Reply To: I recently fell and broke my hip. While I was in the hospital, my blood test showed 5.1 potassium levels and my creatine was elevated. The doctor was very concerned about kidney failure and wanted to take drastic measures. When I stopped taking my vitamin D3 for a couple of weeks, the blood levels returned to high normal. When I started back up, the levels began to elevate again. My vitamin was at 38. My question is what is the correlation between vitamin d3 and potassium and creatine. Is the elevation something to be concerned about or can it be ignored. Any information would be greatly appreciated.
