Checked against public sources on August 5, 2026 · LookCloser does not sell or recommend supplements.
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”. …
Locked evidence record →Open the full source-linked findingNiacin: 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.

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