Nature Made Magnesium Oxide 250 mg Tablets (100 Tablets)

SuppCheckr Score77/100

SuppCheckr score uses the magnesium scoring profile (Phase 4D-3). Key drivers: clear oxide form, 250 mg elemental magnesium per tablet, and lowest observed price per 100 mg elemental in this cluster — offset by unknown USP/testing verification, multiple tablet excipients, Target-sourced label, and oxide GI caveats. Oxide value framing uses elemental mg and dated price only — not absorption superiority or dismissal of the form.
