc have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome. Sources: NIH ODS — Zinc fact sheet, PubMed search: zinc supplementation trial.
Brand holds NSF/ANSI 173 certification (brand-level)
OLLY, Public Benefit Corporation appears in NSF’s certified-products registry with 10 certified product(s), but we couldn’t confirm this exact listing is among them. Closest listed product: “ULTRA STRENGTH PRENATAL SOFTGEL”. Certification covers contents and contaminants — not effectiveness.
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 “OLLY Ultra Strength Hair Softgels, Supports Hair Health, Biotin, Keratin, Vitamin D, B12…” | 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 |
|---|---|---|
| Zinc (as zinc citrate) | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 5.5 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
- 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.
Verifiability profile — 2 of 6 public signals
What this listing gives the public to check. Publishing these signals doesn't prove quality — but withholding them means claims can only be taken on faith.

Where it sells
A brand storefront was found, but no exact-product price was published or identity-bound at build time.
Brand store olly.com: 71 supplement products (+2 merch items) — for comparison, single-focus brands typically carry 5–30 products; very broad catalogs are common among companies that rebrand ready-made formulas — a pattern note, not a verdict.
