Drug Overview

Magnesium citrate is a saline laxative that comes in an oral solution form, designed to help relieve occasional constipation (irregularity). It works by drawing water into the intestines, which helps to stimulate bowel movements, typically producing results within 30 minutes to 6 hours after taking it.

This product is dye-free and sugar-free, and it has a pleasant cherry flavor, making it easier to consume. If you're experiencing occasional constipation, magnesium citrate may be a helpful option to consider for promoting regularity.
