Checked against public sources on August 6, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Registered owner records: PROEMPIRE LIMITED LIABILITY COMPANY · Proempire LLC. The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
“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 2 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.
For best result!
Headlines first. Open evidence only when you want the source trail.

USPTO returned multiple live supplement-class records for the exact brand wordmark: PROEMPIRE LIMITED LIABILITY COMPANY, Proempire LLC. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
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.
Locked evidence record →Open the full source-linked findingThe barcode matches, so we are checking the right product rather than a look-alike.
UPCitemdb resolves 810078475569 to "Vitamatic Melatonin 10 mg with Magnesium 200 mg 120 Tablets - High Potency Sleep" (Vitamatic) — consistent with this listing.
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 43 to 45 between July 1 and July 16, 2026. The largest rise inside any single 30-day window was about 2, so the count moved in steps rather than in one burst.

These are the USPTO records behind the brand name. We show them all rather than choosing one by similarity.

This answers who owns registrations for the brand wordmark. It does not by itself prove which entity made, imported, or sold this specific product. 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 200 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.
The panel lists 10 mg of melatonin per serving. Studies we found used 0.5 mg–5 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.
