Observational studies show an association between low vitamin D and increased allergy risk (e.g., asthma, atopic dermatitis). However, randomized controlled trials yield inconsistent results: supplementation does not reliably reduce allergy incidence and may cause harm at high doses (hypercalcemia, kidney stones). The 25-OH test measures vitamin D status, not allergy predisposition. Correcting a deficiency is sensible, but there is no proven 'anti-allergy dose'. Genetics, microbiome, and environmental factors are more influential. Bottom line: Vitamin D is an important immune modulator, but not a magic bullet for allergies.
