Selenium is one of those micro-nutrients which although required by the body in only tiny quantities are nevertheless vitally important for the health and well-being of the human organism.There’s now compelling evidence of selenium’s significance as an anti-oxidant, in fighting cancer and heart disease, and as a stimulant for the immune system.Selenium’s importance as an anti-oxidant lies principally in its necessity for the production of the key anti-oxidant enzyme, glutathione, which forms one of the body’s first lines of defence against dangerous superoxide free radicals. The body particularly needs the fat-soluble glutathione to work with vitamin E to soak up and neutralise any free radicals attacking the delicate yet vital fatty structures of cells such as the membranes.In this way selenium and vitamin E appear to work so closely together that a deficiency in one may be compensated for by the other, and selenium is also crucial as part of the enzyme thioredoxin reductase which is important in maintaining the anti-oxidant properties of vitamin C. Moreover, vitamin E cannot itself do its work in the absence of an adequate supply of active vitamin C; and vitamin C cannot remain active without the presence of glutathione.Selenium therefore forms […]
