Constipation is a widespread issue, and most people experience it at some point in their lives. Many people use magnesium products, including magnesium citrate, to treat this uncomfortable condition.

Before taking magnesium citrate, it is essential that a person understands how it works, its side effects, and how it interacts with other substances.

There are times when magnesium citrate may not be the best option for treating constipation, and choosing other alternatives may help avoid any complications.

Causes of constipation

Constipation is when a person has fewer than three bowel movements a week. Stools are usually hard, dry, or lumpy, and may be difficult or painful to pass.

In many cases, addressing the underlying cause for constipation may reduce the need for medications, including magnesium citrate. These include a low fiber diet, immobility, dehydration, or medical conditions.

How does magnesium citrate work for constipation?
Compounds such as magnesium citrate work by pulling water into the intestines. This water combines with the dry stool, making it easier to pass. Medications that work in this way are called osmotic laxatives.

When used correctly, many people find that magnesium citrate is a simple solution to occasional constipation.
