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-image panel publishes an amount for each of its 8 listed rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin C (Non-Acidic) (as IMMUNE N PLUS® Calcium Ascorbate) | 500 mg | — | |
| Vitamin D3 (as Cholecalciferol) | 125 mcg | — | |
| Vitamin K2 (as MK-7 Natural Bacillus Subtilis Natto) | 100 mcg | — | |
| Zinc (as Zinc Bisglycinate Chelate) (Albion®) | 50 mg | — | |
| Selenium (as Selenium Glycinate) (Albion®) | 150 mcg | — | |
| Copper (as Copper Bisglycinate Chelate) (Albion®) | 3 mg | — | |
| Quercetin (20:1 extract of Sophora Japonica Flower, offering an equivalent of 1,000mg of powder) | 1,000 mg | — | |
| NAC (as N-Acetyl-L-Cysteine) | 600 mg | — |
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; the open question is whether those listed amounts are independently verified and how they compare with relevant research.
vision:claude-cli:subscription Amounts are shown as listed panel data, not independently lab-tested contents.
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 #272740 “Immune C Plus 12 in 1 Advanced Complex” (KAPPA NUTRITION), entered 2022-07-21, with the full Supplement Facts on file. Company on file: Manufacturer — Kappa Nutrition, Frisco, Tx.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
USPTO lists Mando International LLC (LIMITED LIABILITY COMPANY) in TEXAS, 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.
Written reviews rose from 15 to 36 between September 21, 2025 and July 11, 2026. The largest rise inside any single 30-day window was about 4, 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.
The panel lists 125 mcg vitamin d. NIH gives 100 mcg as the adult Tolerable Upper Intake Level for adults; 100 mcg = 4,000 IU. That is about 1.2 times the limit.
The panel lists 50 mg zinc. NIH gives 40 mg as the adult Tolerable Upper Intake Level for adults, from all sources. That is about 1.2 times the limit.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
The observed listing claims third-party testing without naming a lab or certifier. No product-bound report is saved, so the claim cannot be verified as stated. NSF, IFOS, USP, and Informed-Sport were not checked in this record.
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.
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.
This means only that no enforcement record matched the brand name — it does not mean the product was tested, reviewed, or cleared by FDA. New and untested products also have no recall records.
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 14 on 2025-08-28 to 36 on 2026-07-11 (net +22). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.
What to ask and check
Ask the brand or seller
Can you send the certificate of analysis (COA) for the lot number on my bottle?
A real COA names the testing laboratory, the test date, the lot it covers, and what was measured. “Third-party tested” with no document behind it is a marketing sentence.
Where are the ingredients sourced, and where is the product manufactured?
“Made in USA” can describe only the final bottling step. Ask which country the actives came from and whether the facility is audited.
Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.
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 850053522543.
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 |
|---|---|---|
| Quality-testing claim “…PREMIUM QUALITY YOU CAN TRUST Manufactured in a cGMP Certified Facility, third-party tested for quality, made with premium ingredients, Non-GMO, Gluten-Free, Kosher Ingr” | Claimed, not verifiable We looked for: the observed listing, saved brand product page, any linked COA or test report; NSF, IFOS, USP, Informed-Sport were not queried | No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur. |
| Origin claim “…PREMIUM QUALITY YOU CAN TRUST Manufactured in a cGMP Certified Facility, third-party tested for quality, made with premium ingredients, Non-GMO, Gluten-Free, Kosher Ingr” | 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 “…COMPLETE 15 IN 1 IMMUNE SUPPORT FORMULA IMMUNE N PLUS combines 15 carefully selected ingredients including Non-Acidic Vitamin C (Calcium Ascorbate), NAC, Quercetin 20:1,” | 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. 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
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Zinc (as Zinc Bisglycinate Chelate) (Albion® | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 50 mg — above 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.
