Selenium is an essential trace mineral that works with Vitamin E in metabolic functions. It promotes normal body growth, enhances fertility, encourages tissue elasticity and is a potent antioxidant that naturally reduces the retention of toxic metals in the body. Selenium is crucial for the proper functioning of the heart muscle and there is evidence that it can help the body fight cancer. The people of Norfolk England are said to be among some of the longest-lived. Scientists believe it is due to high concentrations of selenium in the soil. A low level of selenium in soil has long been associated with higher cancer rates. Selenium is stored in muscle and other tissues, as well as in the liver and kidneys.
