Selenium Supplementation May Improve Total Cholesterol and Triglyceride Levels


Selenium is an essential mineral, meaning it must be obtained through diet or supplements. Previous studies have found that it helps support the immune system and cognitive function. Now a new study suggests that supplementation with selenium may help improve total cholesterol and triglyceride levels.





For their study, the researchers analyzed the results of 19 clinical trials that looked at the effects of selenium supplementation on blood levels of HDL cholesterol, LDL cholesterol, total cholesterol and triglycerides. The trials included a total of 3,881 participants.





The researchers found that selenium supplementation of 200??g/day significantly decreased serum levels of total cholesterol and triglycerides. These results were also found when baseline serum levels of total cholesterol were >200??g/dl. No significant results were seen for HDL or LDL cholesterol levels.





The study was conducted by researchers from Lorestan University of Medical Sciences, Iran. It was published online ahead of print on July 4, 2019 in the journal Obesity Medicine.
