ah yes, unbalanced vitamin D / Magnesium intake.
I took about 5000 iu vitamin D for about 2 years (I was real serious about preventing my MS from getting worse.) And that clever move left me quite deficient in Magnesium, but the doctors told me that my Magnesium was fine because they had given me a serum magnesium test and the results were "normal."
They didn't even think to test me for Mg: I had to ask them. But, back then, I believed that a result from a lab test that was "normal" meant that things were all good. How did I get so ignorant? Anyway, I've done a lot of research on magnesium over the past year or so and it has become painfully obvious to me that, if a serum Magnesium test comes back "normal," it means nothing other than the amount in the blood is normal. The other 99% of the Magnesium in the body is intracellular (inside of tissue cells such as muscle and bone cells.) The body will readily take Mg from tissues or filter out excess Mg through the kidneys to keep the level in the blood in the proper range.

Early this year I got the Idea that maybe the vitamin D was what was keeping me from getting over the Mg deficiency that I had been taking lots of Mg for during the last several months. So I quit the vitamin D and in the next week things (primarily muscle spasms) got better. Then I took 2000 iu of vitamin D and it put me right back to where I was a week earlier. So no more vitamin D for me until this Mg problem clears up. I sure don't need vitamin D using up Mg in its conversion from inactive to active form.
Currently I take 400 mg of Albion Chelated TRS Magnesium on an empty stomach
3-4 times per day
and I soak my feet in Mg Chloride solution (5 cups of flakes/1 gallon water) for 2-4 hours per day.
I get no ill effects from this high level of Mg, I only feel better from it and worse when I don't do it.
I also take: 200 mcg - SeMSC Selenium / day
108mg - Benfotiamine / day
to help with cell retention and absorption.
Overall my symptoms have been slowly (too slowly) getting better.
My last serum Mg test:
Component Standard Range Your Value
MAGNESIUM 1.3 - 2.0 mEq/L 1.8
What else can I do to improve my Mg status ??
