Magnesium Deficiency

note:  CVS Pharmacy ONLY has Mag Oxide... rel. poor absorption (hence more left in gut
to cause diarrhea... forget it.  Follow Steve Fowkes advice and just get glycinate or glyconate.
he recommended 500mg bid.

MAG Oxide:
The ligand of choice for <b>large-scale manufacturers of multivitamins and minerals </b>containing magnesium is the <a title="Magnesium oxide" href="/wiki/Magnesium_oxide">magnesium oxide</a> due to its compactness, high magnesium content by weight, low cost, and ease-of-use in manufacturing. However it is <b>insoluble in water.</b> Insoluble magnesium salts such as magnesium oxide or magnesium hydroxide (<a class="mw-redirect" title="Milk of magnesia" href="/wiki/Milk_of_magnesia">milk of magnesia</a>) depend on <b>stomach acid for neutralization before they can be absorbed, and thus are relatively poor oral magnesium sources, on average</b>.
 
Magnesium is absorbed orally at about 30% bioavailability from any <i>water soluble salt,</i> 
such as <a title="Magnesium chloride" href="/wiki/Magnesium_chloride">magnesium chloride</a> or <a title="Magnesium citrate" href="/wiki/Magnesium_citrate">magnesium citrate</a>. The citrate is the least expensive soluble (high bioavailability) oral magnesium salt available in supplements, with 100 mg and 200 mg magnesium typically contained per capsule or tablet.
 
<a title="Magnesium aspartate" href="/wiki/Magnesium_aspartate">Magnesium aspartate</a>, <a title="Magnesium chloride" href="/wiki/Magnesium_chloride">chloride</a>, <a title="Magnesium lactate" href="/wiki/Magnesium_lactate">lactate</a>, <a title="Magnesium citrate" href="/wiki/Magnesium_citrate">citrate</a> and <a title="Glycine" href="/wiki/Glycine">glycinate</a> each have bioavailability 4 times greater 
than the oxide form and are equivalent to each other per amount of magnesium, though not in price</p>
