The Antioxidant Minerals

Because the antioxidant vitamins tend to get most of the press and publicity, many people are unaware that there are also important antioxidant minerals that are essential to the body’s continuous battle against free radicals and the damage they do. Making sure that the proper nutrients are consumed daily is a necessary part of helping the body to be able to keep free radical damage as low as possible.

A mineral, vitamin or other nutrient is deemed antioxidant if it, on its own or as an essential part of a group of substances, it serves to bring free radicals under control. Free radicals are unstable molecules that generally come from both environmental contaminants and some of the body’s natural processes. There are certain minerals that are an integral part of managing the free radical population within the body.

Selenium has come to be recognized as one of the most important of these minerals, though each does play an important role in free radical management. Selenium is an essential component of the antioxidant enzyme glutathione peroxidase, and this substance is one that is able to stabilize the free radical.

Since the universal acceptance of the mineral selenium, a trace element, as an essential nutrient during the 1950’s, researchers have been studying the ways that it affects health. In 1973, researchers confirmed the antioxidant properties of the mineral selenium, and since then, numerous studies have demonstrated that it may play a significant role in the prevention of certain types of cancers.

However, it should be noted that excessively high levels of selenium can cause serious health problems – as can deficiencies of selenium – and some studies have found excessively high levels of selenium to be associated with other types of cancer. The body is a delicate balance of a variety of chemicals and substances, and optimum performance requires thought and planning.

The minerals zinc and copper form part of another of the body’s important antioxidant enzymes. This enzyme, called superoxide dismutase, is present in the body in two forms. The first form is found almost everywhere in the body, and it needs zinc and copper to function.

The second form of this important antioxidant enzyme, superoxide dismutase is found specifically in the mitochondria, which is the part of the cell responsible for changing the energy that comes from the various nutrients into a form that can be used by the cells. In this second form of the enzyme superoxide dismutase, it is the mineral zinc and the mineral manganese that are essential to the antioxidant enzyme’s ability to function properly.

Making sure that the body has all of the minerals, vitamins and other nutrients it needs each day is very important for both day-to-day and long-term health and well-being. Dietary supplements are a safe and effective means of seeing that the body does have all of the nutrients it needs for all of its systems to work at peak performance levels, especially those that maintain daily health and those that protect health over the long-term. However, nutritional supplements are powerful agents, and must be used within the established dosage guidelines to be beneficial to the health. Used in this fashion, dietary supplements can serve as a valuable part of any health routine.
