What is Selenium?

Essential Trace Element

szelén

Perhaps no other mineral can match selenium’s versatility and wide array of health benefits. Selenium is crucial for antioxidant defenses, boosts the immune system, and helps prevent cancer in several distinct ways.

What is the Physiological Role of Selenium?

Antioxidant, cancer prevention, synthesis of thyroid hormones

As selenocysteine, the 21st aminoacid, selenium is a component of selenoproteins, some of which have important functional and enzymic activities:

  • contributes to the proper functioning of the immune system, 
  • prevented the onset and development of several types of cancer in clinical studies
  • takes part in the synthesis of thyroid hormones
  • prevented the onset and deveopment of acrdiovascular diseases in clinical trials
  • contribute to the normal eyesight 1-3
Health Benefits of Selenium

Sources of Selenium

Soil in Europe Has a Low Selenium Content

With the exception of Brazil nuts and kidney, there are few good food sources of selenium in most European countries. Many people rarely eat foods that are good sources of selenium. Crab, liver, other shellfish, and fish are moderately good sources, although studies show marked differences in the ability of selenium from fish to increase selenium status.Meat, poultry, and fish make the biggest contribution to the consumption of selenium. Most European soils have a low content of selenium. Despite that, bread and cereals make a substantial contribution to selenium intake.

Why Is Selenium Substitution Important?

Selenium Depleted Soil, Uncertain Selenium Intake, Higher Risks of Diseases

Selenium is a trace element found to a varying extent in soil. It enters the human diet through plants such as whole grains and through the meat of animals grazing on vegetation containing selenium.

Low selenium status has been associated with increased risk of mortality, poor immune function, and cognitive decline. Higher selenium status or selenium supplementation has antiviral eff ects, is essential for successful male and female reproduction, and reduces the risk of autoimmune thyroid disease. Clinical studies have generally shown benefits of higher selenium status on the risk of prostate, lung, colorectal, and bladder cancers. People living in areas with low selenium content of the soil have the multiple risk of cancer disease, infection, and inflammation compared to individuals living in regions with high content of selenium. 4

What Type of Selenium Supplement to Choose?

100% organically bound selenium

kutatás

Selenium dietary supplements exist in the form of selenium salts (inorganic), or organically bound selenium (high selenium yeast or vagy selenomethionine). Selenium in foods is almost always in organic form . Selenium yeast contains more more selenium compounds than selenomethionine – this is one of the explanaitions of the huge diffferences in the outcomes between the two major cancer prevention studies conducted with selenium yeast (NPC 5) and selenomethionine (SELECT 6) .

In clinical studies, only SelenoExcell ® high selenium yeast reduced the incidence of several types of cancer – it was particularly effective in prostate and colorectal cancer. 7
