Healing Power of Selenium

Selenium is key component of the enzyme glutathione which is one of the body’s most powerful antioxidant. Glutathione will break down toxins and bind to heavy metals thereby protecting cells from free radical damage.
Selenium protects against damage that leads to heart disease and stroke. It also strengthens immunity and may enhance longevity.
A study showed when used in synergy with Vitamin E, selenium helped elderly subjects improve mental alertness, emotional wellbeing, poor appetite and fatigue.

Selenium deficiency is becoming more prevalent. This could be due to agricultural methods leaching the soil or sulphur from acid rain competing with selenium for uptake in plants.
There was an interesting finding where a form of heart disease called Keshan disease was eradicated in an area of China after finding that the soil was deficient in selenium.
After supplementing the local population with selenium, Keshan disease virtually disappeared. Selenium deficiency can also cause infertility, SAD syndrome, CFS, muscular dystrophy, liver cirrhosis and cystic fibrosis.
