research has indicated that the general population is low in mag and that ms patients have even lower mag status to begin with, as well as associated spasticity.
of course if you were to add an unbalanced d3 regimen to that particular picture, you'd logically be asking for trouble and you could expect to see a worsening of symptoms related to low mag status (including one or more of the many possible manifestations of spasticity).
as i've said before, for whatever reason i happened to take mag and calcium with my d3 right from day one - but by taking a small amount, of what turned out to be a relatively insoluble inorganic form, and taking it at the same time as the d3, i ended up with some pretty unpleasant deficiency symptoms. followed, as you may recall, by a raft of very unpleasant magnesium side effects over time, while figuring out the best supplementation form, dose and timing.
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
