Selenium is an essential micronutrient for human health. In the body, it is incorporated into enzymes and other proteins to make vital compounds known as selenoproteins.1 Perhaps the best-known selenoprotein is the antioxidant enzyme glutathione peroxidase. Each molecule of glutathione peroxidase requires four selenocysteine units and catalyzes a reaction in which a free radical is scavenged by glutathione.2
