FDA recall appears in this brand's history
An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
Evidence and sources
Brand-level context only, not a finding about this product. Pharmavite recalled a different or not-exactly-bound product on 2016-06-06: “Specific lots of Nature Made(R) Vitamin D tablets may exceed specifications for yeast/mold.” (status: Terminated). The recalled product was: “N…

The outside identifier points to this product, so the other checks are less likely to be about a look-alike.

Confirmed evidence
What checked out02
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Found on the brand's own store
The brand's store lists this exact barcode as “Zero Sugar Vitamin D3 Gummies” (variant: 110) — identity confirmed across retailer listings.
Barcode confirmed in an outside database
Open Food Facts resolves 031604004040 to "ZERO Sugar D3 Gummies" (Nature Made) — consistent with this listing.
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.
FDA recall appears in this brand's history
Brand-level context only, not a finding about this product. Pharmavite recalled a different or not-exactly-bound product on 2016-06-06: “Specific lots of Nature Made(R) Vitamin D tablets may exceed specifications for yeast/mold.” (status: Terminated). The recalled product was: “Nature Made(R) D3 1000IU, 125 count, UPC 0-31604-02793-3” — not necessarily the product on this page. Verify at FDA’s recall database.
Public label filing not retained
This record does not currently hold an identity-bound public label filing for the exact product. That is a LookCloser coverage gap, 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 232 on 2026-01-30 to 267 on 2026-06-23 (net +35). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
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.
4
Where are the ingredients sourced, and where is the product manufactured?
“Made in USA” can describe only the final bottling step. Ask which country the actives came from and whether the facility is audited.
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 031604004040.
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.
