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.

“VITBOOST Magnesium Glycinate 500mg - Support Sleep 120 Veggie Capsules MAGNESIUM”
Evidence →Ingredient evidence exists; on dose: label states 90 mg/serving — about 21% of the adult daily reference (adult RDA 310–420 mg elemental; NIH sets 350 mg/day as the supplemental upper level for elemental magnesium). A single serving isn’t meant to supply a full day, so this is context, not a shortfall. Caveat: chelate labels (glycinate, citrate) often state compound mass, which reads ~5–7× higher than elemental magnesium — the Supplement Facts panel settles which is meant.
Ingredient research can support context, but it is not a trial of this exact product.

“VEGAN, NON-GMO, 3RD PARTY TESTED, MADE IN USA: Just Magnesium Glycinate Chelate,”
Evidence →“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
“and everyday wellness. VEGAN, NON-GMO, 3RD PARTY TESTED, MADE IN USA: Just Magnesium Glycinate”
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.

Checks outIs the label honest?
Listing claim matches the Supplement Facts panel
The label promise and the Supplement Facts amount agree.
Evidence and sources
The listing claims 90 mg; the photo-read Supplement Facts panel shows Magnesium at 90 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
