    In people with hardened arteries, sodium selenite lowered some inflammation markers and raised antioxidant levels, but scientists say more research is needed.

How it’s made and used

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least two findings in people. Findings whose study type is not stated are shown but not counted. This page is a reference, not medical advice. It describes what regulators and published research say. Talk to a doctor or dietitian about your own diet.
