Selenium (selenomethionine)

Selenium is a natural antioxidant that delays the oxidation of polyunsaturated fatty acids and preserves the elasticity of tissue. Selenium is required for the production of certain prostaglandins, which promote healthy blood flow. Selenium may also help support healthy growth and fertility, as indicated in a research study using a combination of selenomethionine and vitamin E. Selenium also provides support for the immune system. Selenomethionine serves as a storage form of selenium. It is incorporated into proteins and released as the proteins are catabolized.^‡
