Best Fit Profiles
- low-selenium dietary patterns and targeted repletion plans
Antioxidant enzyme and thyroid support
Selenium
Selenium clearly helps when intake is low; outside deficiency, benefits are smaller and most consistent in selected thyroid-autoimmunity profiles.
Evidence Level B
Evidence and Risk Labels
Evidence A/B/C reflects research maturity, and risk levels reflect monitoring needs. These labels support comparison, not diagnosis or treatment decisions.

- Effect Size
- High in deficiency correction; modest biomarker improvement in selected thyroid contexts
- Safety
- Moderate Risk
Narrow therapeutic window; chronic excess can cause adverse effects.
