I have acid reflux and as a result poor diet and I feel like I'm low on potassium. How to supplement/foods to eat to raise it?

Low potassium? Before you start to add supplement (s)(s) to raise your potassium (k) level, make sure that it is low. If it's not, you are wasting your money on a s you do not need. Have your blood taken by a physician to see if your k is, in fact, low before you make your own diagnosis that may be incorrect. Good luck.
