magnesium citrate how long does it take to work

Magnesium citrate typically takes between 30 minutes to 6 hours to start working. The time for it to take effect can vary based on factors such as dosage, whether it is taken on an empty stomach, hydration levels, individual digestive health, and the form of magnesium citrate consumed (liquid tends to work faster). After ingestion, magnesium citrate works by drawing water into the intestines, softening the stool, and stimulating bowel movements. Most people will experience the laxative effects within that time frame, and the effects usually start to wear off after about 4 hours, with normal bowel habits resuming within a day.
