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 2 listed rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Zinc (as Zinc L-Methionine Sulfate) | 15 mg | — | |
| Copper (as Gluconate) | 1 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:google/gemini-2.5-flash 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 #50700 “Mineral Balance” (Jarrow Formulas), entered 2015-09-25, with the full Supplement Facts on file. NIH marks this label as off-market (superseded or discontinued version). Company on file: Distributor — Jarrow Formulas, Los Angeles, CA.
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 Jarrow Formulas, 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.
Written reviews rose from 549 to 551 between June 9 and July 21, 2026. The largest rise inside any single 30-day window was about 1, 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 400 mg magnesium. NIH gives 350 mg as the adult Tolerable Upper Intake Level for SUPPLEMENTAL magnesium only (not from food). That is about 1.1 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 saved listing evidence does not establish net weight, per-serving dose, so the dose claim cannot yet be checked against serving arithmetic. This is a neutral evidence gap, not a pass or strike.
Published sources describe how magnesium, 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 — Magnesium fact sheet, PubMed search: magnesium glycinate supplementation.
label states 15 mg/serving — about 38% 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.
This recall is not about the product on this page. Jarrow Formulas Inc recalled a different product on January 15, 2018. FDA has since closed that case. The recalled item was “Jarrow Formulas Liquid L-Carnitine; 16 fl oz. (475 ml) bottle, dietary supplement; product number 102006; UPC 7 90011 02006 6; Vitamin B5 10 mg; L-Carnitine 1000 mg; Other i”. FDA recorded the reason as “A higher than normal micro result was found at the six month time point for one lot of Liquid L-Carnitine”. Verify at FDA’s recall database.
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 548 on 2026-05-26 to 551 on 2026-07-21 (net +3). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
Open Food Facts resolves 790011130086 to "Zinc Balance" (brand not supplied), but that record lacks enough exact brand/product detail to confirm or contradict this listing.
What to ask and check
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 790011130086.
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 |
|---|---|---|
| Benefit claim “Jarrow Formulas Zinc Balance 15 mg - 100 Servings (Veggie Caps) - Zinc with Copper - Essential Minerals for Immune System Support - Immune Support Supplement - Gluten Fre” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Ingredient evidence exists; on dose: label states 15 mg/serving — about 38% 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. |
“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 |
|---|---|---|
| Magnesium | shaded = doses used in studies (200 mg–420 mg) · bar = this label | 400 mg — within the studied range |
| Zinc (as Zinc L-Methionine Sulfate) | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 15 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
