Reduces Risk of Mental Diseases

Multiple studies have shown that Alzheimer’s patients tend to have low levels of selenium in their blood. Because of selenium’s positive effect on oxidative stress in the body, studies have also shown that the risk of developing diseases such as Parkinson’s and Multiple Sclerosis may be reduced with a diet rich in selenium.

Improves Heart Health

Selenium improves anti-inflammatory systems in the body, specifically preventing platelets in the body from clumping. Selenium also prevents the oxidation of lipids in the body, contributing to a decrease in risk for various heart diseases.
