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

2declared rows
2separately quantified
0combined blend totals

The listing-image panel publishes an amount for each of its 2 declared rows. That supports ingredient-by-ingredient review; it does not verify the contents.

Panel rowAmount%DVWhat to notice
Iodine (as Potassium Iodide)10,000 mcg
Selenium (as Selenomethionine)40 mcg

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, servings per container, so the dose claim cannot yet be checked against serving arithmetic. This is a neutral evidence gap, not a pass or strike.

i

Not found in NIH's DSLD label registry

The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.

i

Brand holds NSF/ANSI 173 certification (brand-level)

Designs for Health appears in NSF’s certified-products registry with 10 certified product(s), but we couldn’t confirm this exact listing is among them. Certification covers contents and contaminants — not effectiveness.

i

UPC valid, no independent record

Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.

i

180-day review-count history is on file

Exact-listing history records written-review counts from 49 on 2026-02-28 to 55 on 2026-07-12 (net +6). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.

i

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.

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.
ClaimStatusWhat we found
Professional-endorsement claim
“…B complex with bioactive methylation support #1 RECOMMENDED BY FUNCTIONAL MEDICINE PR GMP NSF”
Marketing credential
We looked for: who the professionals are, whether they were compensated, and what the endorsement covers
A professional endorsement is a marketing credential, not clinical evidence. Public sources don’t establish who was consulted, whether they were paid, or what specifically they reviewed.
Manufacturing claim
“…ort #1 RECOMMENDED BY FUNCTIONAL MEDICINE PR GMP NSF”
Claimed, not verifiable
We looked for: the facility registration or certificate behind the claim
Facility-level claims can be accurate and still say nothing about this product’s contents. No registration document was located.
Benefit claim
“…um (Selenomethionine) Supplement for Thyroid Support - Non-GMO + Gluten-Free (120 Capsules) High…”
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.
