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
The 50 mg zinc (as zinc picolinate) claim matches the panel
MARKETING50 mg — per-serving claim
PANELZinc (as zinc picolinate) 50 mg — same amount
matches panelWe did the comparison: the listing claims 50 mg of zinc (as zinc picolinate), and the listing-image panel shows 50 mg zinc (as zinc picolinate) 1 capsule. Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Zinc (as zinc picolinate) | 50mg 455% | — |
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
What checked out3
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 eSupplements, LLC (LIMITED LIABILITY COMPANY) in UTAH, 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.
Barcode confirmed in an outside database
Open Food Facts resolves 810139573005 to "Zinc Picolinate" (Nutricost) — consistent with this listing.
Documented concerns
What needs caution1
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Dose claim implausibly high for a capsule
Claimed zinc 50.0 mg is 100% of the ≈50 mg serving (serving size on the label, keyed to UPC 810139573005) — above what gummy matrices realistically carry.
Unresolved public record
What is still missing7
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Listing claim matches the label panel
The listing claims 50 mg; the photo-read Supplement Facts panel shows Zinc (as zinc picolinate) at 50 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
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.
Zinc amount, in daily-intake context
label states 50 mg/serving — about 125% of the adult daily reference (adult RDA 8–11 mg; NIH sets 40 mg/day as the tolerable upper limit for adults). A single serving isn’t meant to supply a full day, so this is context, not a shortfall. Caveat: chelate and gluconate labels may state compound mass rather than elemental zinc. Sources: NIH ODS — Zinc fact sheet, PubMed search: zinc supplementation trial.
Public label filing not saved
We have not found a public label filing for this exact product. That is a gap in our records, not evidence that no filing exists.
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.
180-day review-count history is on file
Exact-listing history records written-review counts from 423 on 2025-08-01 to 492 on 2026-08-17 (net +69). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
Package and trademark records name different responsible entitie
The package says manufactured for: nutricosť, 351 E 1750 N, Vineyard, UT 84059. USPTO names eSupplements, LLC 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
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
Scan the barcode on the package and confirm it reads 810139573005.
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.
3
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 “…THIRD PARTY TESTED…” | Partly supported We looked for: the observed listing, saved brand product page, any linked COA or test report; NSF, IFOS, USP, Informed-Sport were not queried | A testing body is named on the listing, but we found no lot-specific certificate of analysis. |
| Manufacturing claim “…240 Vegetarian Caps Per Bottle 50 mg of Zinc (from Zinc Picolinate) Per Serving 240 Servings of Zinc Picolinate Per Bottle Non-GMO and Gluten Free Manufactured in an NSF” | Partly supported We looked for: the facility registration or certificate behind the claim | “GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check. |
“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 | 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.
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 nutricost.com: 199 supplement products (+51 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.
