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. 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”. …

Public contextWho is behind it?

Registered owner records: PHARMAVITE LLC · PHARMAVITE CORPORATION

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: PHARMAVITE LLC, PHARMAVITE CORPORATION. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.

CheckedWho is behind it?

The barcode identity checks out · 031604028183.

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

Evidence and sources

The brand's store lists this exact barcode as “Vitamin D3 2000 IU (50 mcg) Tablets” (variant: 400) — identity confirmed across retailer listings.

What remains open 2
  • Panel amounts still need a clearer source image.
  • We have not found a public label filing for this exact product.

These are evidence gaps, not strikes against the product.
