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.
The listing amount and panel row need explanation
We compared the listing claim (500 mg) with the panel row (1 g quercetin). They do not match within the report tolerance; the source label or serving basis needs checking.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Quercetin | 1000 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; any remaining comparison concerns the front-label framing.
vision:google/gemini-flash-1.5 Amounts are shown as declared panel data, not independently lab-tested contents.
Every check we ran
Each ingredient’s amount is disclosed
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Exact trademark owner identified
USPTO lists Sandhu Products, Inc. (CORPORATION) in CALIFORNIA, 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.
UPC independently corroborated
UPCitemdb resolves 012239000645 to "Sandhu s Quercetin Dietary Supplement for Respiratory Health 1000mg per Servin" (SANDHU S) — consistent with this listing.
Testing claim names a recognized certifier
A named certifier/laboratory appears in the listing (registry cross-check pending).
No data yet: Label math could not be verified
The retained listing evidence does not establish net weight, per-serving dose, servings per container, so the dose claim cannot yet be checked against serving arithmetic. This is a neutral evidence gap, not a pass or strike.
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 482 on 2026-02-03 to 501 on 2026-07-12 (net +19). 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 “…onoid supplement. NSF-CERTIFIED, THIRD-PARTY LAB TESTED FOR PURITY & POTENCY: Manufactured in an NSF…” | Partly supported We looked for: a named laboratory, a certificate of analysis, or a certification-registry entry | A testing body is named on the listing, but no lot-specific certificate of analysis was located. |
| Manufacturing claim “…rty lab testing to ensure purity & potency.* GMP QUALITY CERTIFIED THIRD PARTY LAB TESTED MAN…” | 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 “…GMP QUALITY CERTIFIED THIRD PARTY LAB TESTED MANUFACTURED IN USA WITH GLOBALLY SOURCE Third Party Tested Rese…” | 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 “…| 1000mg Per Serving of 2 Capsules | Immune Support Supplements For Respiratory, Cellular Health…” | 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.

Where it sells
A brand storefront was found, but no exact-product price was published or identity-bound at build time.
Brand store sandhus.com: 52 supplement products (+40 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.
Reference links for identification only — LookCloser has no affiliate relationships and earns nothing from any link on this page.
Ingredient science
No knowledge-base entry yet for this formula's active ingredients — entries are added as the KB grows. Absence of a science card is a coverage gap, not a judgment.
