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 named ingredient is not separately quantified
The panel was read, but it does not give a separate amount for msm. The listing claim cannot be compared to a named panel row.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Methylsulfonylmethane | 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.
No data yet: Label math could not be verified
The retained 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.
FDA recall appears in this brand's history
Brand-level context only, not a finding about this product. Jarrow Formulas Inc recalled a different or not-exactly-bound product on 2018-01-15: “A higher than normal micro result was found at the six month time point for one lot of Liquid L-Carnitine.” (status: Terminated). The recalled product 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” — not necessarily the product on this page.

180-day review-count history is on file
Exact-listing history records written-review counts from 387 on 2026-03-02 to 384 on 2026-06-24 (net -3). 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.
The headline amount is not tied to a same-name panel row
The listing presents 1,000 mg for msm, but vision:google/gemini-flash-1.5 does not contain a same-name quantified row. The retained image read may be incomplete, so this is a specific question to resolve rather than a contradiction.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Benefit claim “…hane - Source of Sulfur - Dietary Supplement Supports & Strengthens Joints - Up to 200 Servings MS…” | 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.
Verifiability profile — 1 of 6 public signals
What this listing gives the public to check. Publishing these signals doesn't prove quality — but withholding them means claims can only be taken on faith.
