Proprietary Blend publishes one combined total, not its individual ingredient doses.
Rebuilt from public sources on July 22, 2026 · evidence availability is not a safety or effectiveness verdict.
The panel lists “Proprietary Blend” as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.

The listing-image panel publishes 12 separately quantified rows and 1 combined blend total. Ingredients inside a blend do not have separate amounts.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Proprietary Blend | 720 mg | — | |
| Calcium (as Tricalcium Phosphate) | 80 mg | — | |
| Pantothenic Aid (as D-Calcium Pantothenate) | 50 mg | — | |
| Phosphorus (as Tricalcium Phosphate) | 40 mg | — | |
| Thiamin (as Thiamine HCL) | 5 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; the open question is whether those declared amounts are independently verified and how they compare with relevant research.

This is the USPTO owner of the brand wordmark. It tells a shopper who is behind the brand, but does not by itself identify the manufacturer or prove where this product was made.
Review counts rose gradually. Written-review counts rose from 573 to 668 across the observed period. That describes count movement, not review authenticity or product quality. A variation family may share some public counts.

These links provide the public research context used alongside the captured panel. They do not establish safety, effectiveness, or product quality.
Can the testing claim be tied to a named laboratory and this product lot? Evidence that would settle it: lot-specific COA naming the laboratory and matching the product lot.
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
USPTO lists Gurin Products, LLC (['LIMITED LIABILITY COMPANY', 'LIMITED LIABILITY COMPANY']) in ['CALIFORNIA, USA', 'WASHINGTON, USA'] for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itself prove who manufactures or sells this product.
Documented concerns
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
The listing claims third-party testing without naming any lab or certifier, so the claim can't be verified as stated.
We read the full Supplement Facts panel from the listing-image panel (below), but the label doesn’t state a serving weight, so the arithmetic can’t run. A gap in the label’s information, not evidence of a problem.
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
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.
Exact-listing history records written-review counts from 573 on 2026-01-23 to 668 on 2026-07-21 (net +95). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.
What to ask and check
Ask the brand or seller
Can you send the certificate of analysis (COA) for the lot number on my bottle?
A real COA names the testing laboratory, the test date, the lot it covers, and what was measured. “Third-party tested” with no document behind it is a marketing sentence.
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.
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.
What is the amount of each ingredient inside the proprietary blend?
A blend total tells you nothing about whether any single ingredient reaches a dose used in research. Brands may decline — that answer is informative too.
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
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.
Scan the barcode on the package and confirm it reads 810053630181.
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.
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.
