What the interaction means

Metformin's FDA label mentions magnesium only as 'magnesium stearate,' an inactive tablet ingredient, not an interaction statement. Magnesium's own established interactions-section record does not name metformin.

No documented interaction between Magnesium and Metformin was identified in the authoritative sources reviewed. This is not a guarantee that no interaction exists for every dose, formulation, or individual -- it means the sources checked did not document one.

Practical context

Both substances' current sources were checked (magnesium via its existing verified catalog record; see the source note above on a transient fetch block); the inactive-ingredient mention was deliberately not treated as a real interaction claim.
