I recently read an article about Mg deficiency and  migraines.  Have you 
had your nieces Magnesium levels  checked?  The best way for this is 
intracellular, but you could  start with serum.  Tho the body everything it can 
to 
keep the blood  balanced, to the disadvantage of the cells.  It's done just 
like a  DNA swab under the tongue.  If you like I will look up the lab I  did 
this  with.
