What is the potential importance of taking potassium?

While potassium is lower in modern diets compared with so-called primitive diets, true deficiencies are uncommon.Some, though not all, research suggests that raising potassium intake may help prevent high blood pressure. Other research suggests higher potassium intake may help prevent stroke. However, the maximum amount of supplemental potassium allowed in one pill (99 mg) is far below the recommended amounts (at least 2,400 mg per day). Multiple potassium pills should not be taken in an attempt to get a higher amount, since they can irritate the stomach. The best way to get extra potassium is to eat several servings per day of fruits, vegetables, or their juices.
