Selenium (Se)⁷

Also known as: The mineral, Selenium, is represented on the periodic table as Se.

Elemental selenium is relatively nontoxic and is considered to be an essential trace element.

However, hydrogen selenide (H2Se) and other selenium compounds are extremely toxic, and resemble arsenic in their physiological reactions.

Cattle grazing in selenium-rich soil have shown toxicity caused by increased levels of selenium. The cattle developed muscle, visual, and heart problems.

Benefits and Uses of Selenium:

Selenium deficiency may occur in premature infants who naturally tend to have about one-third the selenium levels of full-term infants. It is not known if these lower levels result in adverse consequences.

Selenium deficiency occurs in regions of the world containing low-selenium soils, including parts of China, New Zealand, and Finland.

In Keshan Province in China, a condition called Keshan disease occurs which results in the deterioration of regions of the heart and the development of fibers in these areas.

This disease, which may be fatal, is thought to result from a combination of selenium deficiency and a virus and has claimed the lives of many children in China until the relationship to selenium was discovered and selenium supplements were provided.

Selenium is an essential trace element. It is an integral part of enzymes, which are critical for control of the numerous chemical reactions involved in brain and body functions.

Selenium has a variety of functions, the main one being its role as an antioxidant in the enzyme selenium-glutathione-peroxidase.

This enzyme neutralizes hydrogen peroxide, which is produced by some cell processes and would otherwise damage cell membranes.

Selenium also seems to stimulate antibody formation in response to vaccines. It may also provide protection from the toxic effects of heavy metals and other substances.

Selenium may assist in the synthesis of protein, in growth and development, and in fertility, especially in men. It has been shown to improve the production of sperm and sperm motility.

Selenium deficiency may occur in patients fed intravenously for long periods of time.

Selenium can be incorporated into the diet or taken as a supplement.

Side Effects of Selenium:

The amount of selenium that would cause toxicity in humans is not known. Excess selenium intake can cause problems with the strength of teeth and the tooth enamel.

Other problems may include loss of teeth, hair, and nails. Skin inflammation, nausea, and fatigue can also occur.
