How are Selen and Allergie related?

The relationship between selenium and allergies is not clearly established in the scientific literature. Selenium is an essential trace element that, as part of selenoproteins (e.g., glutathione peroxidases), plays a key role in antioxidant defense and immune regulation. Some observational studies suggest that low selenium status may be associated with a higher risk of allergic conditions such as asthma or atopic dermatitis. However, other studies found no significant link or even inverse associations. The evidence is therefore mixed. Genetic variants in selenoprotein genes (e.g., GPX1 rs1050450) can influence individual selenium requirements, but there are no specific guidelines for selenium supplementation to prevent allergies. A balanced diet with selenium-rich foods (e.g., Brazil nuts, fish, eggs) is generally advisable, but excessive intake should be avoided. MyBody-X tests can provide clues about selenium status or genetic predispositions, but they do not replace medical evaluation for existing allergies.
