Selenium Plus, provided by Douglas Laboratories, supply 200 mcg of Selenium, 100 mg of Vitamin C, and 60
IU natural vitamin E in each capsule.
Vitamin E is one of the body’s most important antioxidant nutrients. Antioxidants protect healthy cells from
oxidative and free radical damage. Free radicals are unstable chemicals formed in the body during metabolism
and from exposure to environmental sources, such as pollution and cigarette smoke. Free radicals are
necessary for energy metabolism and immune function, but when an excessive number of free radicals are
formed, they can attack healthy cells, especially cell membrane lipids and proteins. This, in turn, is thought to
contribute to a number of degenerative diseases.
Vitamin E is an especially valuable antioxidant in the cell membranes, where it prevents oxidation of
unsaturated fatty acids by trapping free radicals. This helps stabilize and protect cell membranes, especially
red blood cells and tissues sensitive to oxidation, such as the lungs, eyes, and arteries.
Selenium is a nutritionally essential trace element for humans and animals. The National Research Council’s
Recommended Dietary Allowance for selenium in adults ranges from 55 to 75 mcg per day depending on age
Selenium is a cofactor to about 10 selenoproteins in the body; the most important of these appears to be
glutathione peroxidase (GPX). GPX uses glutathione to reduce hydrogen peroxide and thus protect cells and
plasma against free radical injury. GPX activity depends on an adequate supply of dietary selenium. Recently,
selenium as selenocysteine has been identified in the active center of type 1 and 3 iodothyronine deiodinases,
two important enzymes regulating the formation and degradation of the active thyroid hormone,
triiodothyronine (T3). Another important selenoprotein appears to be selenoprotein P, but its functions remain
unclear. Selenium and vitamin E appear to have synergistic effects, since some signs of vitamin E deficiency in
animals can be alleviated by dietary selenium.
Vitamin C (ascorbic acid) has numerous biological functions. Foremost, it is essential for the synthesis of
collagen and glycosaminoglycans which are the building materials of all connective tissues, such as skin,
blood vessels, tendons, joint cartilage and bone. Vitamin C participates in the biosynthesis of carnitine,
serotonin, and certain neurotransmitters, including norepinephrine. Vitamin C is among the most powerful
antioxidants in humans and animals. It is a water-soluble, chain-breaking antioxidant that reacts directly with
superoxide, hydroxyl radicals, and singlet oxygen. The antioxidant functions of vitamin C appear to
have clinical significance in providing protection from free radical damage to the eyes, lungs, blood and the
Selenium Plus may be a useful dietary supplement for individuals wishing to increase their intake of selenium,
vitamin C and vitamin E.
