What the interaction means

Vitamin C's NIH fact sheet states its only documented medication-interaction concerns are with radiation therapy, chemotherapeutic agents, and statins; it does not mention magnesium. This project's existing published content on magnesium, drawn from magnesium's own authoritative sources, does not document an interaction with vitamin C or ascorbic acid either.

No documented interaction 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

Vitamin C's own current authoritative fact sheet was checked directly, in full. This catalog's existing sourced content for magnesium was also checked for any mention of vitamin C or ascorbic acid; none was found.
