Checked against public sources between July 26 and September 2, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
The barcode identity checks out · 016500535362. The barcode matches, so we are checking the right product rather than a look-alike.
“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.

We read 8 lines from the package photograph. It is our transcript of the label, not the manufacturer’s panel, and it may be incomplete.
The public sources did not settle the marketing promises on this label.
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.
Headlines first. Open evidence only when you want the source trail.

Locked evidence record →Open the full source-linked findingA count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Written reviews rose from 898 to 979 between August 8, 2025 and July 6, 2026. The largest rise inside any single 30-day window was about 13, so the count moved in steps rather than in one burst.
Locked evidence record →Open the full source-linked findingThese are evidence gaps, not strikes against the product.
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 6 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits below that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
