Magnesium citrate is a kind of chemical substance that has different medicinal uses. It is often taken as a syrup as a laxative, and in this sense can also be used to clear out the bowels prior to having a colonoscopy or surgery. In the pill supplement form, it can also be used to attempt to keep away kidney stones.

In one of its main usages, as a laxative, magnesium citrate works through a process that is called osmosis. In this, diffusion of water takes place through a semi-permeable membrane. In this case, it is the tissues along the intestine, through which the chemical attracts the water. Once sufficient amounts of water have come into the intestine, this leads to easier bowel movements.

The function of this medicine is best accomplished when the individual has an empty stomach. After the magnesium citrate has been taken by the person, then it should be followed up by an 8 ounce cup of water or juice. This liquid helps the chemical to be absorbed, and is useful in avoiding potential complications.

Dosage may vary in some circumstances, and also depending upon the concentration of magnesium citrate in the syrup. Common doses are between 7 and 10 fluid ounces for adults and children who are at least 12 years old. This is at a concentration level of 1.745 grams per each fluid ounce. Please also keep in mind that this medication should not be taken under some circumstances, and look for qualified medical advice.
