What is magnesium citrate used for?
Magnesium citrate is a form of magnesium that is often used in two common ways: as a magnesium supplement and as a laxative. Because it draws water into the intestines, it can help relieve constipation. It’s also sometimes used to help clear the bowel before certain medical procedures. [1]
How does magnesium citrate work for constipation?
Magnesium citrate is an osmotic laxative. It works by increasing water in the bowel, which softens stool and can stimulate bowel movements. This is why it’s commonly used to treat constipation. [1]
Is magnesium citrate used for magnesium deficiency?
Yes. Since it provides magnesium, it can be used as a magnesium supplement when someone needs additional magnesium. Magnesium plays roles in muscle and nerve function. [1]
Why do some people take it before colonoscopy or bowel prep?
Some bowel-prep regimens use magnesium citrate to help empty the intestines before procedures like colonoscopy, because it can produce diarrhea and bowel clearance. The specific product and instructions depend on the prep protocol your clinician prescribes. [1]
What should people watch out for?
Magnesium citrate can be risky if used incorrectly or in people with certain health conditions, especially reduced kidney function, because magnesium can build up in the body. People should follow label or clinician directions closely and ask a pharmacist or doctor if they have kidney disease or take medications that affect magnesium or the bowels. [1]
What’s the difference between magnesium citrate and other magnesium forms?
Magnesium citrate is typically chosen when the goal includes either supplementation or laxative effects, since citrate is more likely to have an effect on stooling. Other forms (like magnesium oxide or glycinate) are often used primarily for supplementation, but they differ in how well they dissolve and how they affect the gut. [1]
