Let’s talk about Magnesium Oxide. It's a form of magnesium that’s commonly used, but not always well understood. Magnesium Oxide is not the most easily absorbed, but it does have its place, especially if you're looking for help with occasional constipation or digestive sluggishness. Because it pulls water into the intestines, I often recommend it short-term for bowel regularity, not necessarily for boosting your magnesium levels. If absorption is your goal, you might want to look at other forms.
