Natural Remedies for Immunity

Selenium

Selenium is a trace mineral that our bodies use to produce glutathione peroxidase, an enzyme that serves as a natural antioxidant. Glutathione peroxidase works with vitamin E to protect cell membranes from damage caused by free radicals. Selenium rank with vitamins C and A as a powerful promoter of immunity. (1)

The importance of selenium in thwarting viral infections is illustrated by the fact that a number of deadly viruses (such as HIV, Ebola, etc.) have emerged from regions in Africa such as Zaire, which appear to be selenium deficient. 

Selenium is essential for healthy immune functioning. Selenium supplementation reduces the incidence of hepatitis in deficient populations.(2) In a population of elderly people that was not deficient in selenium, selenium supplementation has been found to stimulate the activity of white blood cells-primary components of the immune system.(3) Selenium is also needed to activate thyroid hormones. Selenium provides protection against a large number of cancers and, against a broad spectrum of diseases.

Selenium is an essential component of a powerful antioxidant manufactured by the body. This antioxidant, called glutathione peroxidase, defends specifically against peroxides, a type of free radical that attacks fats. Like other antioxidants, glutathione peroxidase also reduces the risk of developing cancer and heart diseases and stimulates the immune system's response to infections.
