All you need to know about Selenium
What are the benefits of selenium?
Selenium is good for treating conditions that are related to an underactive thyroid. Those that take up to 200mg of selenium every day are more likely to produce fewer antibodies that are linked to underactive thyroid. Selenium is also known to be a good mood-booster, and can also benefit those who suffer from conditions linked to weak bones and joint inflammation. Selenium can be used to treat high blood pressure and pregnancy complications such as pre-eclampsia. Pregnant women who take selenium have a reduced chance of developing pre-eclampsia.
What are the side effects of selenium?
Always consult your GP before taking selenium, to check that you are taking the right dose for your needs. It is advised that no more than 400mg of selenium is taken by mouth per day. Taking a dose higher than this can cause selenium toxicity, which can cause muscle pain and tenderness, circulatory problems, irritability, nausea and vomiting, hair loss, a metallic taste in the mouth and a lack of energy.
Can selenium help protect against heart disease?
It has been suggested in research that low levels of selenium contribute to a risk of heart disease. Taking selenium generally reduces inflammation in the body, and also reduces levels of the marker C-reactive protein (CRP), that can contribute to heart disease. The anti-inflammatory qualities of selenium help to prevent a build-up of plague in the arteries, thereby reducing your risk of heart disease and other problems like stroke and heart attacks.
Which foods are high in selenium?
There are many healthy foods that are high in selenium, including tuna, halibut, sardines, chicken, shiitake mushrooms, eggs, oysters, Brazil nuts and sunflower seeds.
