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
This recall is not about the product on this page. Pure Encapsulations, Inc. recalled a different product on November 17, 2017. FDA has since closed that case. The recalled item was “Pure Encapsulations Systemic Enzyme Complex DIETARY SUPPLEMENT 180 CAPSULES UPC: 7 66298 00862…”

Every ingredient shows its amount · 1 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 findingCheckedWho is behind it?
The barcode identity checks out · 766298001890.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
Open Food Facts resolves 766298001890 to "NAC" (Pure Encapsulations) — consistent with this listing.
Locked evidence record →Open the full source-linked findingCheckedCan you trust the review pattern?
Reviews rose from 152 to 229 between August 13, 2025 and August 27, 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 152 to 229 between August 13, 2025 and August 27, 2026. The largest rise inside any single 30-day window was about 11, so the count moved in steps rather than in one burst.
