Selenium (Se) is a trace element that is naturally present in many foods, is added to others, and is available as a dietary supplement. Selenium, which is nutritionally essential for humans, is a constituent of more than two-dozen selenoproteins that play critical roles in reproduction, thyroid-hormone metabolism, deoxyribonucleic acid (DNA) synthesis, and protection from oxidative damage and infection.
