Selenium is a trace mineral that is essential to good health but required only in small amounts. It is incorporated into proteins to make selenoproteins which are important antioxidant enzymes. Selenoproteins also help regulate thyroid function and play a role in the immune system.
In 2001 S. K. S. Sarada et al studied the antioxidant effect of selenium (Se) in reducing the hypoxia-induced oxidative stress. Results showed that selenium may help in reducing the lipid peroxidation during hypoxia, thus being a useful supplement to take at altitude.
