I've been increasing my potassium intake with low-sodium V-8 juice. Eating fruits and vegetables will give you more potassium, but hold back on including sodium with that. There's lots of hidden (and not-so-hidden) salt in almost everything! Sunsweet Prunes are my recent favorite snack - lots of fiber and potassium without sodium (Bite size prunes). Even a fresh raw apple has fiber, potassium, and just a smidgin of natural sodium.
You want to increase potassium, calcium and magnesium levels - where? In your blood? A doctor would tell you if those levels were low, after testing your blood. In your diet, there are foods that are rich in each of those things (see nutritiondata.self.com, and use the 'nutrient search' tool from the drop down tools menu) but you are also working within a framework of daily calories. Do you take a daily multivitamin with minerals included?
