Mgo (magnesium oxide or magnesia) is a mineral that is used as a supplement to provide dietary magnesium; it is also used to relieve indigestion or constipation.
Magnesium is used throughout the body as a critical chemical in a wide spectrum of chemical processes. Magnesium is used to help the body produce energy, maintain the beating of the heart, regulate glucose levels, activate nerves and muscles, and build bone. Magnesium is widely available in food, so magnesium deficiencies are typically the result of poor nutrition. Because magnesium is so vital to the body's functions, chronic magnesium deficiency can be life-threatening.
To relieve indigestion, Mgo neutralizes the acid in the stomach that causes indigestion. Mgo is also an osmotic laxative—it draws water into the intestines from the intestinal tissues to soften stools and make them easier to pass.
The most common side effects of Mgo are diarrhea, nausea, vomiting, slow heartbeats, or rectal bleeding. Allergic reactions are rare. However, Mgo supplements or remedies often have other inactive ingredients, which may cause allergic reactions. These side effects include itching, rash, hives, eye pain, trouble breathing, or headache. If you have any reaction to Mgo supplements, stop taking the supplement and consult with your physician.
