A member asked:
Magnesium oxide 400mg take 1 to 2 tabs daily prn for muscle spasm n legs. will it cause diarrhea, if used this way? my magnesium is borderline low
A doctor has provided 1 answer
Maybe: That is one of its effects, so if take too many doses too close together, magnesium can cause diarrhea. 400-800mg a night not highly likely to do this, and may help raise your level over time.
