Elevated Selenium intake may be associated with reduced cancer risk.
Helps protect against cancer, heart disease and stroke, raises sperm counts in men, keeps dandruff in control.
Selenium is an essential trace element which functions as cofactor for reduction of antioxidant enzymes such as glutathione peroxidases and thioredoxin reductase, and plays a role in cellular apoptosis.
A mineral that when combined with Vitamin E acts as an antioxidant, works in metabolic processes, and aids in normal body growth and fertility. Selenium deficiency may be a factor in cancer of the prostate because the mineral is needed in sufficient concentration in the body for life and health. Selenium protects cell membranes and prevents free radical generation thereby decreasing the risk of cancer and disease of the heart and blood vessels. Selenium preserves tissue elasticity; slows down the aging and hardening of tissues through oxidation.
Selenium's major function is as an antioxidant.
Prevents some forms of cancer especially male cancers.
Protects against toxic effects of other metals such as lead and cadmium.
Certain researchers have found vitamin E, zinc and selenium synergistically provide relief from enlarged prostate. Individual suffering from alcohol problems related to liver cirrhosis can potentially find relief with selenium. Selenium is known to be an important antioxidant and is enhanced in it's potency when combined with vitamin E. As an antioxidant, it protects the immune system by preventing the formation of free radicals, which are known to damage cells in other body components. Selenium 's principal function is to inhibit the oxidation all of lipids (fats). Research indicates selenium can be a preventative against the formation of certain types of tumors. Selenium and vitamin E synergistically act to produce antibodies which help maintain a healthy heart and liver.
The essential trace mineral, it, is of fundamental importance to human health. As a constituent of selenoproteins, it has structural and enzymic roles, in the latter context being best-known as an antioxidant and catalyst for the production of active thyroid hormone. Selenium is needed for the proper functioning of the immune system, and appears to be a key nutrient in counteracting the development of virulence and inhibiting HIV progression to AIDS. It may reduce the risk of miscarriage. Selenium is required for sperm motility and is lost in semen.
Findings have been equivocal in linking selenium to cardiovascular disease risk although other conditions involving oxidative stress and inflammation have shown benefits of a higher selenium status.
Berzelius, a Swedish chemistry professor, discovered selenium in 1817. In 1957, Schwartz and Foltz established selenium as an essential trace element in nutrition for the prevention of disease.
The amount of selenium in the soil where food is grown, will strongly influence the levels of selenium in the foods we eat. It is well recognized that farm soil in the U.S. is very low in selenium, resulting in widespread selenium deficient food products.
Plants absorb selenium from the soil and convert it into organic forms that are easily assimilated. L-(+)- selenomethionine is the predominant form of selenium in wheat and cereals. L-(+)- selenomethionine is absorbed from the gastrointestinal tract.
Normal blood concentration level of selenium is 0.22mcg/100ml. Atomic # 34 Symbol - Se Atomic Weight - 78.96 Density - 4.79 g/cm3
High levels of vitamin C intererfers with Selenium Absorption
Deficiency Signs or Symptoms:
Indications of a Selenium deficiency include; age spots, liver spots and other liver problems, ALS (Lou Gehrig's Disease), Alzheimers Disease, cataracts, cancer risks, cystic fibrosis, retarded growth, "heart attack" (cardiomyopathy), impaired immunity, Keshan Disease (myocardial fibrosis), muscular dystrophy, pancreatic atrophy, fibrosis, liver cirrhosis, sterility in males, heart disease, dandruff, loose skin, premature aging, linked to adverse mood states, fatigue cancer (due to free radical damage), Atherosclerosis (due to free radical damage). Deficiencies in selenium have been linked to cancer and heart disease, exhaustion, cholesterol level problems, infections, pancreatic problems, stability and growth impairment, as well as, confusion, depression, fatigue and anxiety in the adult population.
Symptoms of toxicity include severe irritations of respiratory system, metallic taste in mouth, formication of nose, signs of rhinitis, lung edema and brancho-pneumonia. The garlic odor of breath and sweat is due to dimethyl-selenide
Possible interference with sulfur metabolism, impaired embryonic development, abnormal bone and cartilage development, blindness, salivation, muscle paralysis, abdominal pain, respiratory failure, liver disease, cardiomyopathy.
