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 is 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 also may 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.

Food Sources
Fish, shellfish,
red meat, grains, broccolis, onions, tomatoes, tunas, eggs, chicken, liver,
and garlic are all good sources of selenium. The amount of selenium in vegetables
is dependent on the selenium content of the soil. Brewer's yeast and wheat
germ, both considered "health foods," are also good sources of selenium.

Side Effects
Selenium deficiency
may occur in patients fed intravenously for long periods of time.
Keshan disease
is caused by a deficiency of selenium. This leads to an abnormality of the
heart muscle, and it claimed the lives of many children in China until the
relationship to selenium was discovered and selenium supplements were provided.
Cattle grazing
in selenium-rich soil have shown toxicity caused by increased levels of selenium.
The cattle developed muscle, visual, and heart problems.
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.

Recommendations
Selenium is often
available in multivitamin and mineral supplements. The suggested intake by
nutrition experts is 50 to 200 micrograms for adults, which the average diet
in the U.S. usually provides. Specific recommendations for each nutrient
depend on age, gender, and other factors (such as pregnancy).
Evidence exists
that selenium may play a role in cancer prevention, but better studies are
needed. There have been mixed results regarding selenium's impact on cardiovascular
disease.
