Shannan is entirely incorrect, that is way too low. 4.7g is the recommended dosage, and more is recommended for athletes. Potassium is an essential electrolyte. 4.7g = 4700mg. It is difficult to overdose on potassium, but you do generally want to keep a balance of your minerals. Studies show that potassium can help negate the consequences of a high sodium diet, and higher your ratio of potassium to sodium is, the better your cardiovascular system will be for it.
