Pure Magnesium Glycinate 400mg Serving

Checked against public sources on July 26, 2026 · LookCloser does not sell or recommend supplements.

180capsules · 60 servings

Does the marketing hold up?

The listing and related brand page both say it is tested, but neither names the lab. A related brand page repeats the marketing claim, but its UPC is not published and repetition is not independent testing evidence. A named issuer and lot-specific report would make it checkable.

Trouble on record?No recalls found

“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

“HEALTH & BONE SUPPORT - Doctors know best, magnesium glycinate is one of the gentlest supplements on the”

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

Evidence →
“supplement is made in the USA in a GMP compliant facility and independently lab verified and tested for”

“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 independently2

“supplement is made in the USA in a GMP compliant facility and independently lab verified and tested for”

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

Evidence →
“tested for”

No named laboratory or lot-specific certificate was found for this exact product. A related brand page repeats a testing claim but names no issuer; its UPC is not published. NSF, 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.

Evidence →

We looked and found no public proof. That does not count against the product.

What is worth knowing.

Headlines first. Open evidence only when you want the source trail.

What remains open 6
  • No FDA recall matched this brand in the current search.
  • Panel amounts still need a clearer source image.
  • 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.
  • Brand ownership is not settled in this record.

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.

Only one exact price was available at build time; prices change by date, seller, and promotion.

The brand-page price is shown as a shopping lead only. It is excluded from the exact-product price difference because the page does not publish this record's matching UPC/GTIN.

The observed listing and related brand page repeat 400 mg. That confirms cross-page consistency of the published claim, not the product contents.

Reference prices only · no affiliate links · every compared seller must publish the matching UPC/GTIN.
