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.

Registry receipt: FDA enforcement search · Natrol ↗
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.…”

CheckedWho is behind it?

The barcode identity checks out · 047469083496.

The barcode matches, so we are checking the right product rather than a look-alike.

Evidence and sources

UPCitemdb resolves 047469083496 to "Natrol Sleep & Restore Capsules for Restorative Sleep with Magnesium, GABA, 5mg " (Natrol) — consistent with this listing.

CheckedCan you trust the review pattern?

We can see 22 of this product’s 203 reviews — the count rose between December 1, 2025 and August 22, 2026. That is too small a slice to say anything about the wider pattern.

A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.

Evidence and sources

Written reviews rose from 181 to 203 between December 1, 2025 and August 22, 2026. The largest rise inside any single 30-day window was about 10, so the count moved in steps rather than in one burst.

Only one exact price was available at build time; prices change by date, seller, and promotion.

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 100 mg. 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.
