2. Possible Health Benefits
Among its many benefits, selenium has powerful antioxidant properties, which can help to prevent against cell damage that might otherwise cause cancer. These antioxidant properties may also help to reduce the risk of cognitive decline as a person ages.
Some studies have found that selenium is also helpful for: maintaining thyroid function, particularly in women; preventing HIV from progressing to AIDS; reducing the risk of miscarriage; and easing the symptoms of asthma. It’s important to note, however, that most of the research around selenium is still quite new, and none of its possible benefits have yet proven conclusive.
