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
The 1 g vitamin c (as ascorbic acid & sodium ascorbate) claim matches the panel
MARKETING1 g — per-serving claim
PANELVitamin C (as Ascorbic Acid & Sodium Ascorbate) 1 g — same amountAdded Sugars 7 g
matches panelWe did the comparison: the listing claims 1 g of vitamin c (as ascorbic acid & sodium ascorbate), and the listing-image panel shows 1 g vitamin c (as ascorbic acid & sodium ascorbate) 4 gummies. Those amounts agree. This is internal consistency, not independent lab testing.

Mass check · assumptions shown
18 g listed contents = 7 g major actives + 11 g carbohydrate
Assume 4 pectin gummies × 2.5–3.5 g each = 10–14 g serving. That leaves roughly 0–2 g for water, pectin, sweetener, acid, and flavor. Serving weight is not printed, so this is a warning, not a closed impossibility.
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; any remaining comparison concerns the front-label framing.

These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
Barcode confirmed in an outside database
UPCitemdb resolves 031604003708 to "Nature Made Maximum Strength Dosage Vitamin C Gummies 1000mg per Serving - Tange" (Nature Made) — consistent with this listing.
Every ingredient 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.
Documented concerns
What needs caution1
These are documented contradictions or claims that need more evidence. They are separate from missing data.
The label says 18 g of vitamin c in 4 gummies — but not what tho
A serving is 4 gummies, and the panel lists 18,000 mg — 18 g — of vitamin c in that serving. What the panel doesn’t give is the one number needed to check it: what a serving weighs. Gummies of this type usually run somewhere around 2.5 to 3.5 grams each, which would put 4 of them near 10 to 14 grams. If that holds here, vitamin c would be a high share of the serving’s weight, and that is why we stopped on this number. But we did not weigh these gummies. The 2.5–3.5 gram figure is a general estimate for the format, not a measurement of this product. One published number would settle it: the weight of one gummy, or of a 4-gummy serving. Until then we can’t confirm the 18 g and we can’t dispute it. Nothing here says the product is short — only that the label doesn’t let anyone check. Checked September 3, 2026.
Unresolved public record
What is still missing6
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Multiple USPTO brand-owner records are shown
USPTO returned multiple live supplement-class records for the exact brand wordmark: PHARMAVITE LLC, PHARMAVITE CORPORATION. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
Listing claim matches the label panel
The listing claims 1 g; the photo-read Supplement Facts panel shows Vitamin C (as Ascorbic Acid & Sodium Ascorbate) at 1 g per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
FDA recall appears in this brand's history
This recall is not about the product on this page. Pharmavite recalled a different product on June 6, 2016. FDA has since closed that case. The recalled item was “Nature Made(R) D3 1000IU, 125 count, UPC 0-31604-02793-3”. FDA recorded the reason as “Specific lots of Nature Made(R) Vitamin D tablets may exceed specifications for yeast/mold”. Verify at FDA’s recall database.
Public label filing not saved
We have not found a public label filing for this exact product. That is a gap in our records, 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 245 on 2025-12-31 to 327 on 2026-08-20 (net +82). 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
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.
2
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
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.
2
Scan the barcode on the package and confirm it reads 031604003708.
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.
3
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
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.
| Claim | Status | What we found |
|---|---|---|
| Origin claim “…MADE IN THE USA WITH GLOBAL INGREDIENTS…” | Claimed, not verifiable We looked for: customs records or label filings showing where ingredients were sourced and where it was made | “Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product. |
| Benefit claim “Nature Made Maximum Strength Dosage Vitamin C 1000mg per Serving, Adult Vitamin C Immune Support Gummies, 80 Gummies for Daily Immune Support, 20 Day Supply…” | Not checked yet 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 checked yet — 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.
