Does the marketing hold up?

Registered owner records: NATURE'S BOUNTY, INC. · NATURE'S BOUNTY (NY), INC. · Société des Produits Nestlé S.A. (société anonyme (sa); SWITZERLAND). The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.

Who’s behind it?USPTO lists 3 owner recordssame brand name, more than one registrant — we don’t choose between them
Is it the real thing?No barcode publishedso it can’t be matched against certification, recall or other retailer records
Trouble on record?No recalls found

“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.

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

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

Claimed without support found1

“HEALTH: As a component of the enzyme collagenese, Zinc has been clinically studied for its contribution to skin health”

We found no named, citable study of this product or formula. The claim may rest on ingredient research rather than a trial of this product.

Research behind the findings

Dose and research context

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

Dose vs research

Zinc

50 mg per serving — above the 8–40 mg/day used in the linked studies.

Linked ingredient research · label amount, not a recommendation
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 50 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits above 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.
