Potassium plays a role in every heartbeat. A hundred thousand times a day, it helps trigger your heart to squeeze blood through your body.
It also helps your muscles to move, your nerves to work, and your kidneys to filter blood
The U.S. Department of Agriculture recommends 4,700 milligrams per day for healthy people. The easiest way to get this amount is by adding high-potassium fruits and vegetables to your diet.
It's possible to get too much of a good thing, though. Ask your doctor before starting a potassium supplement.
If you have kidney failure or other kidney problems, talk with your doctor about how much potassium you should get.
