How Do You Monitor Calcium-Potassium-Magnesium Balance? I am currently slogging my way through the B-12 - The Hidden Story thread. I just came to the following, posted by Freddd: One has to watch that calcium-potassium-magnesium balance. It can get out of whack so easily. For me it fluctuates and causes problems. Each time I get things stable for a while, something changes and I have to redo the balancing. It does change because of the healing itself too. I am waiting to start increasing my B12 until my potassium comes up above barely detectable. I am doing hair tissue mineral analysis through a clinical dietitian. How and how often do you monitor your mineral levels and ratios? While I'm writing, should I be making any changes to my supplements until the K is up? I tried to get L-Carnitine Fumerate instead of Acetyl-L-Carnitine last week, but my health food store was out. Could the fumerate increase the activity of the methlyB12 that I am currently taking and cause a decrease in K?
