Magnesium Glycinate 500mg

Checked against public sources on July 25, 2026 · LookCloser does not sell or recommend supplements.

Does the marketing hold up?

The observed listing says it is tested, but names no lab or certifier. A testing badge without an issuer or report is a marketing claim, not evidence. Ask for the lab name and lot-specific report.

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.

The checks, one by one

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

Partly confirmed1

“USA with globally sourced ingredients in GMP-certified facilities and third-party lab”

“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

“GMP-certified facilities and third-party lab tested for purity and quality. Made without”

No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. 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 →
“if pregnant or nursing. PREMIUM QUALITY – made in USA with globally sourced ingredients 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.
