   MgO is almost always referred to as the lousiest form (least absorbable) of   
   dietary magnesium.   
   Yet, the product is simply MgCl2 + H20, with a substantially neg delta H.   
      
   So how could it be worse (less absorbable) than MgCl2?   
      
   Along those lines, virtually all forms of Mg are salts of acids, including   
   malate, citrate (carboxylic acids, in these cases), so why would ANY form of   
   magnesium be preferable to another?
