Selenium is an essential element in human nutrition. As an antioxidant, it is one of the substances that defend the body against the harmful effects of 'free radicals', the cell-damaging molecules formed when polyunsaturated fat oxidises. We should obtain enough Selenium from the food that we eat, but Britain's soil is now considered 'selenium poor' due to intensive farming. We have combined Selenium with Vitamins A, C and E to help maintain a healthy immune system, to help maintain healthy hair, skin, nails, teeth and gums, and to encourage normal growth.
