Magnesium Oxide: Frequently Asked Questions Answered

Magnesium oxide is a magnesium-containing compound coupled with oxide ions. It is chemically basic and has a pH level of 8–10. But these basic properties are not very strong, as its oxide ions are weakly bound. It reacts with water to form magnesium hydroxide which is also a base.

Both magnesium oxide and magnesium hydroxide are stable at high temperatures and are typically mostly insoluble in water. Magnesium oxide (MgO) reacts with water (H2O) under certain conditions to form the alkaline magnesium hydroxide (Mg(OH)2). MgO + H2O → Mg(OH)2 This reaction can be reversed by heating the solution.

You can take magnesium oxide daily for nutritional purposes, but most tablet or capsule brands recommend only 250 mg per day. You can obtain the rest of the magnesium your body requires from your diet. You should take the medicine with approximately one glass (~250ml) of water with a meal.

Magnesium oxide may help in improving how well you sleep, as it plays a significant role in strengthening the nervous system. It activates system mechanisms that can calm you and improves sleep quality. It can also help to reduce depression and anxiety, which are two of the main factors behind disturbed sleep.

High dosages of magnesium oxide may cause dangerously high levels of magnesium in your blood. Some people may experience side effects such as bloating and diarrhea. These, in turn, reduce the effectiveness of other medications. Take precautions to keep this medication out of children’s reach to avoid unwanted consumption.

A 2003 study found that the body absorbs magnesium citrate more effectively than magnesium oxide. Doctors also prescribe a dosage of magnesium citrate for treating constipation. On the other hand, some may face undesirable digestive side effects, like diarrhea, with magnesium citrate. Your doctor will consider your medical history and symptoms before prescribing either magnesium oxide or citrate.

Magnesium oxide is generally safe when you take the appropriate dosage. However, excessive magnesium oxide over long periods can result in high magnesium levels in the blood, or hypermagnesemia, an electrolyte disorder. The complications of hypermagnesemia, like lowered breathing rate and decreased reflexes, can prove to be fatal thus adequate precautions must be taken while administering the drug.

Don’t take magnesium oxide as an antacid for over 2 weeks unless your doctor prescribes it to you. Don’t use it as a laxative for over a week, unless you’re specifically prescribed an appropriate dosage for a longer duration. Take suitable precautions as this supplement can have side effects like diarrhea, stomach upsets, bloating, and gas.

Magnesium regulates neurotransmitters that signal the nervous system and brain. Some studies have found that magnesium oxide can work as a natural treatment for anxiety and depression in select populations. A 2017 review found that magnesium oxide, when supplemented with vitamin B6, reduced anxiety and stress in women with premenstrual syndrome.
