“Potassium supplement is not a good idea. You should get your potassium from foods...”
I agree. The most potassium available in an otc supplement is around 100 mg. Perhaps you can get much more from a prescription supplement but there is no comparison with what is available from real, (not processed) food.
Check out this food table. The RDA for potassium is around 5,000 mg/day. In order to increase your potassium intake you must also avoid processed foods that are saturated with sodium. Sodium and potassium are antagonistic with each other. It doesn't help to get your 5,000 mg of potassium if you are also getting 6,000 mg of sodium.
This is one time when I agree with some others here that supplements, with only 100 mg of potassium, are a waste of time in comparison with getting your nutrition from real food.
