Potassium. Get it from coconut water, bananas, spuds (all varieties), some tomato juices, and most vegetables. Do not waste your time or money on potassium supplements, they are typically a very, very low dose, not to mention unnatural and potentially dangerous. Also your high dose of magnesium supplementation is hard on the digestive pipes and unbalances (or displaces) some other minerals.

Discover which REAL foods are high in minerals (mostly fresh produce and carnivorous fare) and eat well. Sweet dreams.
