Magnesium Citrate and Oxide Benefits Dosage and Side

 · Magnesium citrate and magnesium oxide generally have few side effects. However some people may experience diarrhea and stomach discomfort. If it s continually used as a laxative you may develop laxative dependence. This is when the bowel loses its ability to effectively clear stools without the help of a laxative.
