What the interaction means

Vitamin B12's own established interactions-section record names only gastric acid inhibitors and metformin -- potassium is not named.

No documented interaction between Potassium 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

Potassium's own NIH fact sheet could not be independently re-confirmed for this specific pair in this research pass (a transient access block on ods.od.nih.gov affected this session's fetch attempts) -- this record is based on the B12 side only, which is why it is rated low rather than moderate evidence quality. A future pass should re-verify potassium's own fact sheet directly before this can be upgraded.
