Selenium levels and cholesterol

Studies have shown antioxidant properties of Selenium. More focus is being placed on the association between Selenium exposure and risk of metabolic disease, including cholesterol levels (1) . This study looked at toenail Selenium levels and dyslipidemia or lipid levels and to examine the effect of dietary supplement use. This was done in Korean adults. The results showed that there was no association between toenail Selenium levels and dyslipidemia or individual lipid profiles. The association was modified with dietary supplement use. In those using supplements, higher toenail Selenium was associated with a higher prevalence of lipid dysregulation, whereas non-users had a lower prevalence. The authors conclude that supplementation risks should be evaluated.
