Is Selen useful for Wechseljahre?

Selenium is an essential trace element important for thyroid hormone metabolism and antioxidant defense. During menopause, declining estrogen levels may increase oxidative stress and affect thyroid function. Some observational studies suggest that adequate selenium status is associated with fewer hot flashes and better bone health. However, the evidence is limited: no large randomized controlled trials have proven that selenium supplementation alleviates menopausal symptoms. Moreover, excess selenium is toxic (selenosis). Therefore, supplementation is only advisable if a deficiency is confirmed by blood testing (e.g., serum selenium). The recommended dietary allowance for women is 55 µg/day. A balanced diet including Brazil nuts, fish, and eggs usually meets requirements. Without deficiency, additional intake may cause more harm than benefit. In summary, selenium is not a magic bullet for menopause; maintaining adequate status is prudent, but supplementation should be guided by medical advice and lab results.
