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

Brand-level context only, not a finding about this product. Pharmavite recalled a different or not-exactly-bound product on 2016-06-06: “Specific lots of Nature Made(R) Vitamin D tablets may exceed specifications for yeast/mold.” (status: Terminated). The recalled product was: “N…

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.

Checks outIs the label honest?

Every ingredient shows its amount · 5 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.

Checks outWho is behind it?

The barcode identity checks out · 031604002527.

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 “High Absorption Magnesium Glycinate Gummies” (variant: 40) — identity confirmed across retailer listings.

Research behind the findings

Dose and research context

The label amount is shown beside the ranges used in the linked ingredient studies.

Background reading

What the research says about these amounts

Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.

The panel lists 100 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits below that range.

0studied 200 mg–420 mg

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.

Same UPC/GTIN observed across 3 sellers. Amazon was lowest at $12.98; Brand website was highest at $20.99 — a $8.01 range at check time.

The observed listing and exact brand page repeat 100 mg. That confirms cross-page consistency of the published claim, not the product contents.
