Magnesium deficiency can cause Potassium deficiency. Trying to fix Potassiun alone wont work because Magnesium is required to absorb it, or something like that; can't remember the full details now. And obviously if your symptoms are actually from a Potassium deficiency, trying to fix Magnesium alone won't work either, if you're still not getting enough Potassium. So, your best bet is magnesium supplements and lots of bananas :p
