I am a CKD 3 patient with a GFR of <35, currently under excellent care. I have been stable for over 5 years now. I recently had updated labs and was found to have a potassium of 5.2. I was told to go by my "low potassium food list." However, I am having problems with the nutrition facts for foods that I purchase. Some of them do not even list potassium. I would like to know my maximum potassium mg or grams per day. I have been trying to ask my nephrologist and his staff/nutritionist but am having difficulty getting in touch with them this time of year. Can you give me an idea of how much potassium is too much?
