Checked against public sources on July 31, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
FDA recall appears in this brand's history. An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
“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 4 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.
“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.
Ingredient research can support context, but it is not a trial of this exact product.
“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
We looked and found no public proof. That does not count against the product.

An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
This recall is not about the product on this page. Health & Wellness Center, Inc. recalled a different product on September 24, 2021. FDA has since closed that case. The recalled item was “Dr. Berg Nutritionals, Liquid Vitamin D with Zinc Dietary Supplement ( Liquid Vitamin D )…”
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.

USPTO identifies the public owner or applicant behind this brand wordmark. This does not by itself identify the product manufacturer or prove where the product was made. 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 60 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits above that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
