How long does magnesium citrate take to work?

To feel the effects of a typical dose of magnesium citrate, it can take anywhere from half an hour to three hours. It will enter your bloodstream gradually, speed up the movement of your bowels, and raise the fluid level in your intestines. Then you won’t have any difficulty passing stools.

You should heed the recommendations of a qualified medical practitioner, whether they come from your primary care physician or the pharmacist.

What Is Magnesium Citrate?

Magnesium citrate causes the intestinal tract to absorb more water via osmosis. It improves bowel motions and is used to treat irregular bowel movements. In addition, if you need to have your intestines cleaned out before medical treatment, you can use it as a laxative. 

It is also accessible in a liquid version, in addition to tablets. To relieve constipation that isn’t long-lasting or persistent, one can take this laxative. It’s not a permanent fix, but it’s ideal if you need something quickly.
