Selenium

Uses of Selenium

Supports immune function, thyroid health, and antioxidant protection. It also helps reduce oxidative stress, promotes heart health, and plays a role in cognitive function.

How Selenium Works

Acts as a powerful antioxidant by supporting the activity of glutathione peroxidase, an enzyme that protects cells from damage caused by free radicals. It also plays a crucial role in thyroid hormone metabolism and enhances the body's immune response.

Side Effects of Selenium

May cause nausea, hair loss, brittle nails, and in severe cases, selenium toxicity (selenosis), which includes symptoms like garlic breath odor, fatigue, and nervous system issues.

Information About Selenium

As an essential cofactor for selenoproteins including glutathione peroxidase and thioredoxin reductase, selenium is critical for thyroid hormone metabolism and antioxidant protection — supplementation above 400mcg daily risks selenosis characterised by hair loss, nail brittleness, and neurological symptoms.
