The Presence and Function of Magnesium in the Body

Magnesium is an important mineral needed by the human body, as it is involved in almost every physical process in the body. The adult human skeleton houses 50-60% of the magnesium in the human body. The remaining magnesium occurs in the muscles and other soft tissue. As an essential mineral, magnesium functions as a catalyst to aid the many biochemical processes in the body. For example, magnesium is important for proper muscle function, energy production, calcium absorption, and hormone support, among many others.

Magnesium Deficiency Implications

With so many bodily functions dependent on magnesium, a lower level can have specific implications. Some estimations are that roughly half of the U.S. population may be deficient in magnesium. A prolonged or severe lack of magnesium has been understood to impede vitamin D’s role in the body, as well as potential hampering of the availability of calcium to the body’s systems. Therefore, magnesium deficiencies may be associated with certain chronic challenges such as cardiovascular issues, and bone loss. There is also a potential connection to the risk of some conditions related to type 2 diabetes.

Magnesium Oxide Potency

Magnesium oxide, containing more magnesium than other magnesium compounds, is made by calcinating magnesium with pure oxygen. Magnesium oxide has a neutral taste, and is available in many forms, from granular to powder. Magnesium oxide contains the highest percentage of magnesium compared to other compounds. This allows more elemental magnesium to be contained in a smaller dosage.

What Does Magnesium Oxide Do?

A supplement of magnesium oxide may be used to benefit people with a magnesium deficiency. Supplementing with magnesium oxide is currently used to support such conditions as heartburn, digestive issues, and even migraines. Some recent study data shows that patients who suffer from migraines may also be magnesium deficient.

Magnesium oxide has also been found to help support minimizing the symptoms of depression and stress. It has been understood to potentially lower blood pressure and reduce the risk of strokes. It is also being studied for use in the support of other chronic conditions, such as respiratory and cardiovascular issues, blood pressure and pain management.

How is Magnesium Oxide Used?

Magnesium oxide is used mostly as a component in nutritional supplements. STAUBER supplies bulk Magnesium Oxide in both powder and granular form to manufacturers, mainly for use in dietary supplements for mineral fortification.  For the consumer, magnesium oxide comes in capsules or chewable forms. It is available as an over-the-counter supplement. There are possible side effects or contraindications for magnesium oxide use, so physicians or pharmacists should be consulted before using. Although most users do not experience serious side effects, it is recommended that any side effects should immediately be reported to a doctor.

STAUBER is a Leading Supplier of Magnesium Oxide

STAUBER has been supplying Magnesium Oxide for supplements since the foundation of the company over 40 years ago and is one of the largest distributors of Magnesium Oxide in the US.  We offer a wide range of magnesium oxide products in various densities.  The wide array of bulk Magnesium Oxides are available at various levels of moisture content, bulk density, Magnesium Oxide content and loss on ignition.


Magnesium is one of the most plentiful and vital minerals on the earth and in the sea. The body’s need for it is expressed in hundreds of ways.  Considering that a high level of the population may be magnesium deficient, and magnesium from food is typically absorbed at only 30%, supplementation can be very important, and sometimes even critical.

Magnesium oxide contains the highest percentage of magnesium per milligram compared to other magnesium compounds. Its use is varied and can be applied in human and veterinary nutrition. Supplementation in the human diet is being researched more extensively every day. The use of magnesium oxide in new nutraceuticals to support overall human well-being, from bone to cardio to cognitive, is growing significantly.
