What the interaction means

NCCIH's bodybuilding-supplements page (which covers creatine) mentions vitamin B12 only as a generic dietary-supplement example in unrelated nutrition advice, not a creatine-specific interaction claim. The NIH ODS vitamin B12 fact sheet's interactions section names only gastric acid inhibitors and metformin -- creatine is not named.

No documented interaction between Creatine and Vitamin B12 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' own current authoritative sources were checked directly; the generic dietary-advice mention was deliberately not treated as a real interaction claim.
