Low plasma/serum selenium concentrations are associated with increased risk of death from heart disease and increased risk of death from all causes. Professor Urban Alehagen and a team of researchers at Linköping University in Sweden have investigated the relationship between low selenium levels and the risk of heart disease.
Selenium supplements suggested for adults with very low Se levels
The Swedish study shows that adults with a serum selenium concentration below 57 micrograms per liter are at significantly higher risk of death from all causes (43% increased risk) and death from heart disease (56% increased risk) [Alehagen 2016].
57 micrograms of selenium per liter of serum. Wow! That’s low.
These significant associations remained solid even after the researchers had adjusted for the effects of possibly modifying factors:
