I do not agree with the previous poster.
Most magnesium is stored in the bones. The type of magesium that is absorbed without the digestion doing much to it is the chelated type that is attached to a protein amino acid like glycine or lycine.

The process is patented by Albion Labs in Utah and is produced by several companies in the US. --- Doctors Best, Solgar, Kal, Carlson and other vitamin companies.

It has been found that magnesium is absorbed better if taken spead out like 3 times daily. If it is taken in a single dose the absorption is less than 14% but the absorption goes to almost 40% when taken 3 times daily.

We in the US get alot of calcium in foods and dairy products but it is estimated that 70% are deficient in magnesium.

You really need magnesium along with vitamin D to absorb calcium best. The relation should be 2 parts calcium to 1 part magnesium.

Other forms of magnesium are aborbed pretty well but the organic type is the best. Aspartates, oratates, citrates, oxides are all good.

If you think you lack magnesium at the cell level --the most sensitive test is called an intracellular (mononuclear cell) magnesium screen. It is more sensitive than the normal blood serum test that is usually performed.

I wish you well---Harry
