The Power of Magnesium: Benefits, Side Effects, and Deficiency Warning Signs.

Magnesium oxide is a supplement that contains high traces of elemental magnesium and is available in tablet or capsule form. It is a popular form of magnesium due to its low cost and widespread availability. It is often used to relieve constipation, heartburn, indigestion, and migraine headaches. However, it may cause gastrointestinal upset and diarrhea in some individuals. It is important to consult with a doctor before taking magnesium oxide, especially if you have kidney, heart, liver, or intestinal disease, or are on medications that may interact with it.
