Pharmacology
Magnesium is one of the most common minerals on earth, and many foods contain it. Magnesium oxide is a mineral supplement used to treat or prevent low levels of magnesium in the blood. The body needs magnesium for good health, and it takes part in over 600 cellular reactions. In fact, every cell and organ needs this mineral to work properly. It contributes to bone health, as well as proper brain, heart and muscle function. Magnesium prevents or controls convulsions by blocking neuromuscular transmission and decreasing the amount of acetylcholine liberated at the end plate by the motor nerve impulse. It is said to have a depressant effect on the central nervous system (CNS), but it does not adversely affect the woman, fetus or neonate when used as directed in eclampsia or pre-eclampsia. Approximately 24 to 76% of ingested magnesium is absorbed in the gastrointestinal tract, mainly by passive paracellular absorption in the small intestine. About 20% of the magnesium in human serum is protein bound. Of this fraction, approximately 60 to 70% is bound to albumin and the rest is bound to globulin proteins. Magnesium can bind to 3751 human proteins. It does not appear to be metabolized, and most of it is excreted by the kidneys.
