Where it sells

Prices found, with identity limits shown

A brand storefront was found, but no exact-product comparison could be completed.

Walmart and iHerb require an exact UPC/GTIN match before their price, panel, or reviews can be attached. Product-name results are treated only as leads, never as this product. No affiliate links; LookCloser earns nothing from these sellers.

Shopper scorecard

The useful findings, in decision order.

Only product facts and comparisons earn a card. Pipeline gaps stay collapsed.

What remains open 2
  • Not yet in NIH's public label registry.
  • Barcode checksum is valid; no independent product record was found.

These are evidence gaps, not strikes against the product.

Relevant research · quick links

Read the ingredient evidence directly

The Supplement Facts panel is not captured here, so these links provide ingredient-level context only; they do not verify this product’s contents.

What would settle the biggest open question?

Do the labeled amounts reconcile with the stated serving and container? Evidence that would settle it: identity-bound Supplement Facts panel.

Confirmed evidence

What checked out00

These checks found support in the public record. They confirm specific facts, not the product as a whole.

Nothing could be independently confirmed from the available record.

Documented concerns

What needs caution00

These are documented contradictions or claims that need more evidence. They are separate from missing data.

No contradictions or product-specific cautions were found at this check depth.

Unresolved public record

What is still missing05

We looked for these signals but could not settle them from public sources. A gap is not a strike.

The listing doesn't publish enough to check the math

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.

No data

No label filed with NIH's public catalog

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

No data

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.

No data

180-day review-count history is on file

Exact-listing history records written-review counts from 0 on 2026-06-04 to 19 on 2026-07-05 (net +19). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.

No data

UPC valid, no independent record

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

No data

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

Which specific study supports this claim — and was it run on this exact formula?

Ask for the citation, how many people took part, the dose used, and whether the study tested this product or just one ingredient in it. Ingredient research is not product evidence.

2

Can you send a clear photo of the full Supplement Facts panel?

It’s the one part of the label required to state what’s inside and how much. A seller who won’t show it before purchase is asking for trust the label would have earned.

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

Scan the barcode on the package and confirm it reads 022600978220.

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.

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.
