Hey there!! I have very low potassium myself. I take four prescribed potassium supplements every day and it is still low. Yes, I take half of a fluid pill daily, but four potassium pills per day should help!! I also have VERY low D and B levels.

I have wondered if it was from RSD (have had it 20 or 21 years), or some malabsorption problem.

Would be curious to see if others with RSD have this issue.
