Potassium, a mineral and electrolyte, is essential for your cells, tissues, and organs to function properly. It plays a vital role in heart health, digestive, and muscular function, bone health, and more.
While potassium is found in many foods commonly consumed in the US – including fruits, vegetables, dairy products, salmon, sardines, and nuts – only 2 percent of US adults get the recommended daily amount of 4,700 milligrams (mg).1
This is especially problematic because potassium is a nutrient that needs to be kept in proper balance with sodium in your blood. If you consume too much sodium, which is common if you eat a lot of processed foods, you’ll have an increased need for potassium.
