Regulated heartbeat: Potassium enables your heart to beat in a healthy way. So, if you have rhythm problems, potassium may be key. Your doctor can advise you on that. A check might be part of your routine doctor visits.
How Much Do You Need?
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.
Some diuretics for heart failure can make you lose potassium in your pee. If you are taking one, have your levels checked. If yours are low, you can raise them by taking a supplement or eating more potassium-rich foods.
