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 12 separately quantified rows and 1 combined blend total. Ingredients inside a blend do not have separate amounts.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin A (as Retinyl Palmitate) | 1200 mcg | — | |
| Vitamin D3 (as Cholecalciferol) | 2.5 mcg | — | |
| Thiamin (as Thiamine HCL) | 5 mg | — | |
| Riboflavin | 5 mg | — | |
| Niacin (as Niacinamide) | 5 mg | — | |
| Vitamin B6 (as Pyridoxine HCl) | 5 mg | — | |
| Folate (as Calcium L-5-Methyltetrohydrofolate) | 340 mcg DFE | — | |
| Vitamin B12 (as Methylcobalamin) | 20 mcg | — | |
| Biotin | 5000 mcg | — | |
| Pantothenic Aid (as D-Calcium Pantothenate) | 50 mg | — | |
| Calcium (as Tricalcium Phosphate) | 80 mg | — | |
| Phosphorus (as Tricalcium Phosphate) | 40 mg | — | |
| Proprietary Blend | 720 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
Ingredient amounts are hidden inside a blend
The panel lists “Proprietary Blend” as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.
Exact trademark owner identified
USPTO lists Gurin Products, LLC (['LIMITED LIABILITY COMPANY', 'LIMITED LIABILITY COMPANY']) in ['CALIFORNIA, USA', 'WASHINGTON, USA'] for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itself prove who manufactures or sells this product.
No data yet: Testing claimed — documentation not found
The listing claims third-party testing without naming any lab or certifier, so the claim can't be verified as stated.
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.
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.
UPC valid, no independent record
Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.
180-day review-count history is on file
Exact-listing history records written-review counts from 573 on 2026-01-23 to 668 on 2026-07-21 (net +95). 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 |
|---|---|---|
| Quality-testing claim “…r Men and Women – Nails and Skin, USA Made - Third Party Tested, B1, B2, B3, B6, B7 Complex - 60 Capsules Bi…” | Claimed, not verifiable We looked for: a named laboratory, a certificate of analysis, or a certification-registry entry | No named laboratory, no certificate of analysis, and no certification-registry entry matching this product was located. |
| Manufacturing claim “…& Natural Radiance* MADE IN USA GLUTEN FREE GMP CERTIFIED NON GMO DYES FREE PEANUTS FREE SUG…” | Claimed, not verifiable We looked for: the facility registration or certificate behind the claim | Facility-level claims can be accurate and still say nothing about this product’s contents. No registration document was located. |
| Origin claim “…imen while sticking to your dietary efforts. Made In USA! Third Party Tested - At Vitboost, quality i…” | Claimed, not verifiable We looked for: customs records or label filings showing where ingredients were sourced and where it was made | “Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product. |
| Benefit claim “…also help strengthen hair at the root which improves strength, reduces breakage and split ends, a…” | Not assessed 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 assessed — 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.
