My potassium level is 5.2 and am taking K bind powder 3 times a week for about 3 years. Have been maintaining low potassium diet as best as I can. My kidney functions are normal. My creatinine is .6. What could be the Problem? I am a diabetic for 40 years under insulin. I often suffer from constipation, but am in reasonably good health. Will K bind cause side effects. I am almost 82 years of age.
