Magnesium citrate is a saline laxative used for bowel evacuation before diagnostic procedures or surgery of the colon.
What Is Magnesium Citrate?
Magnesium citrate is used to remove bowel from the intestines. It is primarily used before medical procedures such as a colonoscopy but can be taken to relieve constipation in the case that more mild laxatives have failed. Unless indicated by a physician, this product should not be used regularly to relieve constipation as overuse may cause laxative dependence, which means the loss of bowel function or inability to produce a bowel movement without the assistance of the product.
How Does Magnesium Citrate Work?
Magnesium citrate is a hyperosmotic saline laxative that works by pulling the water from the body’s tissues into the small intestines. The additional water in the intestines assists in moving the bowels. It generally will produce results in one-half to three hours following consumption.
