Sodium and potassium work in opposition of each other. When your potassium level is low your body retains sodium and water which can increase your blood pressure. If you increase your potassium intake in your diet you will excrete more sodium and water and this leads to a decrease in your blood pressure. Recent studies have shown that most adults are eating too much salt (sodium) and not enough potassium. The daily recommended amount of potassium for adults is 4,700 mg per day. We do not recommend potassium supplements or pills (unless you discuss this with your healthcare provider first) but encourage people to eat foods that are rich in potassium.
