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 2.5 mg of biotin, and the listing-image panel shows 2.5 mg biotin 2 gummies. 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.

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 #62846 “Hair, Skin & Nails Gummies With Biotin Strawberry Flavored” (Nature's Bounty Optimal Solutions), entered 2016-07-25, with the full Supplement Facts on file. NIH marks this label as off-market (superseded or discontinued version). Company on file: Distributor — Nature's Bounty, Inc., Bohemia, NY, USA.
Written reviews rose from 246 to 445 between September 15, 2025 and August 16, 2026. The largest rise inside any single 30-day window was about 144, 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.
A serving is 4 gummies, and the panel lists 4,000 mg — 4 g — of biotin in that serving. What the panel doesn’t give is the one number needed to check it: what a serving weighs. Gummies of this type usually run somewhere around 2.5 to 3.5 grams each, which would put 4 of them near 10 to 14 grams. If that holds here, biotin would be a high share of the serving’s weight, and that is why we stopped on this number. But we did not weigh these gummies. The 2.5–3.5 gram figure is a general estimate for the format, not a measurement of this product. One published number would settle it: the weight of one gummy, or of a 4-gummy serving. Until then we can’t confirm the 4 g and we can’t dispute it. Nothing here says the product is short — only that the label doesn’t let anyone check. Checked September 3, 2026.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
The listing claims 2.5 mg; the photo-read Supplement Facts panel shows Biotin at 2.5 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
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 228 on 2025-09-08 to 445 on 2026-08-16 (net +217). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
This record does not hold an exact, supplement-class public ownership record for the brand. That is a LookCloser coverage gap, not evidence that the brand has no owner or that the product is improper.
Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.
What to ask and check
Check for yourself — no one’s permission needed
Compare the panel on the bottle in your hand to the one shown in this record.
Ours was read from listing photos and can contain reading errors. The physical label is the source of truth — if they disagree, tell us and we’ll correct the record.
Scan the barcode on the package and confirm it reads 074312016301.
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 |
|---|---|---|
| Benefit claim “…BEAUTY SUPPORTING BIOTIN: Nature's Bounty Hair Skin & Nails Pectin Gummies contain 2,500 mcg of biotin per serving; a vital nutrient to help support beautiful hair; glow” | Not checked yet We looked for: whether the ingredient doses on the label match the doses used in published research | Ingredient-level evidence for this formula isn’t in our knowledge base yet. Recorded as not checked yet — not as a negative. |
“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.
