Does the marketing hold up?
Listing claim matches the Supplement Facts panel. The label promise and the Supplement Facts amount agree.
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

Listing claim matches the Supplement Facts panel
The label promise and the Supplement Facts amount agree.
Evidence and sources
The listing claims 65 mg; the photo-read Supplement Facts panel shows Iron (as ferrous sulfate) at 65 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
Locked evidence record →Open the full source-linked findingEvery ingredient shows its amount · 2 ingredients listed.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Locked evidence record →Open the full source-linked findingThe barcode identity checks out · 380513000774.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
UPCitemdb resolves 380513000774 to "Puregen Ferrous Sulfate 325 mg. 65 mg. Elemental Iron. 200 Tablets" (Puregen Labs) — consistent with this listing.
Locked evidence record →Open the full source-linked findingReviews rose from 187 to 299 between August 2, 2025 and August 26, 2026 — no sudden jump.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 187 to 299 between August 2, 2025 and August 26, 2026. The largest rise inside any single 30-day window was about 17, so the count moved in steps rather than in one burst.
