Does the marketing hold up?

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.

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. Natrol, LLC recalled a different product on April 8, 2021. FDA has since closed that case. The recalled item was “Natrol Melatonin 3 mg, Tab 60 White bottle with purple flip-top cap.…”

Public contextWho is behind it?

Registered owner records: NATROL, INC. · Natrol, Inc. · Natrol LLC

The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.

Evidence and sources

USPTO returned multiple live supplement-class records for the exact brand wordmark: NATROL, INC., Natrol, Inc., Natrol LLC. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.

CheckedIs the label honest?

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.

What remains open 2
  • We have not found a public label filing for this exact product.
  • Barcode checksum is valid; no independent product record was found.

These are evidence gaps, not strikes against the product.

Who owns the brand wordmark?

Same UPC/GTIN observed across 2 sellers. Amazon was lowest at $9.09; iHerb was highest at $9.52 — a $0.43 range at check time.

The brand-page price is shown as a shopping lead only. It is excluded from the exact-product price difference because the page does not publish this record's matching UPC/GTIN.

The observed listing and related brand page repeat 10000 mcg. That confirms cross-page consistency of the published claim, not the product contents.

Reference prices only · no affiliate links · every compared seller must publish the matching UPC/GTIN.
