Checked against public sources on August 14, 2026 · LookCloser does not sell or recommend supplements.

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 10 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.

This recall is not about the product on this page. Jarrow Formulas Inc recalled a different product on January 15, 2018. FDA has since closed that case. The recalled item was “Jarrow Formulas Liquid L-Carnitine; 16 fl oz.…”
Locked evidence record →Open the full source-linked findingEvery ingredient shows its real amount — nothing is hidden in a proprietary blend.

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 167 mg of magnesium per serving. Studies we found used 200 mg–420 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.
The panel lists 1 mg of boron per serving. Studies we found used 3 mg–10 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.
The panel lists 3 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.
