Potassium Intake Recommendations

The recommended daily intakes for potassium in Europe are in the order of 3.1–3.5 grams (g) per day for adults (24).

The U.S. Food and Nutrition Board has established an adequate intake level (AI) for potassium in milligrams (mg) per day based on intake levels that have been found to lower blood pressure, reduce salt sensitivity, and minimize the risk of kidney stones (25).
