Does the marketing hold up?

Every ingredient shows its amount · 3 ingredients listed. Every ingredient shows its real amount — nothing is hidden in a proprietary blend.

“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.

?Couldn’t verify independently2

“TESTED”

No named laboratory or lot-specific certificate was found for this exact product. The exact brand page repeats a testing claim but names no issuer. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.

Evidence →
“in the USA from globally sourced ingredients, each serving (1 capsule) provides 1,500mcg of Vitamin A, 125mcg of Vitamin D3, and 500mcg of Vitamin”

“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.

CheckedIs the label honest?

Every ingredient shows its amount · 3 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.

CheckedWho is behind it?

The barcode identity checks out · 850059700020.

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 “ADK Vitamin Supplement - High Potency Vitamin A, D3, K2 (MK-7) for Bone, Heart, and Cholesterol Support, 60 Capsules (2 Month-Supply)” (variant: Default Title) — identity confirmed across retailer listings.

Locked evidence record →Open the full source-linked finding
What remains open 2
  • No FDA recall matched this brand in the current search.
  • We have not found a public label filing for this exact product.

These are evidence gaps, not strikes against the product.
