Potassium is a mineral that helps prevent heart problems, lowers high blood pressure, and maintains normal functioning of the muscles, brain and nerves. On the other hand, potassium deficiency or hypokalemia causes abnormal heart rhythm, muscle weakness, constipation and muscle cramps.
An adult requires about 4,700 milligrams of potassium per day to maintain good health. In addition to eating potassium-rich foods, another alternative for obtaining sufficient potassium intake is to take potassium supplements.
Some medications can raise the levels of potassium in the body, whereas others may lower these levels. For example, spironolactone, a drug that treats edema and high blood pressure, raises potassium levels, whereas some diuretics for heart disease can make the body lose potassium. Factors such as hormones and kidney function can also affect the levels of potassium in the body.Learn more about Nutritional Content
