Sandhu'S Magnesium Glycinate with Quercetin Capsules
Checked against public sources on July 25, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
The barcode identity checks out · 812239001129. The barcode matches, so we are checking the right product rather than a look-alike.
“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
1 promise checks out. 4 could not be fully confirmed from public sources.
✓Checks out1
◐Partly confirmed3
“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.
A testing body is named on the listing, but we found no lot-specific certificate of analysis.
Ingredient evidence exists; on dose: label states 72 mg/serving — about 17% 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.
?Couldn’t verify independently1
“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
We looked and found no public proof. That does not count against the product.
