Selenium is a trace element important for the proper functioning of many processes in the human body. It is a powerful antioxidant that contributes to the proper functioning of the immune system and the thyroid gland. Although selenium itself is a strong antioxidant, it enhances the action of other antioxidants in the body and proves particularly beneficial in cases of diabetes, eczema, asthma, cellular anomalies, and osteoarthritis.

Pregnant women with low selenium levels in their blood may have a higher chance of developing preeclampsia, a serious pregnancy complication. Research shows that taking up to 200 mcg of selenium daily may help with autoimmune thyroiditis and enhance the well-being and quality of life for individuals with this condition.

Selenium is also used as a supplement to support heart and blood vessel health, when used alongside cholesterol-lowering medications to reduce side effects. Taking selenium doses of 200 mcg daily may be beneficial for individuals with bone and joint disorders.
