Does the marketing hold up?

Every ingredient shows its amount · 2 ingredients listed. Every ingredient shows its real amount — nothing is hidden in a proprietary blend.

“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.

Marketing claims, checked

The checks, one by one

The public sources did not settle the marketing promises on this label.

Partly confirmed2

“& Sleep: Organic lemon balm extract interacts with GABA receptors to support relaxation and soothe the central nervous system to support deep…”

Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.

Evidence →
“in facilities using GMP (Good Manufacturing Practice)”

“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.

Evidence →

Ingredient research can support context, but it is not a trial of this exact product.

?Couldn’t verify independently1

“in”

“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.

Evidence →

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.

CheckedIs the label honest?

Every ingredient shows its amount · 2 ingredients listed.

Every ingredient shows its real amount — nothing is hidden in a proprietary blend.

Evidence and sources

The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

CheckedWho is behind it?

The barcode identity checks out · 850060296697.

The barcode matches, so we are checking the right product rather than a look-alike.

Evidence and sources

The brand's store lists this exact barcode as “Relax: Magnesium Complex” (variant: Default Title) — identity confirmed across retailer listings.

What remains open 4
  • No FDA recall matched this brand in the current search.
  • We have not found a public label filing for this exact product.
  • Barcode checksum is valid; no independent product record was found.
  • No dated review-history series is on file yet.

These are evidence gaps, not strikes against the product.

Research behind the findings

Dose and research context

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.

Background reading

What the research says about these amounts

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 120 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits below that range.

0studied 200 mg–420 mg

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
