clean up the rest of your diet, if needs be. make sure your potassium intake is adequate. elevated levels in those two tests would bolster your low B12 results, but ,the normal doesn't negate. Several week, ,to months to see sig. results. Think a week of shots might be a good idea, BUT, again, clean up your diet, (if needed) and get plenty of potassium! Have you had a BMP done? That would be a basic metabolic panel; just want to make sure your potassium is not already high.....it has a fairly narrow range, don't want to go overboard. Good luck!
