Selenium

Selenium is a trace element essential in small amounts, but can be toxic at high levels. Humans and animals require selenium for the function of a number of selenium-dependent enzymes, also known as selenoproteins.

During selenoprotein synthesis, selenocysteine is incorporated into a very specific location in the amino acid sequence in order to form a functional protein.

Selenium supplements are available in several forms. Sodium selenite and sodium selenate are inorganic forms of selenium.

Selenate is almost completely absorbed, but a significant amount is excreted in the urine before it can be incorporated into proteins.

Selenite is only about 50% absorbed but is better retained than selenate once it is absorbed.

Selenomethionine, an organic form of selenium that occurs naturally in foods, is about 90% absorbed. Selenomethionine and selenium-enriched yeast, which mainly supply selenomethionine, are also available as supplements.

The average American diet is estimated to provide about 100 mcg/day of selenium, above the current RDA (55 mcg/day) and appears sufficient to maximize plasma and cellular glutathione peroxidase activity. Eating a varied diet and taking a daily multivitamin supplement should provide sufficient selenium for most people.
