Potassium came up the other day in a recipe post and I found this today. It is kind of basic, but gives those who are considering taking potassium some things to consider.

Q: Why do we need potassium? What foods — other than bananas — are good sources of potassium?
— Susan, Florida
Dr. Caroline Apovian
A: Potassium is needed to transport ions between cells — this is a major factor in metabolism and keeping your heart pumping the way it should. If you take medications that "waste" potassium, like diuretics (water pills), your body will excrete potassium in the urine. If this is the case, you need to make sure that you get enough postassium through your diet or take a potassium supplement. If you don't like bananas, don't worry, there is potassium in most fruits and vegetables.
A balanced diet — including potassium-rich fruits and vegetables — can guard against low potassium levels. For athletes who work out to exhaustion, it is sometimes important to take potassium supplements along with a salt replacement and drink a lot of water. However, for those who exercise moderately, a potassium replacement is probably not necessary.
