Selenious acid is the acid form of sodium selenite, a form of selenium 8.
Selenium is an essential trace element and antioxidant. It is a cofactor metabolic enzyme regulation. It also plays an important role in maintaining the general health of tissue and muscle and has antioxidant properties. Selenium is a component of glutathione peroxidase enzyme, which protects cell components from oxidative damage due to peroxides produced during cellular metabolism 13.
Selenium (Se) has been demonstrated to prevent cancer in numerous animal models when administered selenium at levels exceeding the nutritional requirements. One study showed efficacy in the prevention of malignancy while utilizing a selenium supplement in humans. The reports from such studies have heightened the interest in additional human selenium supplementation studies to validate the results in larger populations 15.
Interestingly, selenium is being studied as a potential therapy in the prevention or management of atherosclerosis 18.
