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.
The 100 mg hyaluronic acid claim matches the panel
We did the comparison: the listing claims 100 mg of hyaluronic acid, and the listing-image panel shows 100 mg hyaluronic acid serving size 1 veg capsule. Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Sodium (from Sodium Hyaluronate) | 10 mg | — | |
| Hyaluronic Acid | 100 mg | — | |
| L-Proline (Free-Form) | 100 mg | — | |
| Alpha Lipoic Acid | 50 mg | — | |
| Grape Seed Extract (Vitis vinifera) (Standardized for Polyphenols) | 25 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; any remaining comparison concerns the front-label framing.
vision:google/gemini-flash-1.5 Amounts are shown as declared panel data, not independently lab-tested contents.
Every check we ran
UPC independently corroborated
Open Food Facts resolves 733739031518 to "Hyaluronic Acid Double Strength 100mg" (Now) — consistent with this listing.
Multi-ingredient formula — panel read, serving weight unknown
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.
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.
FDA recall appears in this brand's history
Brand-level context only, not a finding about this product. Now Foods recalled a different or not-exactly-bound product on 2025-05-08: “regular yeast was inadvertently packaged as nutritional yeast” (status: Terminated). The recalled product was: “NOW Nutritional Yeast Powder, Nt. Wt. 10oz. UPC 7 33739 02460 2” — not necessarily the product on this page. Verify at FDA’s recall database.
No exact supplement trademark owner found
The live USPTO search returned no exact-wordmark supplement-related registration for this brand. That is a public-record gap, not evidence that the brand has no owner or that the product is improper.
180-day review-count history is on file
Exact-listing history records written-review counts from 624 on 2026-01-23 to 637 on 2026-07-20 (net +13). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
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?
| Claim | Status | What we found |
|---|---|---|
| Manufacturing claim “…en, Dairy Free, Egg Free, Kosher, Low Sodium GMP Quality Assured: NPA A-rated GMP certificati…” | 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 “…d Grape Seed Extract, 120 Veg Capsules JOINT SUPPORT*/IMPORTANT JOINT LUBRICANT*: Take 1 NOW Hyal…” | 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.

No knowledge-base entry yet for this formula's active ingredients — entries are added as the KB grows. Absence of a science card is a coverage gap, not a judgment.
