Checks outIs the label honest?

Every ingredient shows its amount · 1 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.

Checks outWho is behind it?

The barcode identity checks out · 898440001790.

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 “Ubiquinol Extra Strength, 200 mg” (variant: 60ct) — identity confirmed across retailer listings.

What remains open 2
  • No matched to this exact product public label filing is saved in this record.
  • Barcode checksum is valid; no independent product record was found.

These are evidence gaps, not strikes against the product.
