NOW Foods Selenium 100 mcg

Selenium is a trace mineral essential to the production of the premier antioxidant glutathione peroxidase. It bonds with methionine, a naturally occurring amino acid in the diet. The best food sources of selenium include Brazil nuts, seafood, organ meats, and wheat germ. Selenium’s antioxidant mechanisms can support the body’s proper enzymatic activities that may help protect against some forms of cancer.

  • Selenium supports glutathione peroxidase synthesis. Glutathione is the most powerful antioxidant in the human body that helps protect cells against destructive free radicals. Stress, pollution, drugs, infection, radiation, and normal ageing cause accumulation of these unstable oxygen species that can lead to the onset of premature ageing and age-related diseases.
  • Selenium can also promote healthy heart functions. Deficiency of this trace mineral is associated with cardiomyopathy, a heart condition characterised by the weakening of the heart muscles. The most common theory on the cause of cardiomyopathy is the lack of energy in the cells of the cardiac muscles. Antioxidants can provide an additional supply of energy to the heart muscles so it can pump more blood to transport to other organs and tissues.
  • Although not conclusive, research suggests that selenium may help reduce the risks from certain forms of cancer. Some experts claim that prostate cancer is associated with low selenium levels, making the prostate gland at risk to cell damage from free radicals. This trace mineral can provide increased antioxidant protection for optimum prostate health.
  • Selenium can help control asthma attacks. People with asthma often don’t have enough selenium in their blood, which increases the risk for the occurrence of its symptoms. Other antioxidants that may help asthma include Vitamins C and E.
  • This trace mineral can be beneficial to the skin, nails, and scalp. It can often be used as an active ingredient for anti-dandruff shampoos. For skin care, it helps regenerate the vitamin antioxidants C and E to help prevent the appearance of the visible signs of ageing like wrinkles and fine lines. Selenium can also promote normal healing from wounds, burns, and other injuries.

Selenium is one of the essential trace minerals. It is found in the soil and in a variety of food sources like brazil nuts, brown rice, organ meats, seafood, and poultry. Although the body needs it in trace or very little amounts, there are still a lot of people are not getting enough selenium in their bodies.
The body uses it to produce glutathione peroxidase, a very powerful antioxidant. People who are low in selenium consequently can be low in glutathione, increasing their risk for free radical damage. Low levels of this mineral can commonly be seen in people with prostate cancer, asthma, cardiomyopathy, and mal-absorption. On the other hand, consumption of selenium-rich foods can promote immune health, healthy energy levels, youthful vitality, healthy skin, and optimum thyroid functions.
