Selenium protects cells from oxidative stress.
Selenium has a vital role in boosting antioxidant activity in the body and providing protection against free radical damage.
Selenium is a constituent of more than twenty selenoproteins that play critical roles in reproduction, thyroid hormone metabolism, DNA synthesis and protection from infection. It also contributes to the maintenance of healthy skin, hair and nails.
Selenium functions as a component of glutathione, which accounts for its antioxidant function and its important contribution to the prevention of ageing and disease. Selenium and vitamin E work together synergistically in that they carry out antioxidant and immunostimulatory functions better together than individually. They both protect cell membranes and intracellular structural membranes from lipid oxidation. Solidification of tissue membranes occurs through the oxidation of fatty acids; selenium prevents or slows the biochemical ageing process of tissue degeneration and hardening - that is, loss of youthful elasticity. This protective function is enhanced by vitamin E.
The antioxidant function of selenium seems to decrease vascular clogging of inflamed artery linings by soothing irritation and binding free radicals; thus, selenium may play a role in reducing or preventing atherosclerosis at its initial biochemical level.
Selenium also helps stimulate antibody formation in response to vaccines. This immunostimulatory effect is also enhanced by vitamin E; research has shown that the presence of these two nutrients can increase antibody formation 20-30 fold.
Selenium protects from the toxic effects of heavy metals and other dangerous substances. People with adequate selenium intake have fewer adverse effects from cigarette smoking, alcohol, oxidised fats, and mercury and cadmium toxicity.
Through its glutathione-boosting properties, selenium aids red blood cell metabolism and has been shown to prevent chromosome damage in tissue cultures.
Selenium plays a role in protein synthesis, growth, development and fertility, especially male fertility. It has been shown to improve sperm production and motility.
Selenium absorption is thought to decrease with ageing and so higher quantities may be required as we grow older in order to reap all the protective, anti-ageing benefits of this mineral.Buy Lumity
