I have been writing on these boards so long I could have written a book. Almost 3 years ago I wrote a post on the old board about magnesium so I won't repeat it just click on this and read it and I'll add to it--- http://www.healthboards.com/irritabl...rome/3453.html
If you take too much it will make your bowels loose!!!
Magnesium is needed for the absorption of calcium and potassium but it's relationship is very intimit but not well understood.
To best absorb calcium --you need 2 parts calcium to 1 part magnesium also vitamin D. The magnesium that you have in your body is the fourth most plentiful cation(ion). About 50 % is in the bones. The amount of Mg that is in the blood and the amount in the cells or total body is not closely related but low blood magnesium is an indicator of total magnesium in the body.
The homeopathic remedy -- Magnesia Phosphorica is absorbed in the mouth and bypassing the digestive system that can be a little messed up and magnesium absorption in materal doses does depend on stomach pH(acid levels). It works on an entirely different level as the mineral magnesium than homeopathic remedy.
The Homeopathic type is very diluted and is extremely good for anti-spasms, cramping muscles with radiating pain. Neuralgic pain that is relieved by wamth. The symptoms that it can help are about 10 pages long from sleeplessness because of indigestion to menstrual pain to Angina Pectocis, spasmotic cough, bloating gas pains, cramping in calves, writers cramps and on and on.
It is good for so many spasms type pains ---I carry a bottle around while out of the house.
I hope this is not too much info for such a simple question!!!
