The supplements that I’m familiar with contain 99mg of potassium per tablet, which is 3% of your RDA. Only one single tablet per day is recommended. Potassium is a relatively abundant nutrient in all kind of food and thus is relatively difficult to get too little of it. How can one tablet of 3% RDA make much of a difference?

Also, while I more or less understand that there may not be a specific relationship between quantities of sodium and potassium in a person’s diet as each nutrient should be looked at on its own, a diet low in sodium and "high" in potassium is said to be beneficial for the blood pressure and heart. Do those two nutrients balance each other? Can you counteract a diet that’s too high in sodium by increasing your potassium intake?

Thanks!
I also vaguely remember something about a sodium and/or potassium pump or channel in the wall of certain (maybe all?) cells.
