“CERTIFIED GOOD MANUFACTURING”
Evidence →“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.

Magnesium Glycinate 1,000 mg Capsules – Chelated High Absorption…

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.

Is it the real thing?✓Barcode matches outside records
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.

“Magnesium Glycinate 1000mg Capsules – Chelated High Absorption Magnesium to Support Relaxation, Stress Relief & Muscle Comfort – Vegan, Non-GMO – 120”
Evidence →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.
?Couldn’t verify independently1
“PARTY”
Evidence →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.
We looked and found no public proof. That does not count against the 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 1 g of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits above 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.
