Every ingredient 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.

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.
Panel, decoded
What the label discloses
6listed rows
6separately quantified
0combined blend totals
The listing-image panel publishes an amount for each of its 6 listed rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin C (as ascorbic acid) | 500 mg | — | |
| Zinc (as zinc picolinate) | 12.5 mg | — | |
| Zinc (as zinc citrate) | 12.5 mg | — | |
| Zinc (as zinc glycinate) | 12.5 mg | — | |
| Zinc (as zinc gluconate) | 12.5 mg | — | |
| Quercetin | 500 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
What checked out2
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
Exact trademark owner identified
USPTO lists DPL Trading, 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.
Documented concerns
What needs caution1
These are documented contradictions or claims that need more evidence. They are separate from missing data.
The label’s 50 mg reads 4× larger than the zinc on the panel
Salt weight, not the actual mineral. 50 mg is the weight of the zinc picolinate compound. The actual zinc in it is 12 mg. You are getting 12 mg of zinc per serving.
Unresolved public record
What is still missing6
We looked for these signals but could not settle them from public sources. A gap is not a strike.
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.
“Lab tested” claimed, but no lab or report named
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.
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.
No recall found — which is not the same as being tested
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.
Package and trademark records name different responsible entitie
The package says distributed by: Micro Ingredients, 4382 Mission Blvd, Montclair, CA 91763. USPTO names DPL Trading, Inc. as the exact wordmark owner. That can be a normal distributor, manufacturer, or licensing relationship; the saved records do not establish the relationship.
What to ask and check
What would settle the open questions
Why is this shown?
Everything we couldn’t verify is something a person can still ask about. Rather than leave gaps sitting as dead ends, we turn each one into a specific question — the exact document, citation, or number that would settle it — plus the things you can confirm yourself with the bottle in your hand.
Ask the brand or seller
1
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.
2
What is the product’s UPC or GTIN?
The barcode is how a product gets matched to outside records — certification registries, label databases, recall data. Without it, almost nothing can be cross-checked.
3
Is this label filed with NIH’s Dietary Supplement Label Database (DSLD)?
Filing is voluntary, so absence proves nothing — but a filed label puts the full ingredient table on public record where anyone can read it.
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
1
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.
2
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
Why is this shown?
A listing’s promises are the reason people buy. Each one gets its own row: what was promised, what evidence would settle it, and what we could actually find. We never call a claim false — only whether proof proportionate to it exists on the public record.
| Claim | Status | What we found |
|---|---|---|
| Quality-testing claim “…Lab Tested…” | 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. |
“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?
An ingredient can be well-studied at one amount and barely studied at the amount in your bottle. This lines the label up against the doses researchers actually used. It answers ‘are these the same numbers?’ — never ‘should you take this?’
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Zinc (as zinc picolinate) | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 12.5 mg — within 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.

Where it sells
We found a brand storefront, but we could not match any price on it to this exact product when we checked.
Brand store www.microingredients.com: 163 supplement products (+87 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.
