What to watch with Selen and Langlebigkeit?

The provided context does not contain specific information on selenium and longevity. Generally, selenium is an essential trace element that acts as a cofactor for antioxidant selenoproteins (e.g., glutathione peroxidases). Some observational studies suggest a link between adequate selenium status and reduced risk of age-related diseases, but evidence for a direct extension of human lifespan is weak. Excess selenium can be toxic (selenosis). Without specific test results or risk factors (e.g., low-selenium soil), supplementation is not broadly recommended. Consumer DNA tests have limited predictive value for selenium needs. For longevity, focus on established factors like diet, exercise, and stress management.
