Myths vs facts: Zink and Allergie

Zinc is an essential trace mineral important for immune function. Some studies suggest a link between zinc deficiency and increased allergy risk, as zinc modulates inflammatory responses and immune cell activity. However, the evidence is mixed: observational studies sometimes show lower zinc levels in allergy sufferers, but robust RCTs proving causality or therapeutic benefit of zinc supplementation for allergies are lacking. Moreover, consumer zinc blood tests can be unreliable due to diurnal variation and inflammation. High-dose zinc (>40 mg/day) can cause copper deficiency and other side effects. Bottom line: Zinc is relevant for immune health, but its role in allergies is not strongly established. A balanced diet or targeted supplementation under medical guidance is advisable, not self-diagnosis.
