The last time my magnesium levels were in the normal range on hair analysis was in 1998, just before I started crashing. Ever since, on hair analysis, they've been quite low, not even been close to the normal range, despite taking a pretty good dose (in the form of magnesium glycinate the last several years, but other forms prior to them) And, I think I'm at bowel tolerance. I tried increasing the dose a couple of days ago, and well, won't do that again. However, on an Exatest last year, which measures intracellular magnesium levels, my number was well within the normal range, a little above the median. Sarah Myhill recommended magnesium injections some 4-1/2 years ago, but my doctor wouldn't order them. I was thinking of finding another doctor to do it, but now wonder if the injections would be a good thing or not. My guess is maybe I'm having trouble utilizing the magnesium in my body? So though I have enough of it I can't use it, and injections just may not be a good idea? It's a puzzlement - any ideas would be appreciated!
