Selenium is an essential trace mineral that supports antioxidant defense through selenoproteins such as glutathione peroxidase. The brain is vulnerable to oxidative damage, and adequate selenium status has been associated with better cognitive outcomes in observational studies, particularly in populations with low baseline selenium.

What dosage of Selenium has been used in cognitive studies?

The recommended dietary allowance for selenium is 55 mcg per day for adults. Cognitive studies have used 100 mcg to 200 mcg daily. Selenomethionine and selenium yeast are common supplemental forms. The tolerable upper intake is 400 mcg per day. Consult your healthcare provider.

What are the potential side effects of Selenium?

Chronic intake above 400 mcg per day may cause selenosis, characterized by garlic breath, hair loss, brittle nails, and neurological symptoms. Selenium has a narrow therapeutic window. Consult your healthcare provider and consider testing your selenium status before supplementing.
