This is one of my favorites!!!! I like to use this for discomfort (pain); constipation; and over all balance of minerals.  In general terms, magnesium supplements are well tolerated and absorbed.  There are some drugs that do interfere with magnesium absorption, they are diuretics, insulin and digitalis.  People with kidney disease or severe heart disease SHOULD NOT TAKE MAGNESIUM SUPPLEMENTS UNLESS UNDER THE SUPERVISION OF A PHYSICIAN.

Deficiency symptoms: Muscle cramps; menstrual cramps; PMS; sugar cravings; fatigue; nervousness; anemia; anxiety; facial tics; hypoglycemia; hyperactivity (especially in children); high blood pressure; poor circulation & kidney stones.  If you have any of these symptoms, please discuss them with your doctors.
