Milk Of Magnesia Vs. Magnesium Oil

Magnesium is the fourth most abundant mineral in your body. It plays an important role in contraction of muscles, production and transportation of proteins and energy, and in the proper functioning of enzymes. You should consume 80 to 420 milligrams of magnesium per day, depending on your age and overall health, according to the National Institutes of Health. Foods that contain magnesium include nuts, spinach, whole grains and dairy products, and you can get it from dietary supplements. Milk of magnesia, usually taken for digestive problems, and magnesium oil are two different forms of magnesium supplements.

Chemistry

Milk of magnesia is actually magnesium hydroxide. Magnesium oil, on the other hand, is a concentrated solution of magnesium chloride, which happens to have an oily texture caused by its ability to attract water molecules.

Available Forms

Milk of magnesia comes in tablet, capsule and syrup form to be taken orally. The dosage varies depending on your health history and the reason you're taking it. Oil of magnesium is generally sprayed on the skin for the most beneficial results. The oil can be applied to specific areas or to the entire body. You can leave it on or wipe it with a wet washcloth after 30 minutes. Adding the oil to a warm bath may also be beneficial.

Uses

Milk of magnesia is a powerful laxative that is often used to relieve constipation. It reduces the acid in the stomach and increases water content in the intestines, which helps promote defecation. Oil of magnesia is taken to relieve acidity, heartburn and sour stomach. However, Dr. Marc Sircus, director of the International Medical Veritas Association and author of the book “Transdermal Magnesium Therapy,” suggests that magnesium is poorly absorbed orally and application of magnesium oil to the skin is the best way to overcome deficiency of the mineral. Magnesium oil massage can help prevent injuries and increase athletic performance, says the IMVA. It also helps improve flexibility and reduce stress.

Side Effects

Upset stomach, cramps, vomiting and diarrhea are the common side effects associated with milk of magnesia. It may also lead to serious allergic reactions characterized by swelling of face, shortness of breath and hives. Seek emergency medical help if you experience these symptoms after taking milk of magnesia. The magnesium chloride in magnesium oil can lead to similar allergic reactions, and these should be addressed immediately. In large doses, it can also increase levels of magnesium in the body, which can cause low blood pressure, diarrhea and muscle weakness.
