How Much Do You Need?
How much potassium should you eat? 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.
Most people shouldn't have any problems from eating a high-potassium diet or taking potassium supplements as directed. If you have kidney failure or other kidney problems, check with your doctor about how much potassium you should get.
Some diuretics for heart failure can make you lose potassium in your urine. If you are taking a diuretic, it's important to have your potassium levels checked, and repleted as needed. You can put it back by taking a supplement or eating more potassium-rich foods.
