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.

Marketing claims, checked

The checks, one by one

The public sources did not settle the marketing promises on this label.

Partly confirmed1

“and immune health support supplement: contains one 60 count bottle of Nature Made Magnesium Complex with D3 and Zinc Capsules for a 30-day”

Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.

Evidence →

Ingredient research can support context, but it is not a trial of this exact product.

?Couldn’t verify independently1

“1 Pharmacist Recommended Vitamin & Supplement Brand*; made in the USA with quality global”

“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.

Evidence →

We looked and found no public proof. That does not count against the product.

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”. …

Needs explanationIs the label honest?

Niacin: 50 mg on the label; adult upper limit 35 mg.

This serving is about 1.4× the adult upper limit shown by NIH. The limit applies to supplemental/added niacin, adults.

Evidence and sources

The panel lists 50 mg niacin. NIH gives 35 mg as the adult Tolerable Upper Intake Level for supplemental/added niacin, adults. That is about 1.4 times the limit.

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 · 031604002596.

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

Evidence and sources

Open Food Facts resolves 031604002596 to "Magnesium Complex" (Nature Made) — consistent with this listing.

Research behind the findings

Dose and research context

We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.

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 230 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits inside 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.

The panel lists 10 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits inside that range.

0studied 8 mg–40 mg

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