Source: Cochrane
Area: Evidence > Complementary Medicine
Background
Selenium is a key component of a number of selenoproteins which protect against oxidative stress and have the potential to prevent chronic diseases including cardiovascular disease (CVD). However, observational studies have shown inconsistent associations between selenium intake and CVD risk; in addition, there is concern around a possible increased risk of type 2 diabetes with high selenium exposure.
Objectives
To determine the effectiveness of selenium only supplementation for the primary prevention of CVD and exam...

Selenium For Heart Disease Prevention In Well-Nourished Adults Not Supported By Current Evidence
A systematic review published in The Cochrane Library finds that in well-nourished adults current evidence does not support selenium for preventing heart disease. The review suggests that taking selenium supplements does not reduce a person's risk of developing heart disease, although most evidence is currently limited to healthy American adults. Diet is a key factor influencing heart disease risk. Selenium is one dietary element that could potentially play a role in preventing heart disease by protecting against oxidative stress and inflammation... (Source: Health News from Medical News Today)

Study finds no heart benefits from selenium
NEW YORK (Reuters Health) - Taking extra selenium supplements offers no protection against heart disease - at least among people who already get enough of the mineral in their diets, according to a new analysis of past research. In the review of 12 studies that included close to 20,000 people, there was no difference in the number of strokes and heart attacks, heart disease-related deaths or deaths from any cause among participants randomly assigned to take selenium or nothing.

Antioxidants Role in Chronic Disease Prevention Still Uncertain - Huge Doses Considered Risky
Insufficient evidence exists to support claims that taking megadoses of dietary antioxidants, such as selenium and vitamins C and E, or carotenoids, including beta-carotene, can prevent chronic diseases, says the latest report on Dietary Reference Intakes (DRIs) from the Institute of Medicine of the National Academies.
