Potassium is necessary for the body because it helps to control fluid levels in cells and body. It also plays a role in transmitting chemical messages from the nerve cells to contract muscles. It also helps the eyes be able to function, and it helps with digestion.
If you get too much potassium in your body it can cause nausea, slow pulse, and sudden collapsing.

If you do not have enough potassium in your body, you get a disease known as hypokalemia. This causes symptoms such as fatigue, muscle weakness, constipation, abdominal pain, and intestinal paralysis..

You can buy a potassium supplement at your local pharmacy, it is called potassium gluconate. The average cost for a daily supplement is about 2 cents.
