I have found that because I have Fibro I have had to up my potassium supplementing to 1000 mg a day.

I felt great at first but then started having fatigue, muscle weakness and cramping again. This is a classic case of hypokalemia . Low blood potassium..So if you start to feel an aggrevation of your fibro symptoms you might consider upping your potassium intake.

I take liquid K and Mortons no salt.........1/4 tsp of the no salt gives me 650 a day.

I was getting swelling around my knees and in my feet and that is clearing up now.
