What the interaction means

Folate's NIH ODS fact sheets name five interacting medications -- methotrexate, phenytoin, carbamazepine, valproate, and sulfasalazine -- and magnesium is not among them. The NIH Office of Dietary Supplements' magnesium fact sheet does not mention folate or folic acid.

No documented interaction between Folate / Folic Acid and Magnesium 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

Folate's NIH ODS fact sheets and magnesium's NIH ODS fact sheet were checked directly, full text, in both directions. Folate's own named interacting medications do not include magnesium or minerals generally.
