Checked against public sources on August 11, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Ingredient amounts are hidden inside “Elemental Magnesium Complex (From 1230 mg of Magnesium Propr”. The panel lists “Elemental Magnesium Complex (From 1230 mg of Magnesium Propr” (280 mg) as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.
“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 3 lines from the package photograph. It is our transcript of the label, not the manufacturer’s panel, and it may be incomplete.
1 promise needs a closer look.
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.
We found no named, citable study of this product or formula. The claim may rest on ingredient research rather than a trial of this product.
No named laboratory or lot-specific certificate was found for this exact product. The exact brand page names no testing issuer and links no product-bound report. Under NSF/ANSI 173, NSF lists Smarter Nutrition Inc. products, including Smarter Nutrition Smarter Curcumin with Black Seed Oil Softgels, but not this exact SKU. 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.
“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.
Headlines first. Open evidence only when you want the source trail.
The barcode matches, so we are checking the right product rather than a look-alike.
The brand's store lists this exact barcode as “Smarter Magnesium Stress & Sleep Formula - Tablets” (variant: 1 Bottle) — identity confirmed across retailer listings.

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 280 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits inside that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
