Sheril Marek, M.S.Selenium is a trace element that is nutritionally essential for humans. Essential nutrients are required for normal body functioning that cannot be synthesized by the body. This shows the importance of consuming adequate selenium in one’s diet and supplements for enhanced exercise performance and decreased health risks. Selenium is a component of many selenoproteins that play a critical role in reproduction, thyroid hormone metabolism, DNA synthesis, and protection from o...

Majid Koozehchian, M.S. In our bodies, oxygen constantly produces toxic substances called reactive oxygen species (ROS), also known as oxidants. Antioxidants, biomolecules that combat oxidant damage, are produced by the body and can also be taken in supplement form. Disruption of normal cellular function by ROS is termed oxidative stress, and can be considered an imbalance between ROS production and the body’s production of antioxidants, weighted on the oxidant side (Fig.1). Low level...
