We need potassium for the proper functioning of many major organ systems; it is essential for the heart, kidneys, muscles, nerves, and digestive system to operate normally. Potassium is also required for regulating fluid balance, the body’s acid-base balance, and blood pressure. In addition, considerable scientific evidence suggests that a diet providing at least 4.7 grams of potassium daily lowers the risk of stroke, high blood pressure, osteoporosis, and kidney stones and that a diet rich in fruits and vegetables, which are among the best sources of potassium, is associated with a reduced risk of cardiovascular disease.

Which form of potassium is best for augmenting food intake? At health food stores, I find potassium in many forms—gluconate, chloride, aspartate, chelate, etcetera—but no one can tell me if one is better assimilated or useful than another.
