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.

“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

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 · 031604026745.

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: 220) — 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.

Same UPC/GTIN observed across 3 sellers. Amazon was lowest at $13.78; Brand website was highest at $18.39 — a $4.61 range at check time.

The observed listing and exact brand page repeat 50 mcg. That confirms cross-page consistency of the published claim, not the product contents.

Review pages

Does the brand page tell the same story?

Brand page 4.40/5 · retailer 4.7/5inspect

The exact brand page is lower by 0.30 points. The brand page publishes 68; the retailer surface shows 26,310. Different systems can collect different review pools, so this is a signal to inspect, not proof that reviews were manipulated.

The brand page did not expose a complete star-by-star breakdown in the captured structured data, so LookCloser cannot test whether lower-star reviews were omitted. Source: exact barcode-bound brand product page · retailer surface · counts do not prove authenticity.
