Potassium is an essential mineral needed to regulate water balance, levels of acidity, blood pressure, and neuromuscular function. This mineral also plays a critical role in the transmission of electrical impulses in the heart.
Reliable and relatively consistent scientific data showing a substantial health benefit.
Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
| Used for | Amount | Why |
|---|---|---|
Hypertension in People Not Taking Potassium-Sparing Diuretics | 2,400 mg per under a doctor's supervision | Potassium is effective at lowering blood pressure, according to an analysis of 33 trials. |

| Used for | Amount | Why |
|---|---|---|
Cardiac Arrhythmia | 1,000 mg daily under medical supervision | In one study, people taking hydrochlorothiazide for high blood pressure saw a significant reduction in arrhythmias when they supplemented with potassium. |

| Used for | Amount | Why |
|---|---|---|
Chronic Fatigue Syndrome (Magnesium Aspartate) | 1 gram of aspartates is taken twice per day | Potassium-magnesium aspartate has shown benefits for chronically fatigued people in some trials. |

| Used for | Amount | Why |
|---|---|---|
Congestive Heart Failure | Consult a qualified healthcare practitioner | Potassium can be beneficial for heart patients, but talk to your doctor first. Several drugs for CHF may cause potassium retention, making extra potassium dangerous. |

The best way to obtain extra potassium is to eat several pieces of fruit per day, as well as liberal amounts of vegetables. The amount of potassium found in the diet ranges from about 2.5 grams to about 5.8 grams per day. The amount allowed in supplements—99 mg per tablet or capsule—is very low, considering that one banana can contain 500 mg. Check with your physician before taking large amounts of potassium since it may irritate the stomach.
Most fruits are excellent sources of potassium. Beans, milk, and vegetables contain significant amounts of potassium.
So-called primitive diets provided much greater levels of potassium than modern diets, which may provide too little. Gross deficiencies, however, are rare except in cases of prolonged vomiting, diarrhea, or use of “potassium-depleting” diuretic drugs. People taking one of these drugs are often advised by their doctor to take supplemental potassium. Prescription amounts of potassium provide more than the amounts sold over the counter but not more than the amount found in several pieces of fruit.
