I'm not taking magnesium now, I was taking it 4 months ago, and when I checked the levels 3 months ago, it was ok.
I also read about potassium, and I was thinking to supplement it by myself. But then I saw that unlikely B!2, high potassium can have side effects.
Last time I checked it 3 months ago it was ok, but that was before starting with b12 supplements. I'm trying to find some vegetarian or vegan neurologist, because all of the other doctors don't take me seriously
