Hello everyone, I am new here and was hoping that someone here would be able to offer insight into a peculiar problem I have been facing. About 7 months ago I started taking a bunch of supplements (mostly the MAG protocol + licorice root and probiotics) and was starting to feel a lot better. After 2 months I got what I believed to be the stomach flu, and didn't take anything for a few days. I had an appointment with my doctor, and she expressed concern about how much magnesium I was taking (around 800-1000mg a day) and I decided to take a break on the supplements and see where I was at. I was feeling ok, but after a few weeks wanted to start adding a few things back in, like magnesium. I quickly found out I can no longer tolerate magnesium in any somewhat significant amount. I can get away with some trace minerals drops in water, but anything else (even NUUN tabs with 25mg of mag oxide) causes me big trouble. The symptoms I experience are hypoglycemia, shakiness, anxiety, lowered blood pressure (sometimes leading to orthostatic hypotension), and excessive urination. I've asked my doctor what she thinks, and she just shrugs it off. I am curious as to why this may have changed for me. It makes me hesitant to take anything else at this point because of how awful I feel taking magnesium now. Is it common for people with AF to not be able to tolerate magnesium? I can't find much information about it searching the web.
