In brief: May be true

Oral potassium supplement is linked to interfere with B12 absorption, if that happens , it is recommended that vitamin B12 be given in the form of injection.

In brief: Potassium and B12

The answer to your question is "yes".
Vitamin B12 can cause a temporary drop in the level of potassium in the blood. This is a concern for people who are receiving vitamin B12 as treatment for a condition called megaloblastic anemia. People taking vitamin B12 should be monitored to make sure their potassium levels aren’t going too low.
