Myths vs facts: Selen and menopause

The question about myths vs facts regarding selenium and menopause is not directly addressed in the provided context. Generally, selenium is an essential trace element that acts as a cofactor for antioxidant selenoproteins (e.g., glutathione peroxidases) and supports thyroid function. During menopause, declining estrogen levels increase oxidative stress, so adequate selenium might theoretically be protective. However, human evidence is mixed: some observational studies link low selenium status to hot flashes or mood changes, but robust randomized controlled trials are lacking. Dietary supplements are often marketed with exaggerated claims (e.g., 'anti-aging'). Overdosing (>300 µg/day) can cause selenosis (toxic effects). Consumer DNA or biomarker tests measuring selenium provide only a single snapshot and do not replace clinical assessment. Conclusion: evidence is weak to moderate; a balanced diet (e.g., Brazil nuts, fish, eggs) usually meets requirements. Supplement only after medical consultation.
