What is magnesium oxide

Magnesium oxide is a chemical compound composed of magnesium (Mg) and oxygen (O) atoms. It is commonly used both as a magnesium supplement and as an ingredient in various industrial applications. Magnesium oxide is formed when magnesium metal reacts with oxygen or air.

What is magnesium oxide

Here are some key points about magnesium oxide:

  • Supplement Uses: Magnesium oxide is often used as a dietary supplement to provide magnesium to the body. It has a relatively high percentage of elemental magnesium by weight, which makes it a popular choice for magnesium supplementation. However, its bioavailability, or the extent to which magnesium is absorbed and used by the body, may be lower than that of other forms of magnesium supplement, such as magnesium glycinate or magnesium citrate.

  • Laxative effect: Magnesium oxide can have a laxative effect when taken in large amounts. This is due to its ability to draw water into the intestines, promoting bowel movements. Because of this, magnesium oxide is sometimes used as an over-the-counter remedy for constipation.

  • Antacid use: Magnesium oxide is also used as an antacid to relieve symptoms of heartburn, acid indigestion and upset stomach. When magnesium oxide reacts with stomach acid, it forms magnesium chloride, which can help neutralize excess stomach acid.

  • Industrial Applications: Magnesium oxide has various industrial uses. It is commonly used in the production of refractory materials (materials that can withstand high temperatures and harsh conditions), as an ingredient in building materials, and in the manufacture of ceramics and glass.

  • Health Considerations: Like any dietary supplement, it is important to use magnesium oxide responsibly and within recommended dosages. Taking magnesium oxide in excessive amounts can cause gastrointestinal problems, including diarrhea and stomach upset. It is advisable to consult a healthcare professional before starting magnesium oxide supplementation, especially if you have underlying health conditions or are taking medications.

  • Forms: Magnesium oxide is available in a variety of forms, including tablets, capsules, and powders. The rate of dissolution and absorption may vary from formulation to formulation.

While magnesium oxide can be an effective way to supplement magnesium intake, some individuals may prefer other forms of magnesium supplements that provide better absorption and reduce the risk of gastrointestinal discomfort. As always, it is recommended to consult with a healthcare provider before starting any new supplement regimen to ensure that it is appropriate for your specific health needs and circumstances.
