An essential mineral that is a component of an antioxidant enzyme, glutathione reductase, that is key in tissue respiration. Food sources of selenium include seafoods; some meats, such as kidney and liver; and some grains and seeds. Too much selenium may cause reversible balding and changes in the nails, give a garlic odor to the breath, and cause [..]

An element found in trace amounts in soil; closely related to sulfur

element name, Modern Latin, from Greek selene "moon" (see Selene). Named by Berzelius (1818), on analogy of tellurium, with which it had been at first confused, and which was named for the e [..]

A nonmetallic element obtained chiefly as a by-product in copper refining. WCOL9.

An essential dietary mineral.

Selenium is an essential trace mineral. Selenium activates an antioxidant enzyme called glutathione peroxidase, which may help protect the body from cancer. Yeast-derived forms of selenium have induce [..]

Selenium, a lustrous-gray metal, is named after Selene, the Greek goddess of the moon. It was first discovered in 1817 by J.S. Berzelius in Fahlun, Sweden, as part of the red residue found in sulfuric acid prepared at a pyrite mining operation. Selenium is primarily recovered from anode slimes in the electrolytic refining of copper and is used in g [..]

(n) a toxic nonmetallic element related to sulfur and tellurium; occurs in several allotropic forms; a stable grey metallike allotrope conducts electricity better in the light than in the dark and is [..]

A vital antioxidant combined with Vitamin E. Protects the immune system. Healthy heart & muscles.

A mineral used for diseases of the heart and blood vessels, including stroke and atherosclerosis (the “hardening of the arteries”). It is also used for preventing several types of cancer, including cancer of the prostate, stomach, lung, and skin.

a non-metallic element in the same chemical group as sulfur; its compounds are harmful to wildlife or people when found above certain levels in water

Selenium is a trace mineral incorporated into proteins, to form selenoproteins. Selenoproteins are antioxident enzymes that help prevent cellular damage from free radicals (free radicals are natural p [..]

Symbol:"Se" Atomic Number:"34" Atomic Mass: 78.96amu. It is classified as a non-metal. Selenium is found in many forms. It may have red crystals or a grayish metal [..]

This metal is a nutritionally essential trace element that is toxic at higher doses.  High levels of selenium have been shown to cause reproductive failure and birth defects in birds.

The MCL is 0.05 mg/L. Selenium is associated with hair or fingernail loss, numbness of fingers and toes, and circulatory problems. For freshwater the concentration should be less than 1.5 mg/L.  

An element with the atomic symbol Se, atomic number 34, and atomic weight 78.96. It is an essential Micronutrient for Mammals and other Animals but is toxic in large amounts. Selenium protects intrace [..]

Selenium is an essential mineral that is needed in small amounts. Selenium plays a vital role in reducing cellular damage and supports the immune response.

Selenium (see minerals) is required for the activation of thyroid hormone from its precursors. It also supports the immune system and is involved with vitamin E as an antioxidant (see vitamin E, antio [..]

Selenium is an essential mineral that is needed in small amounts. Selenium plays a vital role in reducing cellular damage and supports the immune response.

An essential trace mineral with antioxidant properties.

A mineral that is needed by the body to stay healthy. It is being studied in the prevention and treatment of some types of cancer. Selenium is a type of antioxidant.

A chemical element with the symbol Se and atomic number 34.

Selenium contributes to the expansion of the immune system and is therefore, essential to the equine body. Also it collaborates with Vitamin E.

[Se] A chemical element with light-sensitive properties that makes it useful as a semiconductor material in metallic rectifiers and photocells.
