Does the marketing hold up?
Registered owner records: Viviscal Limited · OY VIVIPHARMA AB. The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
“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.

Headlines first. Open evidence only when you want the source trail.
The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
USPTO returned multiple live supplement-class records for the exact brand wordmark: Viviscal Limited, OY VIVIPHARMA AB. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
Locked evidence record →Open the full source-linked findingEvery ingredient shows its real amount — nothing is hidden in a proprietary blend.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Locked evidence record →Open the full source-linked findingThese are evidence gaps, not strikes against the product.
These are the USPTO records behind the brand name. We show them all rather than choosing one by similarity.

This answers who owns registrations for the brand wordmark. It does not by itself prove which entity made, imported, or sold this specific product. Open USPTO source ↗
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.
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 15 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.
