“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.

Ingredient evidence exists; on dose: label states 275 mg/serving — about 65% 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.
