Selenium

Selenium is a vital mineral antioxidant that works together with Vitamin E. It is found in all the tissues of the body, but is most concentrated in the major organs.

Because of the severe mineral depletion of our soils, it is becoming more difficult to obtain adequate amounts of selenium and other minerals and nutrients from food. Because of this issue and because selenium is such a vital mineral nutrient involved in a large number of bodily processes, it sometimes is a good idea to consider a selenium supplement.

Make sure that your multivitamin has an adequate amount of selenium, vitamin E and other antioxidant nutrients.

The RDA (recommended dietary allowance) for most adults is 55 mcg per day, although an adult intake of 100-200 mcg of selenium per day is recommended by many doctors.

Research has found those given 200 mcg of yeast-based selenium per day for 4.5 years had a 50% drop in the cancer death rate. Studies have also shown that individuals suffering from heart disease respond well to selenium supplementation.
