Selenium's Selenium 100μg nutritional supplement contains selenium, an essential trace element that works in synergy with vitamin E. As a component of the antioxidant enzyme glutathione peridoxase, selenium neutralizes free radicals before they break down the body's tissues. Selenium is essential for smooth development and can positively protect against the development of cardiac and other degenerative diseases. At the same time, it is very useful for detoxification from toxic metals, such as mercury and cadmium. Solgar's Selenium Nutrition Supplement provides a non-yeast organic form of selenium. Packaging: glass vial with 100 tablets of 100μgr.
