When you're not going much when you go and then have a few hours after that to be sure. Its a little risky even then.
I am not a healthcare professional; however, I have personally taken magnesium citrate multiple times. I like it because it isn't something that will make me run through everyone to get to the restroom or make me tell someone mid lecture, "Excuse me, I have to go, RIGHT NOW." The cool thing about magnesium citrate is it will let the body know when its working, but give you enough time to respond.
Took magnesium citrate 5 days ago. It worked some but did not clean me out completely. what now?
