Myths vs facts: Selen and Abnehmen

Selenium is an essential trace element that supports thyroid function and antioxidant defense via selenoproteins. Some myths claim that selenium directly boosts fat burning or promotes weight loss. The scientific evidence for this is weak. Observational studies show an association between low selenium status and obesity, but this is likely due to poor diet quality rather than a causal effect. Intervention trials with selenium supplementation have not demonstrated significant weight loss. Moreover, high selenium intake can be toxic (selenosis), causing hair loss, nail brittleness, and nausea. The recommended dietary allowance is about 55–70 µg per day for adults; supplementation beyond food is rarely needed in well-nourished individuals. For weight loss, the focus should remain on energy balance, physical activity, and overall diet quality, not on single micronutrients. In summary: selenium is vital for health but not a weight-loss miracle. Myths often stem from exaggerated marketing claims.
