- Immune System Enhancement: Adequate selenium levels help boost immune response, reducing the risk of infections.
- Thyroid Function Regulation: Selenium is essential for the synthesis of thyroid hormones, which regulate metabolism.
- Cancer Prevention Potential: Some studies suggest selenium may reduce the risk of certain cancers by protecting DNA from damage.
