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.
This recall is not about the product on this page. Pharmavite recalled a different product on June 6, 2016. FDA has since closed that case. The recalled item was “Nature Made(R) D3 1000IU, 125 count, UPC 0-31604-02793-3”. …
USPTO returned multiple live supplement-class records for the exact brand wordmark: PHARMAVITE LLC, PHARMAVITE CORPORATION. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
We can see 14 of this product’s 65 reviews — the count rose between September 26, 2025 and August 23, 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 51 to 65 between September 26, 2025 and August 23, 2026. The largest rise inside any single 30-day window was about 5, so the count moved in steps rather than in one burst.
These are the USPTO records behind the brand name. We show them all rather than choosing one by similarity.

Buying options
Where you can check or buy it
Open related seller leads before buying, then confirm the flavor, count, and serving size. Their prices are visible, but LookCloser does not claim savings until the pages share a UPC/GTIN.
Related brand page publishes 4.0/5 across 42 reviews
The related page's review pool may differ from the observed listing. Because the page does not publish a matching UPC/GTIN, LookCloser does not attribute that review aggregate to this exact sellable unit.
Prices and stock are point-in-time observations. Related pages are never used as product evidence. No affiliate links; LookCloser earns nothing from these sellers.
