Potassium Contributions by ColleenO

The most common use of potassium supplements is to make up for potassium depletion caused by diuretic drugs. By depleting the body of potassium, some diuretics can cause or worsen arrythmias.

Potassium is one of the major electrolytes in your body, along with sodium and chloride. Potassium and sodium work together like a molecular seesaw: when the level of one goes up, the other goes down. All together, these three dissolved minerals play an intimate chemical role in every function of your body.

When used by physicians, potassium is usually measured according to meqs (milliequivalents) rather than the more common mg (milligrams). A typical therapeutic dosage of potassium is between 10 and 20 meq, taken 3 to 4 times daily.

Potassium is an essential mineral that we get from many common foods. Bananas, orange juice, potatoes, avocados, lima beans, cantaloupes, peaches, tomatoes, flounder, salmon, and cod all contain more than 300 mg of potassium per serving. Other good sources include chicken, meat, and various other fruits, vegetables, and fish.

Over-the-counter potassium supplements typically contain 99 mg of potassium per tablet. There is some evidence that, of the different forms of potassium supplements, potassium citrate may be most helpful for those with high blood pressure.¹

Research indicates that it is important to get enough magnesium, too, when you are taking potassium.^2,3,4 It might be wise to take extra vitamin B12 as well.⁵

Diuretic drugs in the thiazide family tend to deplete the body of the minerals potassium and magnesium. People using such drugs are usually advised to take potassium supplements because potassium deficiency can cause arrhythmias.

In addition to the deficiency issue, it is probably healthy to take in at least five times as much potassium as sodium (and perhaps 50 to 100 times as much). However, the standard American diet contains twice as much sodium as potassium. Therefore, taking extra potassium may be a good idea in order to balance the sodium we consume to such excess.

Evidence suggests that potassium supplements may be most effective for people who eat too much salt.¹³
