Sodium selenite, a form of selenium, is a trace mineral and works alongside vitamin E. It plays a key role in our health and can be found in plant foods, meat, seafood and of course, as a supplement. Our bodies only need a small percentage of selenium, however, it’s important that we do consume it as it helps activate antioxidant enzymes, maintain the function of many tissues in our bodies and prevent oxidative damage in the body.
Selenium is also an essential mineral and trace element. It works to recycle and re-use disease fighting antioxidant enzymes such as glutathione, which balances the damage caused from free radicals. It’s also necessary for maintaining healthy thyroid function.
When it comes to cancer, Selenium has backed up studies to show that selenium can indeed help protect us against two very common cancers, prostate and colorectal cancer. Low levels of selenium can lead to a two to threefold increase risk of cancer – particularly bladder, oesophagus, stomach, liver and lung cancer. However, thyroid cancer comes with a scary 8-fold increase risk when low levels of selenium are present in the body.
